- New eight-speed transmission for 6.2-L V-8 models
- Available Wi-Fi hot spot capability
- Close relative of the Chevrolet Silverado 1500
Offering full-size capability and refinement, the 2015 GMC Sierra 1500 pickup truck is ready to tackle (or tow) whatever you can throw its way.
Though it received many changes in last year’s refresh (including new styling and new engine options), the 2015 version of the Sierra 1500 does not rest on its laurels. Models with the EcoTec 6.2-liter V-8 equipped now feature a new eight-speed automatic transmission. GM’s OnStar communications suite also adds new technology that turns the Sierra 1500 into a Wi-Fi hot spot via a 4G LTE connection that allows you to use devices on the go.
Last year’s changes included a revamp of the Sierra 1500’s exterior styling. It is now a boxier look, with a large rectangular grille up front and squared off fender flares down the sides. The hood has two prominent bulges that give it added definition. Large headlight clusters flank the grille, with optional LED daytime running lights that line the top and bottom. The Sierra 1500 comes in three cab sizes (regular, extended, and crew) and in short/standard bed lengths out back.
Under the hood, the 2015 Sierra 1500 utilizes the latest in GM engine technology. The three engines (all designated under the name EcoTec3) feature technology like cylinder deactivation, continuously variable valve timing, and direct injection to operate more efficiently while still delivering plenty of power and torque. A 285-hp, 4.3-liter V-6 is the base engine, while those looking for more power can step up to one of two V-8 options: a 355-hp, 5.3-liter V-8 or a 420-hp, 6.2-liter V-8. Rear-wheel drive is standard, with four-wheel drive optional. The V-6 and the smaller V-8 are mated to a six-speed automatic transmission, while the larger V-8 gets the aforementioned eight-speed automatic.
The Sierra 1500 also got a new interior last year, with large gauges that can be operated even with gloved hands. There are also more standard features than you’d find in most trucks, with a USB port, power windows/locks, air conditioning, and a 4.2-inch display for the audio system coming on every model. A larger 8-inch screen, Bluetooth connectivity, dual-zone automatic climate control, and heated front seats are also available.
There is also plenty of available safety technology including forward collision warning, lane departure warning, rearview camera, hill descent control, and front/rear parking sensors.
