LAS VEGAS (November 4, 2013) – The Chevrolet Silverado Cheyenne concept vehicle unveiled at the SEMA Show on Monday, Nov. 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-horsepower 6.2L 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 Cheyenne concept explores the performance possibilities of the all-new Silverado, which is already built on a mass-efficient layout and delivers a greater balance of performance and efficiency than any other full-size truck in Chevrolet’s history,” said Chris Perry, vice president of Chevrolet marketing.

The unique lightweight features built into the concept vehicle include carbon fibre replacements for the bumpers, tailgate and inner cargo box, shaving approximately 90 kg (200 pounds) from the 2,042 kg (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 fibre front bumper includes racing-inspired ground effects styling complemented by carbon body-side ground effects while the carbon fibre 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 (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 centre console and some of the sound-deadening material. The truck also has a lightweight aluminum driveshaft and composite rear leaf springs.

“Lightweighting is a time-honored method of making the most of a vehicle’s performance which Chevrolet has demonstrated time and again with vehicles like the original 2001 Corvette Z06 and the 2014 Camaro Z/28,” said Perry. “And like those vehicles, the Cheyenne complements its lower weight with more horsepower.”

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.

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.

All Silverado models feature a fully boxed frame that serves as the foundation for their strength and capability. The main rails and major cross members are formed from high-strength steel, providing a rigid base for maximum hauling capability.

“Elements such as high-strength steel in the frame and body structure are found on all production models, while some also feature aluminum suspension components, contributing to the Silverado’s everyday performance. With the Cheyenne concept, we’ve taken the low-mass concept to a new level – with exciting results,” Perry said.

“It is only a concept right now, but we are continually exploring new ways to give Silverado customers more.”

FAST FACT: Cheyenne was introduced as a premium Chevy truck trim level in 1971. The name also appeared a futuristic 2003 concept vehicle.
