What does torque refer to when talking about cars?

Posted at: 2015-01-07 
pistons moving up and down spin a crankshaft. this spinning motion is the engine's torque which allows it to spin a gearbox and move the rest of the car.

Basically, the more torque the engine in a car makes, the easier it is for that car to accelerate. For instance, a car with a 200-horsepower engine that also produces 175 lb.-ft. of torque might be able to accelerate to 60 mph in 7.4 seconds. If the torque of that same car's engine were increased to 205 lb.ft. of torque, then, it might be able to reach 60 mph faster, maybe in 7 seconds flat or less, along with a slight increase in top speed. Similarly, a car with an engine that produces 200 horsepower and 600 lb.ft. of torque would accelerate faster than the car with the same amount horsepower but only 205 lb.ft. of torque.

Heavy load trucks depend on high torque. Those trucks usually are powered by diesel engines that produce very large amounts of torque. Without such high torque output, those trucks would struggle to get moving.

Torque is usually measured in lbs/ft. It is the rotational force of the engine. Engines usually develop peak horsepower at a high engine speed, so low speed torque is what makes your car take off quick. You normally drive with engines in the peak torque range, not the peak horsepower range. Hope this helps.

Torque is essentially a measure of the car's engine ability to produce power at low RPMs, which is essential for low speed performance and pulling power. Torque is converted to power and speed by the car's transmission -- power in low gears and speed in high gears.

tourque is what make the car move or accelerate

i always hear or see on tv or on news articles

this car is amazing with such and such foot pounds of torque

excuse my ignorance but i know nothing about cars

from school i know torque is the product of force times the arm to the point of rotation

basicly like a bar rotating about a point

and has units of Nm or joules

but then you have the other one WORK which is also Nm or joules

so what are they referring to in cars?
