SEMA: Chevy debuts two Colorado ZR2 concepts

Chevy has two new off-road toys to show off.

Chevrolet has unveiled two new concept vehicles at the SEMA Show in Las Vegas based on the company's Colorado mid-size pickup truck. Both concepts were designed with off-road use in mind.

Chevrolet Colorado ZR2 AEV conceptThe first SEMA concept, known as the Chevrolet Colorado ZR2 AEV, was created through a collaboration with off-road manufacturer American Expedition Vehicles. It's based on Colorado ZR2 equipped with a 2.8L Duramax diesel engine has been upgraded with an off-road specific suspension system, Multimatic DSSV Shocks, rear differential cover, AEV bumpers, underbody protection, snorkel, AEV beadlock wheels wrapped in 35-inch mud tires, LED auxiliary lighting and a Warn winch.

"ZR2 puts an exclamation point on Chevy's off-road engineering ability,” said AEV founder Dave Harriton. "Our collaboration taught us that Colorado makes a great platform for building an off-road truck that can take you as far out as you want to go, safely.”

Chevrolet Colorado ZR2 Race Development TruckThe ZR2 Race Development Truck was developed more as a desert runner than the AEV concept. As such, it includes a 3.6L V6 and a long-travel version of the ZR2's DSSV shocks. Other upgrades include a 1.5-inch body lift, 33-inch tires, rear shock skid plates, rear differential skid plate, steel driveshaft, wheel spacers and an off-road intake and exhaust system.

Chevy did not announce plans to put either truck into regular production.
