2012 Buick Regal GS

The 2012 Regal GS is the turbocharged, high-output performance sedan enthusiasts have been waiting for from Buick. It boasts the best specific output ever in General Motors' storied history: 270 hp from a direct-injection, 2.0-liter Ecotec, which is better than the original estimate of 255 hp. The final rating breaks down to a heady 135 hp per liter, and torque is 295 lb-ft.
The Regal GS puts down max twist at 2,400 rpm and is estimated to sprint to 60 mph in 6.7 seconds.
Engineers worked on the chassis, adding Brembo brakes and springs that are 20 percent stiffer for a sportier drive. Ride height is lowered about 0.4 inch.
The cabin gets satin finishings and an athletic, flat-bottom steering wheel. In back, the standard exhaust pipes are swapped for quads, and there's a different spoiler and fascia in the rear. The car rolls on 19-inch wheels, with 20-inch wheels an option.
Visually, the changes up front include sabertooth-style vents, which differentiate the GS from other Regals. The car comes with a six-speed manual and gets 19 mpg in the city and 27 mpg in highway driving.
The GS starts at $35,310, including destination, when it arrives this fall. And yes, you can call it a Gran Sport.
Rather fast--because we sampled it on the road course at GM's proving ground in Milford, Mich., making minimal use of gears and maximum use of the revs. In this setting the car is a hoot. A true test comes later when we'll examine it on more conventional roads.
But on a closed course, the Regal GS is more than up for the task. It's strong off the line, the engine is potent and capable and it remains composed through tight corners in maneuvers. The steering is a little light but offers adequate feedback, and the suspension is tight without being abusive. Three settings--normal (or comfort), sport and GS--are offered, allowing the driver to tailor the experience to taste. In a nutshell, it feels a lot like a solid German sports sedan, which it is based on.
If someone asked you a few years ago whether you wanted a six-speed sports sedan with a turbo, 270-hp engine, you would jump on it. You'd be surprised it's a Buick. But it's 2011, and this car moves the needle literally and figuratively.
