The Buick Regal GS unveiled a stick-shift sedan at the Detroit Auto Show that is capable of reaching 60 mph in less than six seconds. Jim Federico, vehicle line executive for global mid-sized architecture at General Motors Co., said that he is convinced that launching a vehicle such as this would upgrade Buick's performance image immediately.
The GS, which stands for Grand Sport, was a badge worn by Buick's performance cars in the 1960s and '70s. The 2011 Regal is based on GM's global mid-sized front-drive platform and is essentially a rebadged Opel Insignia.
Almost all of the Regal GS performance upgrades have been adopted from the Insignia OPC, which is currently sold in Europe. The Regal will be available starting in the second quarter while the Regal GS production vehicle is expected next year.
Instead of rear drive and a V-8, the Regal GS has a turbocharged four-cylinder engine generating an estimated 255 hp and 295 pounds-feet of torque.
The Regal GS has an adaptive all-wheel-drive system that includes an electric limited slip rear differential. The GS concept is equipped with Brembo brakes that have 14 x 1.2-inch rotors; four-piston, high-strength aluminum calipers; and performance high-speed pads.
In this concept, the driver can select one of three operating modes -- normal, sport or GS -- to change suspension settings, throttle response, shift pattern and steering sensitivity.
