Vehicle Overview

GM says the Sierra 1500 Hybrid's gasoline V-8 and electric motors team up for an overall mileage improvement compared with the regular Sierra. The Sierra Hybrid is only available as a rear- or four-wheel-drive crew cab, both with a 6.0-liter V-8 and two electric transmission motors. Standard features include a trailering package, locking rear differential and side curtain airbags.
