GM will be revealing two new hybrid pickup trucks at Chicago, banking on the idea that truck buyers will be as eager as everyone else to embrace the green-power phenomenon. The Sierra Hybrid pickup is the GMC version of the hybrid Chevy Silverado revealed at the LA Auto Show, and should be available for sale by the end of this year. The radical concept truck (pictured) is the Denali XT, built on a car-like unibody subframe rather than a conventional truck frame, which means it’ll behave more like the Holden Ute than a traditional pickup. Both trucks will use dual-mode hybrid gas-electric technology, alternating between straight electric power and an electric-assisted gas V8 (the Denali’s will be E85-capable, and the Sierra’s 6.0L can drop four cylinders when not under load, with the electric motor making up the difference in power). While another of Chevy’s big hybrids, the Tahoe, won the Green Car of Year Award at the LA Auto Show, don’t expect mpg ratings on these trucks to be mind-blowing.
