2023 Chevrolet Silverado 2500 HD | Heavy-Duty Truck

The 2023 Chevy Silverado’ 2500 sports a regular gas-powered 6.6-liter V-8, which has 401 horsepower & 464-pound-feet of torque & mates to a six-speed automatic transmission. The Duramax has a diesel 6.6-liter V-8 from the former generation with 445 horsepower and 910 pound-feet with the ability to connect to an Allison 10-speed automatic. All of the engines can hook up with rear- or four-wheel drive with compatibility for the single- or dual-rear-wheel axle. Such gas engine and six-speed automatic work well together for controlling truck speed. However, the Duramax powertrain is most reliable for towing heaviest loads. These options prove the Silverado is the way to go.
