The 2012 Buick Regal GS gets a direct-injected 2.0L turbocharged four under its hood and produces 270 hp as well as 295 lb-ft of torque from 2,400 rpm. Those are impressive numbers for such a small engine; in fact, it’s about as muscular as GM’s 3.6L V6. You also get a choice between 6-speed manual and automatic transmissions. When’s the last time you saw a clutch pedal in a Buick? I can’t remember either, but I’m glad one’s available now.
