This Chevrolet Colorado Rally Concept made an appearance in the 5th International Motor Show in Buenos Aires, Argentina. A follow up of the Colorado Show Truck revealed at the recent Bangkok Motor Show, the Rally Concept and its predecessor is a preview of GM’s upcoming one-tonne pick-up challenger. But while the BKK Show Truck was king cab, this is a dressed up double-cab.

Equipped with 4WD and 18-inch “double ended” aluminum rims with 305/60 tyres, the Colorado Rally Concept also comes with high performance shock absorbers, height adjustable suspension and integrated winch on front and rear bumpers, with 23-metre long reinforced steel cables. The unique tailgate with cutouts is to improve aerodynamics and reduce weight.

Inside, the basic dash architecture is similar to the Bangkok truck, but with redesigned elements that go well with the “extreme” overall theme. Power comes from a 2.8-litre turbodiesel engine, Chevy says, although the main thing they want to show off for now is the styling.

Very macho. Gallery after the jump.
