GM just recently announced two of its most important new vehicles for the next few years.The Chevy Silverado and GMC Sierra are the best-selling full-size trucks in the country and more of these vehicles are still coming. 

The 2007 Chevy Silverado comes in three cab styles — regular, extended and Crew Cab — and three box lengths — short (5 feet 8 inches), standard (6 feet 6 inches) and long (8 feet).

There are seven different powerplants available for the Silverado, ranging from a 195-hp V-6 to a 367-hp V-8. Five of the six V-8s offered have cylinder deactivation for improved mileage. The top towing capacity will be 10,500 pounds.

Even more impressive than the advanced and economical engines is the much-improved interior. The Silverado LTZ features the same sophisticated dashboard and plush seats as the all-new Chevy Tahoe full-size SUV. That interior is one of the best GM has ever delivered.
