About Chevrolet Trailblazer
Being one of the most popular mid-size Sport Utility Vehicles (SUVs) in America, Chevrolet Trailblazer was produced by an American multinational corporation General Motors Company's automobile Chevrolet Division from 2001 to 2008 for the North American Market. Originally introduced to replace the Chevrolet Blazer, the Trailblazer was actually an upscale trim line of the Blazer and became a separate model until 2002. Due to large investment, the production of Trailblazer was ended in 2008 and it was replaced by Chevrolet Equinox and Chevrolet Traverse as EXT model in North America., though it won the North American Truck of the Year award.
Chevrolet Trailblazer made its debut in 2001 as a 2002 model and was available an extended-wheelbase version called the Trailblazer EXT that offered seven-passenger seating and class-leading cargo room. Featured an independent front suspension and a five-link rear suspension, Trailblazer came in three trim levels: base LS, luxury-themed LT and high-performance SS. During its lifetime, the Trailblazer was powered by a 4.2 L I6 rated at 302 hp and 330 lb-ft of torque, 5.3 L V8 producing 300 horsepower and 321 pound-feet of torque and a 6.0 L V8 making 391 hp and 400 lb-ft of torque. And all these engines sent power through 4-speed automatic transmission to rear wheels or four wheels.
