Chevrolet has taken the wraps off the reborn Trailblazer SUV. The Trailblazer, which rides on the truck platform developed for the new Colorado pickup, is set to make its debut at the Bangkok motor show. Will it come to the United States? Chevy officials aren\'t saying yes, but they\'re not saying no, either. For foreign markets such as Thailand, the Trailblazer is set up with right-hand drive. Under the hood will be a choice of two turbodiesel four-cylinder engines. The 2.5-liter engine is rated at 150 hp and 250 lb-ft of torque. The optional 2.8-liter unit is rated at 180 hp and 346 lb-ft. Buyers have a choice of a five-speed manual or a six-speed automatic transmission. General Motors says it has developed other powertrains for the Trailblazer to be used in other markets. But it gave no details on Wednesday. The Trailblazer uses a body-on-frame construction with coil springs all around and a five-link rear suspension. The SUV is equipped with three rows of seats. The second and third rows fold flat to create a large cargo area. Chevrolet dropped the TrailBlazer from its U.S. lineup in 2008. It was replaced by the Traverse.
