The official performance and fuel economy numbers on the 2012 Buick Regal GS are out. When GM revealed the Buick’s sports sedan in production trim at the Detroit Motor Show this past January, the company estimated that the Regal GS was good for 255HP and a 0-60mph time of less than 7 seconds.
Now GM announced that the Regal GS’ 2.0-liter direct-injected turbocharged four-cylinder engine has been SAE-certified to deliver 270 horsepower (201kW) and 295 lb.-ft. of torque (400Nm) fat 2,400 rpm or an estimated 0-60 mph performance of 6.7 seconds, or 0.9 seconds slower than the car’s European sibling, the Opel Insignia OPC that features a 325HP V6 and AWD.
Power in the North American model is channeled to the front-wheels only through a six-speed manual gearbox, with GM stating that the Regal GS gets an estimated fuel economy of 28 mpg (8.4 lt/100km) on the highway
“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,” said 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 V-6s, while delivering the fuel economy you’d expect of a four-cylinder,” Anderson added.
The new 2012 Regal GS will go on sale in the States this fall with prices to be announced closer to launch.
