After months of teasing, the 2023 Ford Super Duty was finally unveiled last week, debuting with revised exterior and interior styling along with the all-new 6.8L V8 engine, as Ford Authority exclusively reported. Recently, Ford’s crosstown rival, General Motors, debuted a refreshed 2024 Chevrolet Silverado HD that will go head-to-head with the new Super Duty.

The off-road-oriented AT4X trim level will arrive later on in the 2024 model year, adding equipment such as tough underbody protection, revised bumpers with greater ground clearance, revised suspension, and Goodyear Territory MT tires and more. The pickup is available in 2500HD and 3500HD models, offered in Regular Cab, Extended Cab and Crew Cab configurations. Dual-rear-wheels are available on 3500HD models, which also offers the pickup’s most robust trailering capacity of 36,000 pounds.
The 2024 GMC Sierra HD sports a new front fascia and exterior styling, as well as a completely overhauled interior with a 13.4-inch infotainment screen, a 12.3-inch configurable driver information center and a redesigned wireless phone charger.
