One of Bertel and my favorite Chinese car blogs, ChinaCarNews, has been reporting since October than the next-generation of MG/Roewe midsized sedans would be based on GM’s Global Midsized (Epsilon II) chassis (which underpins Buick LaCrosse/Regal and the new Chevy Malibu), and now the rest of the media appears to be catching up. From InsideLine to Autocar, everyone’s running with the story that MG/Roewe, which is owned by GM’s main Chinese partner SAIC, is working on an Epsi II-based MG7 for launch in the 2015 timeframe. According to InsideLine

[In 2015], the MG7/Roewe 750 sedan replacement appears some 15 years after the debut of the Rover 75 they’re based on. A coupelike four-door, it uses GM’s Epsilon platform and will be powered by 2.0 and 2.4 four-cylinder gasoline engines and a 1.9 diesel, all with dual-clutch transmissions.

GM and SAIC signed a Memorandum Of Understanding back in October [.DOC file here], which included the provision that, in addition to developing a next-gen electric architecture,

SAIC and GM anticipate sharing an additional vehicle architecture and powertrain application in an effort to help reduce development costs and benefit from economies of scale.

This could explain MG/Roewe’s rumored use of the Epsilon II chassis, but for the moment GM dismisses these rumors as “speculation.” And no wonder: even GM hasn’t announced when it will offer a dual-clutch transmission in its Global Midsized platform. Chances are, The General will want to offer that combination before its Chinese partners use it to beef up its MG/Roewe brands, which have been in product rehab for some time now.
