GM has just unveiled the all-new Serra AT4 pickup.
The New York Auto Show will kick off this weekend, and GM is getting ahead of the game by unveiling their all-new GMC Sierra AT4.
And AT4 is more than just a new trim level for the already highly trimmed Sierra. It’s going to be GM’s new all-terrain sub-brand. Whether or not it’ll go beyond GMC has yet to be seen, but here’s hoping they come out with an AT4 version of the Corvette to tell us one way or the other.
But back to the Sierra. The sort-of new truck comes with new versions of the 6.2L and 5.3L V8 engines that Sierra owners have come to know and love, along with the all-new Duramax 3.0L inline-six turbo-diesel engine for diesel lovers. Power figures on these new engines haven’t been released, but the regular 5.3L gets 355 hp while the 6.2L gets 420 hp. We’ve never seen the turbodiesel, so your guess is as good as ours.
The 6.2L and turbodiesel engines are mated to a 10-speed automatic, while the 5.3L gets the usual 8-speeder. The 5.3L and 6.2L engines also come with Dynamic Fuel Management, which is a fancy way to say that the engine turns off cylinders when they’re not needed to save gas.
The standard version of the AT4 will come with the 5.3L engine, while the other two are optional extras.
All versions of the AT4 get a 2-inch lift kit over the original Sierra, a set of Rancho monotube shock absorbers, 4WD with a 2-speed transfer case, locking rear differential, and selectable traction control that lets you choose between a number of terrain types.
If the wheels in the image look a little small, that’s because they’re 18-inch all-terrain tires that have optional mud-rated tires for those expecting to get wet. There’s also a set of 20-inch wheels with all-terrain tires if you feel a little insecure about the 18-inchers.
Safety features include blind spot monitoring, lane keeping, front pedestrian braking, and low-speed collision braking. An optional full-color heads-up display is available, as well as a carbon fiber bed if you demand lightness from your light, all-terrain trucks.
Coolest of all, the AT4 Sierra comes with GM’s fancy new MultiPro adjustable tailgate that turns into 6 different things depending on how you open it.
Pricing hasn’t been announced, although you can expect it to cost more than the higher trim levels of the Sierra, and it goes on sale in the fall.
