Officieel: BMW X6 en 7-Reeks ActiveHybrid

bmw_x6_activehybrid
BMW heeft hybride varianten van de BMW X6 en de BMW 7-Reeks uitgebracht, dit onder de noemer ActiveHybrid.

Echt milieuvriendelijk zijn beide wagens natuurlijk niet te noemen, ze worden namelijk beiden aangedreven door een V8 benzinemotor, die in combinatie met twee elektromotoren voor de aandrijving zorgt. Hybride is de wagen dus zeker en vast, milieuvriendelijk is een andere zaak.

Efficiënter zijn de wagens er alleszins wel op geworden. De motor verbruikt 20% minder dan voorheen en stoot een gelijk percentage minder CO2 uit. Het is bijvoorbeeld perfect mogelijk 60 km/u te rijden, zonder ook maar een gram CO2 uit te stoten. Rijd je iets sneller, dan helpt de V8-motor je snelheid te maken.

De V8-motor, die met de BMW TwinPower Turbo, levert 407 pk en werkt samen met twee elektromotoren, die respectievelijk 91 en 86 pk leveren. De maximum output van het totale systeem komt neer op 485 pk, met een trekkracht van 780 Nm. Dat maakt van de BMW ActiveHybrid X6 de meest krachtige hybride ter wereld. Het gemiddelde verbruik komt neer op 9,9 liter per 100 km, wat al bij al goed meevalt voor een wagen die 485 pk levert. Echt milieuvriendelijk is dat natuurlijk niet, efficiënt is het zeker en vast. De schadelijke CO2-uitstoot wordt beperkt tot 231 gram per kilometer. De topsnelheid werd beperkt tot 236 km/u en de nul-naar-honderd-tijd komt neer op een verbazingwekkende 5,6 seconden.

Waarom twee elektromotoren, vraag je je ongetwijfeld af. Wel, één van die motoren dient om de wagen aan te drijven bij lage snelheden, de andere staat deze hybride bij wanneer je snel begint te rijden. Zo kan er bij elk gebruik van de wagen onder optimale omstandigheden gereden worden.

Ook de 7-Reeks maakt gebruik van een V8-benzinemotor, maar wordt aan een automatische versnellingsbak met 8 verzetten gekoppeld, in plaats van 7. De V8-motor die in de 7-Reeks schuilt werkt met slechts 1 elektromotor samen, die samen met de V8 voor een totale output van 465 pk zorgt en 700 Nm. Nul naar honderd doet deze 7-Reeks in amper 4,9 seconden en het verbruik bedraagt slechts 9,4 liter per 100 km. Per kilometer stoot de BMW ActiveHybrid 7-Reeks 219 gram CO2 uit.

BMW ActiveHybrid 7-Reeks:

BMW is proud to present the most supreme and luxurious rendition of
hybrid technology ever seen so far in the automobile: BMW ActiveHybrid 7.

Based on the BMW 7 Series, this unique car sets new standards for effi ciency
in the luxury class. BMW ActiveHybrid 7 is the fi rst car in the world to combine
a V8 gasoline engine, eight-speed automatic transmission and an electric motor
as a mild hybrid concept.

This symbiosis of an upgraded eight-cylinder with BMW TwinPower Turbo
Technology and High Precision Injection with a three-phase synchronous electric
motor gives BMW ActiveHybrid 7 overall system output of 342 kW/465 hp
and maximum torque of 700 Newton-metres/516 lb-ft. Power is transmitted
via an eight-speed automatic transmission, with the electric motor positioned
in compact confi guration between the combustion engine and the converter
on the automatic transmission receiving its supply of energy from a lithium-ion
battery developed especially for use in the automobile.

Precisely controlled interaction of both power sources serves to optimise not
only the effi ciency but also the dynamic performance and superior comfort of
BMW ActiveHybrid 7. The result is a truly thrilling driving experience and, at the
same time, a unique demonstration of hybrid technology with its outstanding
potential. BMW ActiveHybrid 7accelerates to 100 km/h in a mere 4.9 seconds,
while keeping average fuel consumption in the EU test cycle to 9.4 litres/
100 kilometres (equivalent to 29.1 mpg imp) and restricting CO2 emissions to
just 219 grams per kilometre.

Hybrid technology also provides new options for the particularly effi cient
use and enjoyment of additional comfort functions. As an example,
BMW ActiveHybrid 7 is the fi rst BMW with automatic transmission to feature
an Auto Start Stop function avoiding idle speed operation of the engine
when at a standstill or in traffi c jams. A further signifi cant advantage is that
the air conditioning and ventilation system remains fully operational also with
the engine switched off, power being supplied directly through the 120-volt
on-board network operating on the lithium-ion battery.

This unique concept of engine management for the first allows truly effective
climate control also at a standstill in a luxury performance car, cooling the interior
of BMW ActiveHybrid 7 to a signifi cantly lower temperature right from the start,
before the driver even fi res the engine.

Special displays in the instrument cluster and the Control Display inform the
occupants of the degree of effi ciency and the current operating status of the
hybrid components. Nineteen-inch light-alloy rims in aerodynamically optimised
ten-spoke turbine wheel design created exclusively for BMW ActiveHybrid 7 as
well as model designations on the luggage compartment lid, the C-pillars
behind the side windows and on the door cutouts clearly set aside the hybrid
models from their “regular” counterparts right from the start. And last but
certainly not least, BMW ActiveHybrid 7 is also available in Bluewater metallic
exterior paintwork exclusive to this very special model.

Like the existing models within the BMW 7 Series, BMW’s fi rst luxury saloon
with hybrid drive is entering the market in two body variants. The extended
version of BMW ActiveHybrid 7 comes with wheelbase increased by 14 centimetres
or 5.5″, benefi ting exclusively the rear-seat passengers. And to optimise
the driving experience and grand touring comfort for individual requirements,
both models are available with a wide range of options from the portfolio of
equipment and accessories offered on the BMW 7 Series.

BMW ActiveHybrid X6:

The BMW ActiveHybrid X6 is the world’s first Sports
Activity Coupé
with full hybrid drive offering a driving
experience quite unique both in
the segment of BMW X models and
in the hybrid segment as a whole. Through its combination of a V8
gasoline engine and electric drive,
the BMW ActiveHybrid X6
offers a significant increase in dynamic performance together with a
reduction of fuel consumption and emissions by approximately 20 per
cent. This joint enhancement of driving pleasure and efficiency
clearly proves that the BMW ActiveHybrid X6 is a typical BMW in
the hybrid segment.

BMW ActiveHybrid technology offers the driver three significant
options: to drive under electric power alone, to use the power of the
combustion engine, or to benefit form the combination of both drive
modes. Driving completely free of CO2 in the electric mode is possible
up to a speed of 60 km/h or 37 mph. The combustion engine then cuts in
as required
(as a function of load conditions) and is
automatically switched off when driving in overrun at a speed of less
than 65 km/h or 40 mph.

The drive system featured in the BMW ActiveHybrid X6 consists of
a 300 kW/407 hp V8 power unit with BMW TwinPower Turbo
Technology and two electric motors developing 67 kW/91 hp
and, respectively, 63 kW/86 hp. Maximum system output is
357 kW/485 hp, peak torque is 780 Newton-metres/575
lb-ft. This makes the BMW ActiveHybrid X6 the most powerful
hybrid vehicle in the world.

Through its unique balance of performance and fuel economy the

BMW ActiveHybrid X6 sets new standards both in the hybrid
vehicle segment and in the overall market of BMW X models.
Acceleration from
a standstill to 100 km/h comes in 5.6 seconds.
Average fuel consumption in the EU5 test cycle is 9.9 litres/100 km
(equivalent to 28.5 mpg imp),
the CO2 emission rating is 231 grams/kilometre.

Integration of the two electric motors in the two-mode active
transmission of the BMW ActiveHybrid X6 allows two self-sufficient
modes of operation. One mode is for setting off in particularly
dynamic style and for driving at low speeds, the second is for driving
at a higher speeds under optimum conditions. This ensures all the
benefits of BMW ActiveHybrid technology, with maximum efficiency under
all loads and at all speeds. At the same time the seven-speed
automatic transmission provided by the electric motors together with
three planetary gearsets and four multiple-plate clutches ensures all
the supreme driving behaviour, smoothness and performance so typical
of BMW.

When applying the brakes or taking back the gas pedal kinetic energy

is converted into electrical energy and stored in the
high-performance battery. To provide this benefit either one or both
electric motors act as
a generator, depending on driving
conditions. The recuperation efficiency and output achieved by the
system is 25 times greater than with Brake Energy Regeneration
featured so far in BMW’s production models.

Electrical energy is stored in an NiMH high-performance battery with

a capacity of 2.4 kWh. The temperature of the high-voltage
battery is controlled as required and with maximum efficiency by
liquid cooling interacting with the air conditioning and an external
heat exchanger.

The central electronic control unit ensures appropriate interaction

of the combustion engine and electric drive crucial to the
outstanding efficiency and unique qualities of the BMW
ActiveHybrid X6. It converts high-voltage direct current from the
high-performance battery into
three-phase alternating current
for the two electric motors in the hybrid transmission. It also
coordinates all functions of the hybrid system including the
distribution of torque and power between the combustion engine and the
electric motors as well as the selection of gears.

Over and above the electric motors, the high-performance battery

also supplies electrical energy to the power-consuming items
linked to
the 12-volt on-board network. The BMW
ActiveHybrid X6 is equipped with electromechanical power steering
and an electrical climate compressor both remaining fully functional
also when the combustion engine is switched off and enhancing the
overall efficiency of the vehicle to an even higher standard through
their on-demand consumption and uptake of energy.

While braking the generator builds up stopping forces in the electric
motors acting efficiently on all four wheels and precisely coordinated

with the hydraulic brake effect in accordance with the
driver’s stopping and deceleration requirements. This provides
not only optimum stopping power, but also the brake feeling so typical
of BMW under all driving conditions including the all-electric mode. A
further point is that like the BMW X6, the BMW ActiveHybrid X6
comes with Dynamic Stability
control incorporating an enhanced
range of functions such as Dry Braking and Fading Compensation as well
as an electromechanical and hydraulic parking brake complete with an
Auto-Hold function.

In its driving behaviour and motoring comfort, the BMW
ActiveHybrid X6 offers all the standards provided by BMW’s
latest X models, without
the slightest difference between the
electrical and the combustion drive mode. Intelligent xDrive
all-wheel-drive technology with permanent, variable power distribution
front-to-rear enhances the unique driving dynamics of the vehicle to
an even higher standard.

The current operating mode and function of the drive system is
clearly presented by appropriate displays in the instrument cluster
and in the Control Display itself. The charge level of the
high-performance battery
at the disposal of the driver and the
current operating mode are shown
by appropriate gauges beneath
the rev counter. Being informed of the power uptake when driving in
the electric mode, the driver may if he
wish maintain that mode
longer in the interest of extra efficiency. And if
he wishes the
driver may also call up information on the current flow of energy in
the Control Display.

The particularly prominent Powerdome on the engine lid gives the

BMW ActiveHybrid X6 a very distinctive look versus the
“regular”
BMW X6 as a significant visual highlight.
“ActiveHybrid” model designations on the tailgate trim bar
and on the front doors, the designation “BMW ActiveHybrid”
on the door entry covers on either
side, 19-inch light-alloy
wheels (or, as an option, 20-inch light-alloy
wheels in
aerodynamically optimised Streamline design), as well
as
exterior paintwork in exclusive Bluewater metallic for the first time

on a BMW X6 serve furthermore to highlight the particular
character
of this unique car.

The BMW ActiveHybrid X6 combines innovative drive technology
with
the unique concept of a Sports Activity Coupé. The
very progressive
and exclusive character of this outstanding
vehicle is further underlined
by a particularly wide range of
standard features as well as attractive options. The BMW
ActiveHybrid X6 comes as standard with features
such as
comfort seats, automatic air conditioning, cruise control, the

BMW Professional navigation system and Park Distance Control.

A further important feature is the electrical opening and
closing
function on the tailgate. Options include an extended
range of nappa leather upholstery in an exclusive Ivory White/Black
colour combination complete with double blue seams, a glass
sliding/vent roof, a trailer towbar, as well as the complete range of
BMW ConnectedDrive including innovative driver assistance systems.

The safety features offered by the BMW ActiveHybrid X6 include
frontal and side airbags, head airbags at the side, crash-activated
headrests
at the front, runflat tyres as well as a Tyre Defect
Indicator enabling the driver to monitor the pressure individually in
each tyre. BMW Adaptive Headlights complete with a Bending Light
function supplement the
bi-xenon headlights with their daytime
driving lights featured as standard.

Fascinating Efficiency:
The BMW ActiveHybrid X6.

BMW ActiveHybrid technology combines superior driving dynamics with
equally superior efficiency pointing far into the future, brining
together both
of these qualities to offer a truly unique driving experience.

The world’s first Sports Activity Coupé with full hybrid
drive therefore capitalises on the options offered by combining the
combustion engine
and the electric motor with a standard of
perfection never seen before.
BMW
ActiveHybrid technology offers a significant increase in driving
dynamics and at the same time reduces fuel consumption by
approximately 20 per cent versus a comparable vehicle powered by a
combustion engine alone. The result is even greater Sheer Driving
Pleasure combined with enhanced fuel economy and CO2 management
providing the kind of progress to make the BMW ActiveHybrid X6 a
typical BMW in the hybrid market.

The overall drive system featured in the BMW ActiveHybrid X6
consists of a 300 kW/407 hpV8 gasoline engine with BMW
TwinPower Turbo Technology and two electric synchronous motors
delivering 67 kW/91 hp and, respectively,
63 kW/86 hp. Maximum system output is
357 kW/485 hp, peak torque is 780 Newton-metres/575 lb-ft.

Precisely controlled interaction of the three power units optimises
the
overall efficiency of the BMW ActiveHybrid X6 at all
speeds, with
acceleration from a standstill to 100 km/h in 5.6
seconds. Top speed of
the BMW ActiveHybrid X6 is limited
electronically to 236 km/h or 146 mph (250 km/h or 155 mph with the
optional Sports Package, with average fuel consumption in the EU test
cycle of 9.9 litres/100 km (equal to 28.5 mpg imp) and a CO2 emission
rating of 231 grams per kilometre.

BMW’s first full hybrid model is able to run exclusively on
electric power
– and that is entirely free of CO2 –
up to a speed of 60 km/h or 37 mph, with
the combustion engine
being activated automatically whenever required.

Ideal variation of the two drive modes for enhanced efficiency and

dynamism is ensured by The two-mode active transmission provides
the
ideal combination of the two power modes for enhanced
efficiency and dynamic performance at all times. With the two electric
motors, three planetary gearsets and four multiple-plate clutches,
drive power is transmitted through a seven-gear automatic transmission
operated by the driver of the BMW ActiveHybrid X6 via an
electronic gear selector lever and, respectively, shift paddles on the
steering wheel.

BMW’s intelligent xDrive all-wheel-drive system spreads out
engine power variably between the front and rear wheels.

The electric motors receive their energy from an NiMH
high-performance battery positioned beneath the floor of the luggage
compartment and
feeding electric power also to the car’s
on-board network. Luggage compartment capacity is therefore the same
as on the “regular” BMW X6
with its combustion
engine. When applying the brakes or taking back the
gas pedal
kinetic energy is converted into electrical energy and is stored in
the high-performance battery. To provide this function either one or
both of the electric motors acts as a generator, feeding electric
power generated without the slightest increase in fuel consumption
directly into the high-voltage battery. Subsequent use of this energy
to provide extra drive power

significantly reduces the consumption of fuel.

BMW ActiveHybrid technology raises the development of drive
systems enhancing both efficiency and dynamism in one to a new,
unprecedented standard, clearly confirming BMW’s superior
competence in development
in this area. Now the introduction of
this innovative technology in such an exceptional vehicle concept adds
a particularly fascinating motoring experience through the efficiency
achieved in this way. Through its size, character and driving
dynamics, the world’s one and only Sports Activity Coupé
is particularly well-suited to combine the progressiveness and the
potential of BMW ActiveHybrid technology to a standard never seen before.

Unique efficiency ensured by two-mode active transmission.

BMW ActiveHybrid technology has been developed specifically for use
in a particularly dynamic vehicle in this segment and for a broad
range of practical use going far beyond city traffic as such. The big
advantage, therefore, is the overall optimisation of drivetrain
efficiency in all speed ranges and under all conditions.

The two-mode active transmission is based on an ECVT (electric
continuously variable transmission) operating in two separate modes.
One mode is for setting off with particular power and for driving at
low speeds, the second is for motoring at high speeds.

When setting off only one of the two electric motors is activated.
Then,
as soon as the driver requires more power, the second
electric motor automatically activates the combustion engine and
subsequently serves
as a generator providing a permanent supply
of electric power.

When driving steadily at a higher speed most of the power required is
delivered by the combustion engine in a largely mechanical process.
Here again, one of the two electric motors acts as a generator.

Together with the mechanical components, the electric motors form a
joint transmission unit providing the optimum transmission ratio at
all times as a function of driving conditions. The mechanical link
within the two-mode
active transmission is provided by three
planetary gearsets in a configuration dividing the drive power
generated by the combustion engine and the two electric motors into
two transmission modes and therefore ensuring a degree of variability
in combining the two power sources conventional hybrid drive would not
be able to provide.

The two operating modes of the electric motors are supplemented and
enhanced by fixed transmission ratios providing a total of seven gears
for full use of the highly efficient hybrid function throughout the
vehicle’s complete range of operation and at the same time
maintaining the driving performance so typical of BMW.

Conventional but unique all in one: V8 gasoline engine with BMW
TwinPower Turbo Technology and High Precision Injection.

The combustion engine is a technically unique eight-cylinder featured
for
the first time in the BMW X6 xDrive50i. The world’s
first V8 gasoline engine with two turbochargers in the V-section
between the two rows of cylinders excels in particular through its
smooth development of power setting in
from the start and
continuing in an ongoing surge throughout the entire speed range. The
exceptionally spontaneous and direct response of this V8 with BMW
TwinPower Turbo Technology results directly from the compact
configuration of the engine allowing short manifolds as well as large
cross-sections on the intake and exhaust side.

Displacing 4.4 litres, this outstanding eight-cylinder delivers
maximum output of 300 kW/407 hp consistently maintained
between 5,500 and 6,400 rpm. Superior torque of
600 Newton-metres/442 lb-ft is maintained all the way from 1,750
to 4 ,500 rpm, with High Precision Injection ensuring precise
supply of fuel at all times.

Piezo-injectors positioned in the middle between the valves ensure a

smooth, efficient and clean combustion process, the V8 naturally
fulfilling both the European EU5 standard as well as the ULEV II
limits in the USA.

Compared with the power unit featured in the BMW X6 xDrive50i, this

new engine has been modified in numerous respects to the
specific requirements of the BMW ActiveHybrid X6. The first point
is that there is
no starter, no alternator and belt drive for
the climate compressor and hydraulic pump on the power steering. The
main and low-temperature circuits in the cooling system have been
modified for all-electric operation,
the low-temperature circuit
already serving to cool the charge air in the combustion engine being
used additionally to cool the power electronics.

A specifically designed hybrid engine cover, finally, marks a clear
difference versus the power unit in the BMW X6 xDrive50i.

Electric motors for enhanced performance on no extra fuel.

When accelerating the eight-cylinder power unit of the
BMW
ActiveHybrid X6, joining forces with the electric motors, ensures
optimum efficiency and dynamic performance. As soon as the driver

requires more power the two electric motors fed by the
high-voltage energy battery supply additional torque for enhanced
performance. This boost
effect significantly increases the
overall output of the BMW ActiveHybrid X6, without any increase
in fuel consumption.

While the two electric motors have almost the same output, they have

been modified in their performance characteristics to meet
individual requirements. The power delivered is 67 kW/91 hp
and. respectively, 63 kW/86 hp, with peak torque of 260
Newton-metres/192 lb-ft and 280 Newton-metres/206 lb-ft.

The electric motors support the combustion engine effectively
throughout the entire speed range, the additional electrically
generated drive power serving to reduce the power output required on
the combustion engine when driving steadily at a higher speed. This
shift in load is perfectly controlled
at all times to give the
overall system enhanced efficiency and its maximum effect under
practical driving conditions.

The electronic control unit is also able to provide a consistent,
ongoing
surge of power, maximum power being generated when
shifting gears through the so-called response boost effect. When
kicking down the accelerator for maximum acceleration, the control
unit generates stationary boost right from the start in the initial
downshift phase, interaction of response boost and stationary boost
ensuring a very spontaneous and direct response to every movement of
the gas pedal.

Maximum system output is 357 kW/485 hp, with peak torque of
780 Newton-metres/575 lb-ft. This makes the BMW
ActiveHybrid X6 the most powerful hybrid vehicle in the world,
with acceleration from a standstill to 100 km/h in just 5.6 seconds
and top speed is limited electronically to 236 km/h or 146 mph (or,
respectively, 250 km/h or 155 mph with the optional Sports Package).

The unique positon of BMW ActiveHybrid X6 within the BMW X
segment
as a whole follows very clearly and convincingly from
the comparison of these performance figures, on the one hand, with the
vehicle’s fuel consumption
and emission ratings, on the
other. The BMW ActiveHybrid X6 combines its supreme dynamism with
equally fascinating efficiency, with fuel average fuel consumption in
the EU test cycle of just 9.9 ltr/100 km (equal to 28.5 mpg imp) and a
CO2 rating of 231 grams per kilometre.

All-electrical driving mode reducing emissions to zero.

With its combination of two-mode active transmission and
high-performance battery, the BMW ActiveHybrid X6 is able to run
on its electric motors alone. This makes it a zero emission vehicle
under such conditions, fulfilling even the strictest requirements
foreseen for the future and ensuring the highest conceivable level of mobility.

The BMW ActiveHybrid X6 may run on electric power alone
regardless of the ambient temperature, minimum operating temperatures
being required only for the engine coolant, transmission fluid and
high-voltage battery. A further requirement is that the
high-performance battery is adequately charged.

Top speed in the electric mode is 60 km/h or 37 mph, maximum
range is
2.5 kilometres (1.6 miles).

While driving electrically, the BMW ActiveHybrid X6 retains all
its safety
and comfort functions. The brakes remain fully
operative thanks to electronic vacuum supply, not requiring the
combustion engine to develop their full effect. The same applies to
the EPS Electronic Power Steering, with steering assistance being
generated as required and with maximum efficiency by
an electric motor.

Even the air conditioning remains fully available without any
restrictions, running efficiently on an electrical climate compressor.
And since the high-performance battery supplies electric power to the
complete 12-volt on-board network through a voltage converter
regardless of the driving mode, all other power-consuming items such
as the lights and the on-board entertainment system remain fully
functional at their usual, consistent level.

Recuperation: electric power generated without additional fuel consumption.

The BMW ActiveHybrid X6 features an enhanced version of Brake
Energy Regeneration already used in BMW’s current models running
on a combustion engine alone, generating the electric power saved in
the high-performance battery. In this case the electric motors act as
generators in overrun and when applying the brakes in order to feed
electric power into the high-voltage battery unit, again in the
interest of maximum efficiency.

This uses energy otherwise simply lost in conventional vehicles as
heat escaping through the brakes – and depending on road speed,
one or both
of the electric motors may perform this function.

The power delivered by the generator is approximately 50 kW, about 25
times as much as the power provided so far by Brake Energy Regeneration.

Generator delivering electrical brake power.

In the generator mode the two electric motors supply a lot of the
energy required to slow down the vehicle whenever necessary. Indeed,
the stopping power generated in this way is up to 3 metres/sec2
or, respectively, 0.3 g in a purely recuperative process,
significantly reducing the load acting on the mechanical brake system.

Sensotronic Brake Actuation (SBA) in the BMW Active Hybrid X6
may be used at any time without a direct mechanical connection between
the brake pedal and the hydraulic circuit. Pedal movement is recorded
by sensors and split up by a control unit into brake power generated
in a regenerating and
in a hydraulic process. At the same time
an integrated pedal force simulator generates the usual brake feeling
for the driver as an additional factor in this brake-by-wire solution.

The active brake servo builds up brake pressure with electrical
control according to the signals emitted by the control unit. To
ensure brake power assistance also in the all-electric mode, the BMW
ActiveHybrid X6 comes furthermore with an electrical under-pressure
pump replacing the vacuum pressure in the intake system of the
combustion engine on a conventional vehicle. A mechanical fallback
function, in turn, guarantees full operation of the brake system in
the event of a failure or deficiency in the electrical system, in
which case the stopping power required is generated by the hydraulic
system alone, like on a conventional vehicle.

The primary task of the SBA system is to split up the brake power
required
by the driver into a regenerating and a hydraulic brake
factor. Via the xDrive powertrain, the hybrid system in the BMW
ActiveHybrid X6 is able to
transmit brake forces to all four
wheels generated by the stopping power of the recuperative electric
motors. And whenever the stopping power required exceeds the level of
3 metres/sec2, the control unit builds up additional brake force
through the mechanical brake by means of the active brake servo.

In braking situations critical to driving stability the control unit
receives additional signals from the DSC Dynamic Stability Control,
intervening in the brakes and engine management to keep the vehicle
safely on course. This ensures safe braking manoeuvres under all
conditions, with all driving stability systems developing their
complete effect when required regardless of whether the stopping power
needed is generated electrically or hydraulically.

A further point is that all driving stability systems are tailored in
their
operation to the dynamic character of the Sports Activity
Coupé also on
the BMW ActiveHybrid X6. DTC Dynamic
Traction Control selected at the touch of a button, for example,
provides maximum traction and drive power
on loose surfaces such
as snow or sand thanks to its higher slip thresholds. And with the DTC
mode activated, the driver may opt for a particularly
sporting
style of motoring all the way to a controlled power slide in bends.

BMW xDrive: intelligent all-wheel drive for extra performance,
optimum driving stability and supreme traction.

The sports-oriented driving behaviour of the BMW ActiveHybrid X6
is
also attributable to xDrive all-wheel-drive technology.
Permanent all-wheel drive with electronically controlled, variable
distribution of drive power front-to-rear gives the BMW
ActiveHybrid X6, like all BMW X models, not only superior
traction, but also enhanced driving dynamics.

BMW xDrive qualifies as an intelligent all-wheel-drive system in
particular through the smooth division of drive power ensured by a
power divider with an electronically controlled multiple-plate clutch
feeding the appropriate level of power to the right axle with optimum
wheel contact and grip on the road.

Under normal conditions BMW xDrive spreads out drive power to the
front and rear axle in a 40:60 split, sensors consistently measuring
wheel slip
both front and rear. The system is able to vary the
balance of drive power within fractions of a second, BMW xDrive,
unlike conventional all-wheel-drive systems, thus looking ahead and
not only responding when a wheel is already spinning.

Benefiting from these abilities, BMW xDrive raises the driving
dynamics of
the BMW ActiveHybrid X6 to an even higher level
by recognising even the slightest tendency to over- or understeer
right from the start and taking appropriate counter-action.

EPS Electronic Power Steering for even greater driving comfort.

The BMW ActiveHybrid X6 is the first BMW X model to feature EPS
Electronic Power Steering. This allows active steering assistance both

when driving with the combustion engine and in the all-electric mode.

EPS provides optimum steering assistance under all conditions to give
the driver that special feeling so typical of the BMW brand. Another
advantage
is the further reduction of fuel consumption, EPS
significantly reducing the energy required for steering assistance
compared with conventional, hydraulic power steering, since Electronic
Power Steering only becomes active when steering assistance is
actually required or desired by the driver. So when driving straight
ahead in a straight line, for example, the electric motor does not
consume any energy whatsoever.

Electronic Power Steering on the BMW ActiveHybrid X6 comes
complete with fully integrated speed-related Servotronic steering
assistance, the reduction of assistance at high speeds ensuring not
only safe directional stability but also extremely precise steering
behaviour in bends as well as
the safe feeling at high speeds
again so characteristic of a BMW. At low speeds, on the other hand,
for example when parking, extra power
assistance significantly
reduces the steering forces required.

Liquid cooling for even greater performance on the

high-performance battery.

The high-voltage battery featured in the BMW ActiveHybrid X6
comes
in nickel-metal hydrid technology (NiMH). Capacity is 2.4
kWh, with 1.4 kWh available actively for practical use. Maximum
output, in turn, is 57 kW, with
the battery’s control unit
permanently determining the output level currently available as well
as the charge status of the battery.

The high-performance battery comes with its own liquid cooling system
incorporating a heat exchanger to cool the battery through the flow of

air from the outside and, additionally, through the cooling
circuit in the air conditioning. These two circuits are activated
either individually or
in combination with one another,
depending on current requirements,
the control unit selecting
the most effective and efficient cooling option
as a function of
ambient temperature and the temperature of the
high-voltage
storage unit.

Cooling by the air conditioning is activated by an appropriate switch
valve, with the electrical climate compressor being switched on
automatically whenever required. The interior and the high-voltage
battery being cooled separately of one another, cooling is far more
efficient than with a system using air cooling only, raising the
energy storage medium to a far higher level of performance and
retaining the hybrid functions longer in extreme weather and whenever
the driver prefers a very sporting style of motoring. Ultimately, this
gives BMW ActiveHybrid X6 an outstanding potential in driving
dynamics far superior to other hybrid vehicles in the market.

Intelligent energy management and integral safety concept.

Power electronics developed especially for BMW ActiveHybrid
technology ensures energy management on board the BMW
ActiveHybrid X6 both
very efficient and flexible in use.
The electronic control system consistently controls the distribution
of energy as a function of ambient conditions, the status of the
vehicle, and the demands made by the driver. The most important
incoming and control factor for the operating strategy chosen
is
the charge status of the high-performance battery saving the
electrical energy generated through recuperation.

The BMW ActiveHybrid X6 naturally complies in full with the
integral
safety concepts developed for hybrid vehicles by BMW.
With central
control functions being integrated both in the
power electronics and the energy battery, the system has the ideal
starting point for fulfilling all
kinds of international crash
test standards as well as the demanding internal standards of the BMW
Group, in particular guaranteeing the highest level of operating
safety on all components in the high-voltage on-board network.

Some of the features of this safety concept are the different colours
of
cables to avoid any confusion, the presentation of clear
safety warnings
and the all-round cover on the entire system
using extra-large insulation panels and newly developed connectors.

The high-voltage battery is housed in a high load-resistant steel
casing and
is fitted firmly inside the car, just above the rear
axle at an extremely safe point for the event of a collision. The
status of the storage modules is constantly supervised by integrated
safety electronics, the driver being informed immediately of any
malfunction and, wherever necessary, the entire system being
automatically discharged and deactivated.

In the event of a collision, the system is switched off automatically
within fractions of a second, the car’s central safety
electronics assessing the severity of an accident and ensuring a safe
operating mode as a function
of current, individual requirements.

Special hybrid drive Auto Start Stop function.

In city traffic the BMW ActiveHybrid X6 can be run in the
all-electric mode without using the combustion engine. A further
advantage is that the vehicle comes with a new generation of Auto
Start Stop technology featured here
for the first time. Tailored
specifically to the requirements of a hybrid car,
this new Auto
Start Stop function allows a much higher standard of comfort and is
available more often than the conventional system. Automatic
deactivation of the combustion engine at a road junction or at the
traffic lights does not in any way impair the driving experience, just
as the V8 power unit will start again immediately as soon as the
driver presses down the gas pedal.

BMW ActiveHybrid X6 provides the Auto Start Stop function
consistently
at all outside temperatures, no matter how cold or
how hot.

As long as the engine is switched off, the electric climate
compressor automatically maintains the climate and temperature desired
within the passenger compartment. All other electrically operated
functions are
also maintained, with the on-board network being
consistently supplied
with power from the high-voltage storage
unit. The only way to deactivate
the special hybrid Auto Start
Stop function is by choosing the manual gearshift mode on the
automatic transmission.

Additional displays informing the driver of the operating status and
efficiency of the hybrid system.

Operation of the hybrid system and current operating conditions are
presented clearly and understandably in the displays. The most
important information is shown in the central instrument cluster,
clearly separated according to the various operating modes. Further
information and technical explanations, in turn, are shown in the Info
Display in the centre console.

The drive displays are split up into a conventional rev counter for
the combustion engine and special displays for electric drive in the
lower part of the instrument cluster. Clear visual presentation of
these functions shows
the driver that the vehicle is ready to
go. The electric drive displays relevant
to the driver are the
charge status of the high-voltage storage unit, the recuperation
display, the support provided by the electric motors when accelerating
through their boost function, as well as the driving stages in the
all-electric mode. In the Control Display this information is
supplemented by additional data on current operating conditions and
the current flow of energy.

Specific set-up of the suspension and the lightweight brakes.

The chassis and suspension of the BMW Active Hybrid X6 is
largely the
same as the technology already featured on the BMW
X6 xDrive50i. The front axle is a double track arm configuration
ensuring excellent driving dynamics, superior motoring comfort and
smooth directional stability. The Integral IV rear axle has been
modified to reflect the specific characteristics of the hybrid model
in terms of weight distribution and drive power, guaranteeing absolute
supremacy on the road also ensured by self-levelling with air
suspension providing a consistent ride height also when carrying a
heavy load.

Lightweight brakes decelerate the BMW ActiveHybrid X6 by means
of
swing-calliper brake discs incorporating covers and pistons
made of aluminium. Brake disc diameter is 385 millimetres or
15.2” up front and
345 millimetres or 13.6” at the
rear. The entire brake system ensures a high standard of comfort in
applying the brakes and extreme resistance to fading.

Consistent lightweight engineering serves to reduce unsprung masses
and improve the vehicle’s driving comfort and agility.

Very attractive 19-inch light-alloy rims in V-spoke design come as
standard, and 20-inch light-alloy rims in aerodynamically optimised
Streamline design have been developed exclusively for the BMW
ActiveHybrid X6 as an option. In each case the tyres are runflat
tyres enabling the driver to continue to the workshop even after a
complete loss of pressure. And it almost goes without saying that the
BMW ActiveHybrid X6 comes as standard with a Tyre Defect
Indicator incorporating individual tyre pressure control.

Bodyshell and safety: intelligent lightweight construction, optimised
occupant safety.

Intelligent lightweight construction and a special structure for
maximum solidity also characterise the bodyshell of the BMW
ActiveHybrid X6. Apart from frontal and hip thorax airbags,
curtain head airbags at the side are also standard within the interior.

The BMW ActiveHybrid X6 comes with three-point inertia-reel seat
belts
on all seats featuring belt force limiters and belt latch
tensioners on the front seats. To protect the occupants from cervical
spine injury in the event of a collision at the rear, the front seats
feature crash-activated headrests, the
rear seats come as
standard with ISOFIX child seat fastenings.

All restraint systems are masterminded by central safety electronics,
rollover sensors serving to activate the curtain airbags and belt
latch tensioners in
the event of an impending rollover.

Featured as standard, dual bi-xenon headlights not only ensure
optimum illumination of the road ahead in the dark, but also provide a
daytime light function through their corona rings. The BMW
ActiveHybrid X6 furthermore comes as standard with a light and
rain sensor automatically controlling the vehicle’s lights and
screenwipers as required. Additional comfort at night
is
provided by the High Beam Assistant featured as part of
BMW ConnectedDrive.

Another feature available as an option is Adaptive Headlights
following the
road ahead in providing exact the right
illumination. This option comes complete with Bending Lights and
variable light distribution broadening
the light beam to provide
a wider range of vision as a function of road speed. As an option,
finally, information relevant to the driver may be projected on to the
windscreen via the Head-Up Display in a particularly ergonomic position.

    Het was beter omgekeerd geweest! Een volledig geruisloze 7 voor in ’t stad…

    @MRM:
    “Rijdt je iets sneller,…”. Ik bespeur hier inversie en een dikke taalfout! 😉

    Vreemd, ik had het gisterenavond al aangepast, maar blijkbaar werden de veranderingen niet opgeslagen.
    Anyway, nu zou het wel juist moeten zijn.
