Engine Torqe Specs

While most people concentrate solely on the horsepower rating of a particular vehicle, the flip side to the horsepower coin is torque, which can drastically impact the way in which your car performs on the road. Understanding the torque specs of your engine and what they mean in real-world performance allows you to make a more informed buying decision.

Torque Definition

Torque is defined as the force applied to the crankshaft of the vehicle from the output of the engine. Torque is measured in pounds of pressure exerted per foot (lbs/ft), with the rating provided at peak torque performance along with the engine speed at which that level of force is generated. For example, 150 lbs/ft @ 3,000 RPM.

Torque Characteristics

The torque curve of a vehicle's engine is a graph showing the maximum amount of torque generated from zero RPM to the vehicle's redline. A flat torque curve indicates a vehicle that will have little trouble accelerating steadily from even low RPMs, such as the BMW 335i. A more peaked torque curve indicates a vehicle whose acceleration capacities are dependent on the driver keeping the car in the proper rev range, such as the Mitsubishi Evo FQ-400.

Torque Practically

When purchasing a vehicle, cars that generate peak torque at lower RPMs are generally more user friendly, as you will have to perform less shifting and changing gears in order to get the most from the engine. Cars with a more variable torque curve will require more finessing on a day-to-day basis to get the most from the engine, making them less practical for individuals simply looking to drive without hassle.
