Chevrolet revealed a high-performance Silverado Cheyenne pickup truck concept today at the opening of the SEMA Show in Las Vegas.
First appearing as a premium trim level of the Chevrolet pickup in 1971, the Cheyenne name reappeared on a futuristic 2003 concept vehicle.
The new Cheyenne Concept is based on a new 2014 Silverado regular cab model with standard 6'6" box but it features a combination of reduced weight and substantially increased power to give it a highly favourable power-to-weight ratio.
Unique light-weighting features built into the concept vehicle include carbon-fibre bumpers, tailgate and inner cargo box, cutting about 90 kg from its original 2042-kg mass.
The carbon-fibre front bumper includes racing-inspired ground effects styling complemented by carbon body-side ground effects and the carbon-fibre tailgate incorporates a spoiler, while the hood features a Camaro Z/28-inspired extractor vent.
Other light-weighting tactics include removal of the trailer hitch, spare tire, interior centre console and some sound-deadening material, as well as use of a lightweight aluminum driveshaft and composite rear leaf springs.
Inside, there are Recaro sport seats and a flat-bottom steering wheel, similar to the one offered in the Camaro ZL1.
Power comes from a 6.2-litre EcoTec3 V-8 engine rated at 420 horsepower and 460 lb-ft of torque – 65 horsepower and 77 lb-ft more than the top-rated 5.3 litre V-8 available in the production model. A Borla performance exhaust system is said to add an authoritative note to the 6.2L's output.
In addition to less weight and more power, the concept features a lowered ride height, a rear anti-roll bar bar and Brembo carbon ceramic brakes to enhance handling and braking capability.
The truck rolls on charcoal-painted 19-inch Camaro Z/28 aluminum wheels and high-performance tires.
"It is only a concept right now, but we are continually exploring new ways to give Silverado customers more," said Chris Perry, vice president of Chevrolet marketing in the U.S.
Which means, don't be surprised to see a production version of the Cheyenne to do battle with Ford's 2014 F-150 Tremor in the near future.
