Powertrain

Back in February, GM Authority was the first to report that the 6.6L V8 L8T engine was imminent for the Chevrolet Low Cab Forward truck. First introduced in the all-new 2020 Chevrolet Silverado 2500 HD and 3500 HD pickups trucks, the new L8T engine was later announced for the 2021 Chevrolet Low Cab Forward truck in March, offering up more power and torque than the 6.0L V8 L96 engine which it replaces.

Engine Fuel Transmission Horsepower (HP) / Kilowatts (kW) @ RPM Torque (lb-ft) / Newton-Meters (N-m) @ RPM Axle

The trucks are built by Isuzu for General Motors.
