Theres no debate. TrailBlazer is one powerful mid-size SUV. A 275 hp Vortec 4200 in-line 6-cylinder engine generates more standard horsepower than any other V6, or V8, in its class. And gives you a towing capacity of 2767 kg (6100 lb.) on 4x4 models. Hydroformed-steel side rails set a new standard for lightness and strength. Yet with 65/35 split second-row seating and wide-opening liftgate, TrailBlazer has the flexibility to take on adventure after adventure.
