The 2020 GMC Sierra 1500 AT4 CarbonPro is a rugged full-size pickup designed for off-road performance and everyday utility. The AT4 trim brings a factory off-road suspension with a 2-inch lift, Rancho shocks, skid plates, hill descent control, and all-terrain tires, giving it strong capability on rough terrain.
What sets the CarbonPro Edition apart is its unique truck bed, constructed from a carbon-fiber composite material instead of steel. This makes it lighter, more resistant to dents, scratches, and corrosion, and it eliminates the need for a bed liner. The CarbonPro bed also provides slightly more cargo volume and added durability for heavy-duty use.
Under the hood, the AT4 can be equipped with powerful engine options including a 5.3L V8 or a 6.2L V8, paired with a 10-speed automatic transmission. Inside, the cabin balances rugged styling with premium touches, offering features like leather seating, advanced infotainment with Apple CarPlay/Android Auto, and available driver-assist technology. The MultiPro tailgate with optional integrated Kicker audio system adds versatility and convenience.
Overall, the 2020 Sierra 1500 AT4 CarbonPro is built for drivers who want a capable off-road truck with modern technology and the added toughness of an advanced carbon-fiber composite bed.
