DETROIT — Defining the premium off-road segment, the 2019 GMC
Sierra AT4 is now available with the all-new Off-Road Performance
Package. The Off-Road Performance Package adds factory-installed
performance upgrades that bring additional power and purpose to the
Sierra AT4.
“The 2019 GMC Sierra AT4 debuted all-new, purposeful technologies for
the premium truck segment and the new Off-Road Performance Package
takes it a step farther,” said Duncan Aldred, vice president of Global
GMC. “It offers optimized performance, both on- and off-road.”
The Sierra AT4 Off-Road Performance Package includes:
- 6.2L V-8 engine mated to 10-speed automatic transmission.
- 18-inch machined aluminum wheels with Goodyear Wrangler DuraTrac tires.
- Cat-Back Performance Exhaust System.
- Performance Air Intake.
Thanks to these additions, the AT4 Off-Road Performance Package
delivers up to 435 horsepower and 469 lb-ft of torque — increases of 15
horsepower and 9 lb-ft of torque over a Sierra equipped with a
conventional 6.2L V-8 engine. The 6.2L is manufactured at GM’s Tonawanda
engine plant in New York and was recently named a Wards 10 Best Engine
for 2019.

significantly improved engine or electric propulsion system available in

The Off-Road Performance Package’s upgrades build on the Sierra AT4’s

technology and bold design, along with GMC’s premium refinement.
