Buick revealed the production version of the 2012 Regal GS, a sportier version of the Regal sport sedan that went on sale earlier this year.

Powered by a high-output, exclusive Ecotec 2.0L turbocharged engine mated to a six-speed manual transmission, the GS delivers an estimated 255 horsepower (190 kW) and 295 lb.-ft. of torque for a 0-60 mph performance of less than seven seconds (estimated).

Buick's Interactive Drive Control System is standard on the GS, allowing drivers to customize the driving experience by changing the suspension settings and steering sensitivity between three modes: standard, sport and GS.  

"Built on the performance foundation of the Regal, the Regal GS was designed as an even sportier expression of responsive performance and style," said John Schwegman, vice president of Buick marketing. "The driving experience is powerful and spirited; and the GS represents the next entry in Buick's product renaissance."  

The Regal GS goes on sale in the second half of 2011. Pricing has not yet been announced.
