The Volkswagen Group announced some new powertrain details at this year's annual Vienna Motor Symposium. We've got some new engines and a new gearbox to look forward to in future Volkswagen Group cars. Here's the low down.

New ten-speed DSG gearbox

VW is jumping from the current seven-speed count straight up to ten ratios for their next generation DSG gearbox. The most gears in a Volkswagen right now would be eight - but that gearbox is not a DSG. The eight ratios are provided by an Aisin torque converter automatic gearbox, installed in cars like the Volkswagen Touareg.

A jump to ten would one-up rivals like Mercedes-Benz who have announced nine-speed automatics, but Volkswagen says the primary aim is to increase efficiency of future cars by up to 15% by 2020. The new gearbox family would be installed in both transverse or longitudinal engine bays, and will be able to take torque of up to 500 Nm.

New 2.0 litre TDI bi-turbo diesel engine

The next generation Volkswagen Passat will get the option for a twin-turbocharged 2.0 litre TDI diesel engine producing up to 236 horsepower, impressive output figures for a turbodiesel engine of that size. Volkswagen's single turbo TDI currently tops out at 181 horsepower.

New 2.0 litre TSI petrol engine

We sorta already knew this thanks to all the concept cars that the group have been putting out lately. The group's 2.0 litre TSI engine will be pushed to produce about 400 horsepower in its next iteration. We've previously seen a 420 PS version in the Audi TT quattro sport concept and a 400 PS version in the Golf R 400 Concept.

New 1.0 litre TSI three-cylinder petrol engine

The next step for the EA211 engine family will be a three-cylinder TSI engine with 1.0 litres of displacement, which will first find its way into the Polo facelift and the Golf. The engine will have three power ratings - the Polo will get a 94 hp / 160 Nm version and a 109 hp / 200 Nm version, while the Golf will get a 114 hp / 200 Nm version. Looks like this new engine will replace the 1.2 TSI.
