Logan, OH — On a recent validation drive of the new, 2011 Chevrolet Silverado Heavy–Duty Trucks, engineer Brent Deep towed a 20,000–pound trailer(1) for 245 miles along I–70 between Denver and Grand Junction, Colorado.
Deep relied on the Silverado’s new, smart exhaust brake system to slow the truck/trailer combination on descents, helping prove the new system is suitable for the most demanding conditions. It was a drive across the heart of the Rocky Mountains and some of the interstate system’s steepest grades, with altitudes ranging from Denver’s approximately 5,000 feet to more than 11,100 feet at the Eisenhower Tunnel.
“It takes some courage to leave your foot off the brake, but the Silverado’s Duramax engine and Allison transmission perform the task with smoothness and confidence that really impresses,” said Deep. “Better still, the exhaust brake system can help extend brake pad life and help avoid overheating the brakes on long descents.” The available new Exhaust Brake System’ works with the Allison transmission’s Tow Haul Mode and Automatic Grade Braking features, reducing the amount of conventional braking needed while towing or traveling downhill. They go on sale this summer.
The new 2011 Chevy Silverado HD 6.6L Duramax turbo–diesel V8 delivers 397 horsepower and 765 lb–ft. of torque making it the most powerful heavy–duty on the planet, better than Ford or Dodge. It delivers more power and even better fuel economy.
The Silverado heavy–duty lineup is broader than ever, with 10 2500HD models and 14 single and dual–rear–wheel 3500HD models – including a new 3500HD Crew Cab with a 6.5 foot cargo box. WT, LT and LTZ trim levels are offered. All models bring greater capability, improved ride and a greater feeling of driver control.

- Standard small–block 6.0L gas V8 delivers 360 hp.
- Diesel power complemented by up to 11 percent improved highway fuel economy and up to 63 percent reduced NOx emissions. (Based on GM testing.)

“The new Chevy trucks are built to take on a tough job, but they’re also designed for comfort, good looks and great handling,” said Jeff Wood, President of Don Wood Automotive (Chevrolet, Buick, Cadillac), Logan, Ohio.
Outside, the 2011 Silverado 2500HD and 3500HD models are distinguished by a power dome–style hood as well as a new grille and full–width chrome steel front bumper. A new lineup of 17, 18 and 20–inch wheel/tire combinations is featured too (20–inch polished forged aluminum wheels are available on 2500HD).
Designers and engineers left almost no bolt unturned during the comprehensive redesign of the trucks.
1 Requires fifth–wheel hitch and Regular Cab Model. Maximum trailer weight ratings are calculated assuming a base vehicle, except for any options necessary to achieve the rating, plus driver. The weight of other optional equipment, passengers and cargo will reduce the maximum trailer weight your vehicle can tow.
