At the 2010 Los Angeles auto show, Buick introduced us to the 2012 Regal GS, the upcoming four-door that will be the highest-performance version of the Opel-cum-Buick. We weren’t thrilled that the turbocharged 2.0-liter four-cylinder engine made just 255 hp and 295 lb-ft of torque; for a car Buick is promoting as a sport sedan, it’s not impressive to be outgunned in horsepower by the higher-output versions of the Hyundai Sonata, Toyota Camry, Honda Accord, and Nissan Altima. That won’t be the case any longer, at least, as official SAE testing now rates the Buick’s engine at 270 hp. (Torque remains at an ample 295 lb-ft. That should be plenty for the GS’s front wheels to handle.)

The torque peak occurs at 2400 rpm, and 95 percent of the peak twist is available between 2300 and 4900 rpm. Buick estimates the GS will launch itself from 0-to-60 mph in around 6.7 seconds. We feel this might be a tad conservative since a 220-hp Buick Regal Turbo we tested did the deed in just 6.8 seconds. Still, the extra power probably won’t propel the Buick with enough force to match the 5.6-second 0-to-60 time we recorded in a six-cylinder Accord. When the Regal GS arrives in dealerships this fall, it will pack a six-speed manual transmission, and the manufacturer promises a six-speed automatic will come some time later.
