GM Performance Division stuffed an LS2 6.0-liter V-8 under the hood of the Chevy TrailBlazer and lowered the suspension, then tuned and tested it at the Nurburgring. The 6.0-liter small-block makes 400 horses and 395 pound-feet in the SSR and Pontiac GTO. Of course, the SS package includes special styling and trim. Chevy estimates the TrailBlazer SS will do 0-60 mph in less than six seconds; not quite as quick as the 0-60 time Ford predicts for its SVT-built Adrenalin SportTrac. But the Chevy will beat the Ford to market -- it'll be available late this year only with an automatic transmission and your choice of rear- or four-wheel-drive.
