There is some misunderstanding concerning the current Chevrolet Blazer and Trailblazer. The Trailblazer is a subcompact SUV, whereas the Blazer is a larger medium SUV. There is still some aesthetic and feature availability overlap, but not much else. Compared to the Trailblazer, the Blazer is a foot and a half longer has a spacious cabin and has more powerful engine options. The Trailblazer, on the other hand, has superior gas mileage and a cheaper initial price.
