GM presented Crab Walk for the new Hummer electric truck. We’ll see if the Sierra AT4 could get a similar feature.

A 3.0-liter Duramax diesel is good for 277 hp and 460 lb-ft of torque, but it can’t tow more than the petrol mill. The powerplant is a good option, especially knowing Toyota Tundra and Ford Raptor are not going to use oil burners.
