Renault is reviving the Gordini name for high-performance models

They don't sell Renaults in the United States anymore, but it's worth noting that the French automaker is reviving the Gordini name for high-performance versions of the Twingo and the Clio. The name pays homage to Amedee Gordini, a mechanical whiz known as "the sorcerer" for taking production-car engines and making them competitive on the great racetracks of Europe. The Gordini versions of the Twingo and the Clio will wear the trademark light blue paint with a pair of white stripes running from nose to tail and centered over the driver.

Buick plans to add a crossover in 2010, a plug-in hybrid in 2011

Buick's lineup is growing--it's getting a new five-passenger crossover in 2010, with a plug-in hybrid following in 2011. The yet-to-be-named vehicle will be smaller than the Enclave and uses a different version of the platform that underpins the GMC Terrain and the Chevrolet Equinox. The move signals General Motors' renewed commitment to its venerable Buick brand, fortifying it with cutting-edge technology and fresh sheetmetal as the company tries to be competitive with four core brands.
