Chevrolet introduced a performance-oriented Silverado concept truck on the eve of the 2014 SEMA showon November 4—think Camaro Z/28 with a bed and you've got the idea. Chevy pulled 200 lbs from the short-bed truck, added carbon ceramic brakes from the Z/28, a grippy suspension, and a 420-horse 6.2-liter V-8.
“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 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 look transforms the looks of the truck, from work machine to scream machine.
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.
“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 andrear park assist and a rear-vision camera, enhance safety without detracting from the truck’s performance.
“It is only a concept right now, but we are continually exploring new ways to give Silverado customers more,” Perry said.
This looks like a slam-dunk to us. We say bring the Cheyenne to production!
