Chevrolet's toughest, most- refined midsize sport utility vehicle, the TrailBlazer, made its global debut today at the opening of the Dubai International Motor Show in the Middle East. The robust seven-seat show vehicle previews Chevrolet's latest SUV offering, which will be sold around the world, beginning with Thailand in early 2012. The new-generation TrailBlazer combines the hauling and towing capability of a body-on-frame SUV with the ride comfort and efficiency of a crossover. Developed in tandem with the all-new Chevrolet Colorado pickup by GM do Brasil, it shares the same architecture as its truck sibling, with a chassis tuned to combine heavy-duty off-road capability with refined city driving. The show vehicle features an all-wheel-drive system and is powered by GM's new 2.8-liter Duramax turbo-diesel engine, which features a variable-geometry turbocharger for an optimal combination of performance and fuel economy.
