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.

Lightweight features built into the concept vehicle include carbon fiber replacements for the bumpers, tailgate and inner cargo box, resulting in a weight reduction of approximately 200 pounds (91 kg) from the 4,503 pounds (2,043 kg) base curb weight of a 5.3L-equipped Silverado regular cab with a 6’6” box.

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 (9 kg)—and save un-sprung weight, too, which enhances driving performance with more immediate and direct handling.

The Cheyenne 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.

T

he all-new EcoTec3 6.2L V-8 that powers the concept truck is rated at 420 hp and 460 lb-ft (624 N·m) of torque. 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.

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

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.
