  Chevrolet introduced the Trailblazer for the 2002 model year. The Trailblazer served as the brand's midsize SUV, replacing the S10 Blazer. The Trailblazer was not merely a revision of its predecessor, but a new vehicle from the ground up built on General Motors' new GTM360 truck platform. The Trailblazer initially offered only one engine choice, but by 2007, its second to last year of production, motor offerings had grown to three.
