GMC Sierra AT4 Pickup Receives Important ChangesDecember 18, 2018
Under the hood, off-road version of the American pickup is a modernized 6.2-liter V8 engine, whose power increased by 15 hp. I must say that GMC Sierra is the nominee for the Truck of the Year Award.
Engineers from the American brand GMC decided to slightly upgrade their full-size GMC Sierra AT4 pickup. It is reported that due to the exhaust system with feedback and improved air intake, the power plant can boast a power of 435 horsepower (636 Nm of torque).
Compared with the usual version of this V-shaped power unit, the power gain is 15 hp and the torque has grown by 12 Nm.
Together with this engine, a 10-step “automatic” works, which transmits torque to all four wheels at once. The new version of the GMC Sierra AT4 with the Off-Road Performance Package is worth $ 4,940. In this performance, the car received a set of 18-inch wheels with black parts. Well, the off-road tires Goodyear Wrangler DuraTrac provide enough “hook” on the roads.
The American truck also has a factory-mounted suspension lift of 50.8 mm, as well as high-performance shock absorbers. To work with rough terrain, there is a full drive with a 2-speed transfer case and locking rear differential. Hill descent control system and Traction Select system offer additional assistance in such races.
