Performance is a strong point. When tromping on the gas, few TrailBlazer drivers are likely to realize the source of power is an inline-six-cylinder rather than a V-8. Not only is engine sound barely discernible (except when pushed really hard), but road noise is also virtually absent. Acceleration is undeniably stronger with the V-8, but it's not a dramatic difference., , On smooth surfaces, the four-wheel-drive TrailBlazer's ride is comparable to a car's. Its handling is a bit on the slow side, but the driver benefits from a satisfying steering feel., , Interior space is ample, and the seats are somewhat firm. The hard-working TrailBlazer competes enthusiastically against the Ford Explorer and other midsize rivals in passing power, ride comfort and handling.
