Silverado Cheyenne Concept: Mini Mass, Max Performance

The Chevrolet Silverado Cheyenne concept vehicle unveiled at the SEMA Show on November 4, embraces the adage that less is more. The performance-oriented version of the all-new 2014 Silverado regular cab combines a reduced curb weight with the performance of the new 420 hp 6.2 l V-8 for a strong power-to-weight ratio and exhilarating performance.

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 90 kg from the 2,050 kg base curb weight of a 5.3 l-equipped Silverado regular cab with a 2 m 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 9 kg – and it saves unsprung 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.
Inside, the Cheyenne’s performance theme is conveyed with Recaro sport seats and a flat-bottom steering wheel, similar to the steering wheel offered in the Camaro ZL1. Available safety features, including lane departure warning, front and rear park assist and a rear-vision camera, enhance safety without detracting from the truck’s performance.
