SEMA 2010: Chevy Unveils Custom Z71 Silverado 2500 HD and 3500 HD Race Car Hauler


While the numerous custom Camaros and wild modified Corvettes might be stealing the spotlight over at Chevy‘s SEMA booth, let’s not forget about the working man’s Silverado HD.

For 2011 Chevy revamped the trucks with an all new frame and a new Duramax engine. Now the team at Chevrolet is looking to offer even more to Silverado HD customers with a long list of accessories. On display at SEMA is a Silverado 2500 HD Z71 with a Switchblade Silver paint job and custom Z71 graphics. It’s also got custom Corvette Competition Gray-painted 20-inch wheels, as well as a body color grille, tonneau cover, a hitch-mounted winch, and side steps in a matching Corvette Gray. Inside, the truck gets two DVD players mounted int he headrests, and the truck is equipped with wi-fi.

Parked next to the 2500 is an even more massive 3500 model, equipped to pull a race car – which should be a joke for the big Chevy truck with its tow rating maxing out at 21,700 lbs. It gets custom racing graphics, 17-inch wheels, chrome hood louvers, a custom grille insert, chrome fuel door and trailering mirrors.

Redesigned for 2011, the Silverado heavy-duty lineup is broader than ever, with 10 2500HD models and eight single- and dual-rear-wheel 3500HD models. In the Chevrolet display at the SEMA show, a new, accessorized 2500HD Extended Cab Z71 equipped with the new 6.6L Duramax turbo-diesel engine Allison 1000 six-speed automatic transmission demonstrated the personalization possibilities of the new HD lineup.

All 2011 Silverado HD models bring greater capability, improved ride and handling and a greater feeling of driver control. Highlights include:

A new lineup of 17-, 18- and 20-inch wheel/tire combinations is featured, too, and the 2500HD SEMA show vehicle displays 20-inch wheels that are available through Chevrolet dealers, but painted Corvette Competition Gray for the show vehicle.

The 2011 Chevrolet Silverado 3500HD was designed for effortless towing and hauling. It looks great doing it, too – especially when it is connected to a Chevy race car and trailer. Chevrolet highlighted the capabilities of the new HD truck at the SEMA show by pairing it with a race car mounted on an open trailer and hooked to a Silverado 3500HD Crew Cab Dually.

“A Chevy race car being towed by a new Silverado HD truck is a combination any enthusiast would love to call his own,” said Paul Arnone, lead designer. “The 2011 Silverado 3500HD can tow up to 21,700 pounds, so a race car on an open trailer is no sweat for this truck.”

Maximum towing capability is achieved with the improved Duramax 6.6L turbo-diesel engine and that’s exactly what’s under the hood of the display vehicle. It’s paired with a revised version of the Allison 1000 six-speed automatic for a powertrain combination that is more powerful yet more fuel-efficient than the one it replaces.

No powertrain modifications were made to the display vehicle, but its exterior and interior wear a number of Chevrolet Accessories and other aftermarket parts, as well as a few custom touches developed by Chevrolet designers. They reflect the personalization many customers perform to enhance the style, comfort and capabilities of their truck. Highlights include a full-width tool box and, on the inside, dual DVD headrests.

“Just about every unique part or system on the show vehicle is available through Chevrolet dealers or via licensed aftermarket manufacturers,” said Arnone. “It is a truck designed for the greatest work capability, but it does so with exceptional comfort and flair.”
