Well admit to a growing fondness for Chevrolets Cobalt small car, especially the one that debuted this year as the 2006 Cobalt SS Supercharged coupe.
With performance suspension and 205 hp and 200 lb-ft of torque on tap from a lightweight aluminum overhead-cam 2.0-liter four-cylinder, the supercharged model is good. But if you really want something to get charged up about, stand by for Stage 1 and Stage 2 upgrades for the SS Supercharged (and Saturn Ion Red Line) due in early 2006.
Stage 1 adds revised fuel injectors and new engine calibration to pick up another 20 hp; Stage 2 increases boost via a smaller supercharger pulley (along with another engine recalibration job) to amp up the torque by about 20 lb-ft. The packages can be readily installed by the owner. Pricing will be announced in November at the Specialty Equipment Market Association show in Las Vegas.
Weve driven the base supercharged cars, along with the Stage 1 and 2 upgrades, and while the Stage 1 noticeably increases power, the added torque in the Stage 2 package is worth the extra cost and effort. The added boost provides a substantial increase in power, especially at the low- and mid-rpm range where base and Stage 1 models need a downshift to prevent running short of breath.
Need more incentive? GM Performance hoss John Heinricy says he expects a 20 percent power boost from the Stage 2 kit when all is said and done. Thats about 246 hp and 240 lb-ft, if youre keeping score.
