Chevrolet Colorado ZR2 Concept brings diesel off-road focus to Detroit
Chevrolet’s Colorado ZR2 Concept, powered by the 2.8-litre Duramax diesel, debuted at the 2015 Detroit show with a raft of off-road upgrades and rugged styling.
Chevrolet took the covers off the Colorado ZR2 Concept at the 2015 North American International Auto Show, signalling its interest in a diesel-powered, off-road-focused midsize pickup. The ZR2 Concept builds on the existing Colorado platform but introduces a range of modifications aimed at buyers seeking greater off-road capability and a tougher appearance.
The concept’s 2.8-litre Duramax turbo-diesel four-cylinder, already seen in Chevrolet’s global markets, produces 181 horsepower at 3,400 rpm and 369 lb-ft of torque at 2,000 rpm. Power is sent through a six-speed automatic gearbox. This engine choice positions the ZR2 as a direct response to the growing interest in diesel pickups, but in the midsize segment rather than head-to-head with full-size rivals like the Ram 1500 EcoDiesel.
Chevrolet has equipped the ZR2 Concept with a two-inch suspension lift, new front control arms, and mono-tube coil-over shocks. Electronic-locking differentials front and rear, along with skid plates, aim to improve traction and durability over rough terrain. The approach angle is rated at 30.7 degrees and the departure angle at 22.7 degrees, both improvements over the Colorado Z71’s 25 and 21 degrees respectively.
Off-road styling and interior details
The ZR2 Concept’s exterior features a revised grille, aluminium tow hooks, an integrated winch, a power dome bonnet, custom fender flares, and 18-inch bead lock-style aluminium wheels with off-road tyres. These changes give the truck a more aggressive stance and underline its off-road intent.
Inside, Chevrolet has embroidered ZR2 logos on the headrests and added custom floor liners. A dashboard inclinometer provides the driver with information on the vehicle’s tilt angle, useful for off-road manoeuvres.
Position in Chevrolet’s range
The ZR2 Concept sits above the existing Colorado Z71 in terms of off-road hardware and intent. While Chevrolet has not confirmed production plans, the concept tests the waters for a more specialised midsize pickup. Its combination of diesel power and serious off-road equipment is aimed at buyers who want more than the standard Z71 offers, but do not want to step up to a full-size truck.
