The 2015 Chevrolet Colorado mid-size pickup truck

Only an extended cab and crew cab (pictured here) configuration will be offered with the 2015 Colorado; the OEM decided the low volumes and low margins for regular cabs in its previous mid-size pickup model negated offering this spec option this time around.

The 2015 Colorado is 900 lbs. lighter than its full-size brother, the 2014 Silverado, from which much of its engineering derives.

Projector headlamps and grille shutters to improve vehicle aerodynamics are just some of the new exterior features on the Colorado.

The Colorado's rear bumper comes standard with GM's "CornerStep" feature.

The mid-size Colorado is part of GM's "three truck strategy" to offer a pickup in the heavy-duty, full-size, and now mid-size vehicle segments.

Onboard navigation is an option on the 2015 Colorado.

Doors and headliner area were "sculpted" to provide more interior space for the driver and passengers, especially in the crew cab configuration.

A 2.5 liter I-4 gasoline engine will come standard on the 2015 Colorado pickup.

An optional 3.6 liter V-6 gasoline engine will also be available for the new Colorado when it goes on sale in the fall of 2014.

A diesel option -- a 2.8 liter turbocharged Duramax to be precise -- will get added to the Colorado's engine mix for the 2016 model year, GM said.
