The 2012 Buick Regal GS will be the most powerful model available and is powered by an Ecotec 2.0L direct-injected turbocharged four-cylinder engine. The 2.0L puts out 270 horsepower and 295 lb-ft of torque. The GS comes with a standard six-speed manual and reaches 0-60 mph in 6.7 seconds, while getting 28 mpg 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.”
To make the Regal GS even more fun to drive, GM has outfitted it with Interactive Drive Control System chassis technology. The driver selects among three operating modes that change the suspension settings, and steering sensitivity through the variable-effort steering system. “GS” mode optimizes the car for dynamic driving, tightening the suspension and steering response. “Standard,” or the default mode, is the setting for all-around use. “Sport” mode provides a level of performance between standard and GS modes.
The Buick Regal GS also rides lower than the other Regal models and comes with standard 19-inch alloy wheels.
