De twee nieuwe motoren zijn de 1.2-liter TSI en de 1.6 liter TDI. De 1.2 TSI heeft dankzij een turbo en directe brandstofinjectie 105 pk en een maximaal koppel van 175 Nm. De 1.6 TDI is beschikbaar met verschillende vermogensoutputs. De eerste is een 1.6 TDI met 75 pk die enkel voor de Volkswagen Polo beschikbaar wordt, de motor kan echter ook met 90 of 105 pk gekocht worden. Deze laatste twee zijn beschikbaar voor zowel de nieuwe Golf als de nieuwe Polo.
Volgens Volkswagen wordt de 1.6 TDI de basis voor alle toekomstige viercilinder diesels binnen de groep, de motor verbruikt nog minder en voldoet uiteraard aan de EU5 emissienormen. Ook over elektrische aandrijflijnen werd gesproken, maar Volkswagen gelooft dat er nog veel bespaard kan worden met de benzinemotor.
Volkswagen presents its newest engine generation at the 30th Vienna Engine Symposium
Maximum dynamics and minimum fuel consumption also for the newest 1.2 litre TSI and 1.6 litre TDI engines
Downsizing is consistently adapted to volume models
Wolfsburg, 08 May 2009 – Highly efficient and at the same time low in emissions, the newly developed TSI engines caused quite a stir in previous years at the Vienna Engine Symposium. This year, Volkswagen will again emphasise the downsizing approach at the high-calibre conference of TSI and TDI engines and will present two new engines. Volkswagen transfers the pioneering technologies now to even smaller displacements with the 1.2 l TSI and the 1.6 l TDI.
Dr Jens Hadler, Head of Engine Development at Volkswagen, explains: “The potential of internal combustion engines is far from exhausted”. Both engines impressively show how Volkswagen reduces the CO2 emissions and the fuel consumption and that to fungible costs. Downsizing is rigorously being developed in the volume segments with the 1.2 TSI and the 1.6 TDI.”
Volkswagen completes its TSI engine family with the powerful 1.2 litre 77 kW / 105 PS TSI engine. Petrol direct injection is combined with a turbocharger to deliver convincing performance levels and torque curve despite its smaller displacement. Thus, the maximum torque of 175 newton metres is already available at a low engine speed of 1500 rpm.
The continued development of the engine technology of the small but powerful engine family uses rigorous friction optimisation and lightweight construction. The engine with an aluminium crankcase and a completely newly developed combustion process combines pulling power, high fuel economy and low emissions in an ideal manner for the volume engines of Volkswagen. These superiorities have already been rewarded in the 1.4 litre TSI family member which has been awarded the famous “Engine of the Year” Award three years in a row.
The new 1.6 litre TDI engine was presented at the Engine Symposium by Falko Rudolph, Head of Volkswagen Diesel Engine Development, as “an engine as universal as the Golf”. The new entry-level engine for the Polo and the Golf convinces with good driving performance while at the same time keeping fuel consumption low. It will be available in the 55 kW / 75 PS (only Polo), 66 kW / 90 PS and 77 kW / 105 PS options. Thanks to its modular structure, the 1.6 litre TDI engine will serve as a basis for all future four-cylinder diesel engines of Volkswagen. It meets the EU 5 exhaust emission standard and is perfectly equipped with regard to future emissions requirements.
The essential development goals of the new 1.6 litre TDI such as the reduction of fuel consumption were achieved, among other things, through the reduction of friction. Besides the characteristics of economy and performance, importance was placed on low CO2 emission which was achieved through the diesel particulate filter with an upstream oxidation catalytic converter located close to the engine. Both engines, the 1.2 TSI and the 1.6 TDI will be available to order for the new Polo and the Golf this year.
For decades, the leading engineers of engine and gearbox development meet at the Vienna Engine Symposium to present their newest developments and to give a perspective on future trends.
