2019 GMC Sierra AT4: New York Auto Show

At Pier 36 in New York City on the banks of the East River, the all-new 2019 GMC Sierra was on display after debuting in Detroit earlier this month. But this time, it was accompanied by a different version of the Sierra that we haven’t seen before: the 2019 Sierra AT4, an all-new off-road variant of GMC’s flagship pickup.

The 2019 GMC Sierra AT4 is the first installment in a new sub-brand for GMC. This is the first AT4 vehicle, but it won’t be the last. Currently, off-road variants of GMCs are marked with “All Terrain” trim levels, but that’s about to change. In the same way the Denali sub-brand has moved GMC trucks and SUVs further upmarket, the AT4 division will move the brand further into off-road territory.

The GMC Sierra AT4 is a unique take on off-road capability in a premium package. Usually, off-road variants of pickup trucks are great at what they’re made to do but aren’t all that luxurious. The Sierra AT4 gives you the best of both worlds. It isn’t quite as opulent as the Denali, but it’s still a very nice truck with a lot of off-road capability.

Upgrades to the GMC Sierra AT4 include a 2-inch lift, standard 4-wheel drive with a locking rear differential, skid plates, off-road Rancho shocks, hill descent control, a traction select system and red vertical recovery hooks.

Like the GMC Sierra we’ve already seen in SLT and Denali form, the AT4 model comes standard with the industry-exclusive MultiPro tailgate. It can be folded into six different positions, making it extremely flexible. Loading and unloading cargo has never been easier.

The standard engine in the Sierra AT4 is a 5.3-liter V8. If you want to upgrade, you can also get a 6.2-liter V8 or a 3.0-liter turbodiesel inline 6-cylinder. The 6.2-liter V8 and the 3.0-liter diesel come with a 10-speed automatic transmission to maximize both performance and fuel economy.

Other available features on the AT4 include a rear camera mirror, a multicolor head-up display, a carbon-fiber bed and a suite of safety features like a surround-vision camera, lane-change alert with side blind spot monitoring, front pedestrian braking and low-speed forward automatic braking.

If you’re in the market for a premium, full-size pickup truck that’s as at home off-road as it is on the highway, the 2019 GMC Sierra AT4 should be at the top of your list.
