The Volkswagen Group is developing a 10-speed dual-clutch automatic gearbox, VW Group chief Martin Winterkorn confirmed at the Vienna Motor Symposium. He also said that the automaker is working on a high-performance diesel engine with 134bhp per litre. It’s believed that VW is developing the 10spd DSG transmission in response to more stringent CO2 emission rating legislation that will soon be implemented.
It will demand that automakers reduce their average fleet CO2 emissions by 2020 to 95g/km. He said that this diesel engine features “variable valve-train assembly, a high-pressure injection system at up to 3,000 bar and combined charging with the innovative e-booster [an electric turbocharger]”.
He added that by improving the combustion process and using a better lightweight design and having enhanced friction levels and thermal management, there could be a 15% boost in the efficiency of the petrol and diesel internal combustion engines.
In addition, VW is eager to promote natural gas technology, which Winterkorn describes as “environmentally friendly, economical and suitable for everyday use.”
He also said that this technology is already fully developed and that the market can already access these vehicles. He thinks that there should be more awareness in the public about how they can benefit from the use of natural gas engines.
He pointed out that for this endeavour to succeed, everyone including automakers, politicians and the fuel industry has to take part. Winterkorn is convinced that for the medium-term, plug-in technology is still the best and most efficient powertrain option.
