The Buenos Aires Motorshow is proving to be an important event for GM as after the debut of the Chevrolet Cobalt Concept, the Detroit automaker released the first details on its second design study, the Colorado Rally Concept.

We first saw the Colorado as single-cab concept truck at the Bangkok International Auto Show earlier this year.

The Argentine study is a double-cab racing version of that concept fitted with a bevy of off-road accessories and components such as the front and rear bumper hooks and tow winches, an adjustable suspension that allows the driver to increase the ride height by 5 inches and special acrylic windows.

The Colorado Rally Concept is powered by a 2.8-liter turbo diesel engine coupled to an all-wheel drive system and rides on massive 18-inch machined aluminum wheels shod in 305/60 R18 tires.

The production version of the all-new Colorado in both single- and double-cab formats is slated to debut later this year.
