Horsepower, torque, towing, and payload explained

What is horsepower?

Horsepower helps describe how quickly an engine can perform work. More horsepower supports stronger acceleration and confident performance at higher speeds.

What is torque?

Torque is the twisting force produced by the engine. Strong torque is especially useful when starting with a heavy load, climbing a grade, or pulling a trailer.

What is towing capacity?

Towing capacity is the maximum trailer weight a properly configured truck can pull. The engine matters, but cab style, bed length, drivetrain, axle ratio, and trailering equipment also affect the final rating.

What is payload capacity?

Payload includes the weight placed in or on the truck, including passengers, cargo, accessories and trailer tongue weight. The payload rating for a specific truck can be found on its vehicle certification label.

Seven models are planned:
