The 2012 Buick Regal GS is set to hit dealerships this fall, but that means engineers still have time to fine-tune the vehicle before it arrives in showrooms across the country. What better way to do that than to take the Regal GS to the automaker's Milford Proving Grounds? This Michigan road course is a twisting, turning stretch of asphalt that allows engineers to really put a vehicle through its paces.
The hi-po Regal GS is powered by a direct-injected 2.0-liter turbocharged Ecotec four-banger, which pumps out 270 horsepower and 295 pound-feet of torque. That's enough horses to coax the sedan from 0 to 60 in 6.7 seconds, according to General Motors estimates. A few more notes about those power figures: First, when the Regal GS was first announced, we were only promised 255 horses, so 270 is a very welcome figure.
Second, the Regal GS and its 2.0L turbo boasts more torque than the larger 3.6-liter Pentastar V6, which produces 260 pound-feet in the Chrysler 200, and the 2.0-liter Turbo in the Hyundai Sonata, which is rated at 269 pound-feet of twist (to be fair, the latter two have never claimed to be sport sedans). What else does it beat? The list includes the Acura TSX V6, Audi A4, Lexus IS250 and the Volvo S60 T5. Plus, 95 percent of that peak torque is available from 2,300 to 4,900 rpm.
It's also worth mentioning that, with 135 horsepower per liter, the new boosted Ecotec boasts the highest specific power output of any engine in GM's history. It's also the most power-dense rating the SAE has ever officially recognized. That's impressive stuff.
Now we bet you're ready to watch a Buick test driver push the 2012 Regal GS around the track. Stop reading and click past the jump for the clip. Also, be sure to take a look at the full press release for more information on this new, sporty Regal.
