If your adventures involve off-road excitement, GMC has unleashed a potent new Sierra. The AT4 starts with the 6.2L V8 and the 10-speed automatic co-developed with Ford. air intake and performance exhaust push the horsepower up to 435 with a whopping 469 lb-ft of torque.
Power of this magnitude allows the machined 18″ wheels and Goodyear DuraTrac tires to dig in. It arrives with a 2″ lift kit from the factory, thanks to Rancho suspension. Instead of polished stainless, the fog lights, grilles and fender trim is black chrome. The GMC Sierra AT4 also introduces the world’s first carbon fiber truck bed. It is stronger than steel and it can’t be dented by loose cargo. The MultiPro tailgate is also a wild upgrade.
