September 27, 2013 – The 2015 Silverado HDs are designed to bring new levels of confidence to tough towing, says Chevrolet, through further refinement of Silverado’s available Cruise Control, Auto Grade Braking and Diesel Exhaust Brake; the integration of these features helps the 2015 Silverado HD maintain a set speed up and down grades.

On Duramax diesel models, the driver can engage the Diesel Exhaust Brake, which uses the variable vanes in the turbocharger to smoothly and quietly create additional backpressure in the engine to help slow the vehicle. StabiliTrak with Trailer Sway Control is now standard on all Silverado HDs, including 3500 dually models.

Payload and towing capabilities of the 2015 Silverado HD are increased from 2014 models: maximum available payload is 7374 lb; maximum available conventional towing is 19,600 lb with the available factory hitch; and maximum available fifth-wheel towing is 23,200 lb.

Silverado HD is available in more than 150 combinations of cabs, bed lengths, powertrains, drivetrains and axle ratios, enabling customers to spec exactly the right truck for their towing and hauling needs.

The 2015 Silverado HD receives the same updates to the interior, cab structure and door designs as the Silverado 1500. The upright instrument panel, six-gauge instrument cluster and multiple storage options are tailored specifically to the needs of truck customers. Controls are functional, logically placed and easy to operate while wearing work gloves, says Chevrolet.

The rear doors on crew-cab models are larger and, combined with revised seats, create about 2-in. more rear legroom, and enable easier entry and exit for back seat passengers. A new double-cab model, which features forward-hinged rear doors, replaces the previous extended cab, and allows easier access to the back seat—especially in tight parking spaces.

The 2015 Silverado HD offers three powertrains. The Duramax 6.6L turbodiesel and Allison 1000 6-speed automatic transmission combination will continue to be available on both 2500 and 3500 Silverados. The standard engine on all Silverado HDs is a 6.0L Vortec gas V-8 with continuously variable valve timing, matched with a six-speed automatic transmission. It is rated at 360 hp and 380 lb-ft of torque on 2500 models, and is engineered for low-end torque. A version rated at 322 hp is standard on 3500s. Pickups with either version are E85 FlexFuel capable.

A bi-fuel version of the 6.0L V-8, with hardened valves and valve seats to enable operation on gasoline or compressed natural gas, will be available in all three models of the new Silverado HD.
