The Chevrolet Silverado Cheyenne concept vehicle to be unveiled at the SEMA Show on Monday, Nov. 4, embraces the adage that less is more. Cheyenne was first introduced as a premium Chevy truck trim level in 1971. The name also appeared on a futuristic 2003 concept vehicle. The performance-oriented version of the all-new 2014 Silverado regular cab combines a reduced curb weight with the performance of the new 420-horsepower 6.2L V-8 for a strong power-to-weight ratio.

A lowered ride height, a rear stabilizer bar and Brembo carbon ceramic brakes complement the Cheyenne concept’s high-performance character with enhanced handling and braking capability.

The unique lightweight features built into the concept vehicle include carbon fiber replacements for the bumpers, tailgate and inner cargo box, shaving approximately 200 pounds from the 4,503 pounds base curb weight of a 5.3L-equipped Silverado regular cab with a 6’6" box.

Cheyenne designers matched the form of the lightweight components with their low-mass function. The carbon fiber front bumper includes racing-inspired ground effects styling complemented by carbon body-side ground effects while the carbon fiber tailgate incorporates a spoiler. The hood features a Camaro Z/28-inspired extractor vent.

The Camaro Z/28 Brembo carbon ceramic brakes save more weight because the carbon ceramic-matrix rotors are significantly lighter than conventional steel rotors. On the Camaro Z/28, for example, they save more than 20 pounds – and it saves un-sprung weight, too, which enhances driving performance with more immediate and direct handling. The truck rolls on charcoal-painted 19-inch Camaro Z/28 aluminum wheels and high-performance tires.

The Cheyenne diet removes the trailer hitch, spare tire, interior center console and some of the sound-deadening material. The truck also has a lightweight aluminum driveshaft and composite rear leaf springs.

The all-new EcoTec3 6.2L V-8 that powers the concept truck is rated at 420 horsepower and 460 lb-ft of torque – the most power in the light-duty truck segment. It’s unavailable in regular-production Silverado regular cab models, giving the Cheyenne a 65-horsepower and 77 lb-ft boost over the production 5.3L V-8. A Borla performance exhaust system adds an authoritative note to the 6.2L’s output.

What remains is the Silverado’s production six-speed automatic transmission, which features hill descent control, as well as fuel-saving electric power steering and StabiliTrak electronic stability control with hill start assist.
