2015 Chevrolet Silverado HD and GMC Sierra HD

A Fresh Look for 2015

Heavy-duty pickup trucks, defined by a gross vehicle weight (GVW) of 8,500 pounds or higher, account for a quarter of full-size pickup sales in the U.S. Interestingly, about two-thirds of heavy-duty pickups are diesel powered. Because these workhorses are valued for their towing capability and durability, the 2015 Chevy Silverado and GMC Sierra are created to be stronger and smarter.

Recall that 2011 marked inner improvements for the HD Silverado and Sierra with new chassis and fully boxed frames, and an updated Duramax engine and Allison transmission. For 2015, exterior changes and other improvements resembling those that the 1500 line received for 2014 will be implemented. Look for unique chrome bumpers, HD hoods and headlamps, and prominent cooling intakes to differentiate the HDs and also the GMC and Chevy brands. The front is designed for enhanced cooling by enabling the engine air intake to be isolated from the hot engine compartment, keeping intake air cooler. The design also improves aerodynamics for a quieter cabin and overall efficiency. Moving toward the rear, the new CornerStep rear bumper allows for easier cargo access, along with hand assists molded into the bedrail protectors. The downward slam of the tailgate is controlled by an EZ Lift damping system.

The new interiors might look familiar if you’ve been inside a new 2014 Sierra or Silverado 1500. Quiet and insolated (due to inlaid doors and triple door seals), these interiors feature increased space and comfort and extensive storage. The cab is all-new as well, made of high-strength steel and set upon hydraulic body mounts.

Towing and hauling improvements include fully integrated cruise control, auto grade braking, diesel exhaust brake, integrated trailer brake control, hill start assist, hill descent control, and StabiliTrak with trailer sway control. To plan for the unplanned, a driver alert package includes Forward Collision Alert, Lane Departure Warning, available Safety Alert Seat, rear camera, front and rear park assist, and side curtain and seat-mounted side airbags. Also expect best-in-class payload (7,374 pounds), and towing capacities of 19,700 pounds with a factory hitch and 23,200 pounds with fifth-wheel towing.

As for what’s under the hood – well, don’t expect any changes for now, unless you’re looking for a bi-fuel version of the Silverado HD or Sierra HD, which will be available for the 2015 model. The fully-warranted bi-fuel version has a 6.0L V-8 engine with special hardened valves and valve seats that enable it to alternate between gasoline and compressed natural gas (CNG) with the push of a button.

Be on the lookout for these giants to hit dealer floors during the first quarter of 2014.

That ugly son of a bitch should have a Toyota emblem on the front. First it was being ugly ass new Camaro and now the latest version of the ugly ass Silverado. I believe that Government Motors idea of moving their styling department to China was the wrong thing to do and has definitely given most of their vehicles a strong Asian look

And just so you know cupped front tires are caused by two things... under inflation of the tires or worn ball joints. Both of which cannot be avoided regardless of what style front end you have.

Unlike yourself Ben I am an adult. I purchased my own truck with my own hard earned money and must fix it when it breaks with my own hard earned money. I do not drive a Cummins just to look cool and pick up chicks. I drive it because the Cummins is by far the longest lasting and most reliable diesel available and dodge is the only manufacturer who have not permanently stuck their heads in there ass and done away with the manual transmission option as Ford and Chevy have. So go ahead and continue to run your mouth about me only driving a Cummins to be cool

The overly complicated injection system on the 7.3 really hinders its performance possibilities.

Abe Cyr

Brandon Laws has obviously never been to the biggest diesel event in the country (Scheid Diesel Extravaganza)or any major diesel truck pull. I will agree that the 7.3 is the best option besides the Cummins but they are by far not the most popular and sought-after diesel engine in the country as you say they are. Compared to the Cummins the aftermarket for 7.3 performance is almost non-existent and ability to gain big horsepower numbers is just not as easy or anywhere near as cheap. The Cummins is the small block GM of the diesel world and by far the most popular diesel engine in the country.

Abe Cyr

Just as ugly as the half ton and those wheels look like they belong on a sports car, not a heavy duty pickup truck. Not to mention ,it still has IFS and that shit is junk!!! Dodge and Ford still use a solid front axle for a damn good reason

Gil Gin

don't matter, both the 7.3 and the cummins are better than this chevy junk

Nick J Pears

7.3.... what truck comes with that now. 12valve.... what truck comes with that now Both good motors but not a dealer option in a 2014 anything.

Bryan Shaw

7.3 the most sought out in North America , LMFAO that's some funny shit right there.

For those of you laughing at the tow rating my question is this how many times have you towed over 20k. Its not practical for every make to compete in this man grunting I can tow more contest. Chevy has the cowboy Cadillac. Its a capable truck that doesn't compromise ride for payload. I rate 6/10 for its appearance

Brandon Laws
Brandon Laws

Anyone can run their mouth online. Just admit it. Your a Cummins fan. The 7.3 is still the most sought after diesel in North America. More than Duramax and Cummins Combined. Its a reliable bullet proof engine. Now, am I talkin Duramax and Cummins down? Absolutely not. Each 3 brands have theyre highs and lows. But if you got 3 7.3L's that you supposedly say is "junk", it makes me wonder what your doing wrong. I know several people with em, stock and built, and not one problem.
