GM hints at CT6-based Buick

Product chief Mark Reuss hints that a Buck production model based on the Omega platform is currently under consideration.

A General Motors top executive has hinted that the company is considering building a Buick model that borrows the Cadillac CT6's platform.

Speculation surrounding a flagship Buick sedan based on GM's Omega architecture has continued to grow since the company revealed the Avenir concept at the Detroit auto show. The sedan was presented in an all-wheel-drive configuration powered by a V6 engine, matching the CT6's top trim levels.

GM product chief Mark Reuss has confirmed that the Omega platform could be used to underpin a new flagship Buick, but such a model has not yet officially received a green light, according to an interview with Automotive News.

"We're working on that," he added.

The North American CT6 will be built in Hamtramck, Michigan, while a Chinese-spec variant will be produced locally. GM expects Cadillac sales to double in China by the end of the year, however Buick is still GM's leading brand in the country -- outselling Chevrolet and beating Cadillac by a wide margin. An Omega-based Buick is consequently viewed as a particularly attractive proposition as GM continues to battle for market share against aggressive rivals in China.

Reuss suggests such a model may not use the exact same platform configuration as the CT6, however the architecture is said to be "very flexible" for adaptation. The company is already working on a new CT-badged model with a longer wheelbase than the CT6, potentially serving as an even better stablemate for a stretched Buick flagship aimed at Chinese buyers.
