Horsepower, Torque and Transmission Explained
Horsepower
Helps describe how quickly an engine can perform work. More horsepower can support acceleration and higher-speed demands, but vehicle weight and gearing shape the result.
Torque
Measures rotational force. Where peak torque arrives in the engine’s speed range affects how responsive the vehicle feels during everyday acceleration.
Transmission
A CVT changes ratios continuously, while 6-, 8- and 9-speed automatics shift through fixed ratios. Drive each type in the conditions that matter to you.
