GM re-engineers pickups

More refined ride, higher-quality interiors, and greater efficiency are some of the highlights of the 2007 models.

General Motors' completely redesigned 2007 Chevrolet Silverado and GMC Sierra pickups are dramatically improved in virtually every area. Interiors have moved many steps upscale. Cabs are quieter. Ergonomics, ride dynamics, and safety are improved. There's class-leading hauling and towing capability.

GM is also touting them as the first full-size pickups capable of delivering more than 300 hp (224 kW) with better than 20 mpg fuel efficiency.
