Je suis pas expert en mécanique mais quelqu'un pourrait dire si c'est comparable à la boîte DSG de VW.


MILFORD, Mich. – General Motors new Hydra-Matic 6T70 six-speed automatic transmission, an advanced transmission with clutch-to-clutch shift operation for front- and all-wheel drive vehicles, will debut in the all-new 2007 Saturn Aura midsize sedan. Co-developed with Ford Motor Co., the new six-speed joins the already announced Hydra-Matic six-speed rear-wheel drive family of automatics and Allison 1000 six-speed automatic as part of GM’s mission to produce 3 million six-speed automatics annually by 2010.

“The 6T70 offers the best of both worlds – the excitement of a performance transmission and the economy expected of an overdrive,” said Robert Vargo, assistant chief engineer, new front-wheel drive transmissions. “The joint development effort allowed both companies to maximize time and engineering talent to answer a common need for a fuel-efficient transmission that meets the performance needs of high-output, transverse-mount powertrains.”
