The Chevrolet Suburban HD Z71 is the culmination of a "what if" exercise that melds the popular Suburban 2500HD with the popular Z71 off-road package – a combination not currently offered by the factory – and partners it with a new, fuel-saving smaller-displacement diesel engine.

The concept uses many production parts, including the front-end assembly from Chevy's HD trucks, along with some unique custom touches – including rear wheel flares that pick up the styling cues of the front end. Power is generated by a new 4.5L diesel engine that gives this off-road-ready Suburban power, poise and efficiency.
