The all-new 2012 Buick Regal GS arrives this fall and will pack a serious punch. The GS has ow officially been rated at 270-hp and 295 lb-ft of torque and achieves a 0-60 mph time of 6.7 seconds. For the record, that's 15 more horsepower than originally claimed.

The GS will be powered exclusively by a 2.0-liter direct-injected turbocharged four-cylinder engine that boasts more torque than the Acura TSX V6, Audi A4 Sport, Lexus IS 250 or Volvo S60 T5.

"The Regal GS 2.0L turbo delivers the highest specific output of any production engine GM has ever offered, and at 135 hp per liter is the most power dense engine ever certified by SAE," explained Mike Anderson, Ecotec global chief engineer and program manager. "We've been combining direct injection and variable valve timing with boosted engines since 2006, and there's no question the Regal GS turbo has the responsiveness and acceleration of some V6s, while delivering the fuel economy you'd expect of a four-cylinder."

This very special Ecotec engine will include direct injection, continuously variable valve timing, a forged steel crankshaft, a twin scroll turbocharger and a highly efficient intercooler system. The 295 lb-ft of torque is available from as low as 2400 rpm and 95 percent of the torque is available between 2300 and 4900 rpm.
