General Motors North America President Mark Reuss announced the launch the 2012 Cadillac XTS large luxury sedan for the Spring of 2012 and a compact luxury sports sedan codenamed ATS for the summer of 2012.
The XTS is based on the XTS Platinum Concept unveiled at the 2010 North American International Auto Show in Detroit. It will offer an advanced front-wheel drive and all-wheel drive system.
The Cadillac codenamed ATS is a rear-wheel drive luxury sports car to compete head-to-head with the BMW 3-Series, Mercedes-Benz C-Class and Audi A4 in the luxury market's largest segment.
Reuss also announced the eAssist light electrification feature on the 2012 Buick Regal will be a $2,000 option that delivers an estimated 25-percent improvement in fuel economy, giving Regal eAssist an EPA fuel economy rating of 36 mpg highway/25 mpg city. Regal with eAssist will start at $29,530, and Regal GS will start at $35,310; both prices include $860 in destination charges. The eAssist system is a $2,000 option on the Regal base model, mated to a 2.4L Ecotec engine. Buick will continue to offer the base model without eAssist as well as the 2.0L turbo.Regal eAssist, which goes on sale this fall, captures energy created during braking to charge a 115V lithium-ion battery that powers a 11-kW (15 horsepower) motor-generator, augmenting a 2.4L Ecotec four-cylinder engine. The eAssist system also allows the engine to shut down fuel delivery in certain deceleration conditions, saving additional fuel. Based on $4-per-gallon gasoline, the eAssist option on the Regal should pay for itself in about 3 1/2 years.
