What Is "torque"

[KwlAznKid]

people keep talkin bout if "torque" is good or bad i don't really understand the difference what is the big.. difference between cars with different amounts of torque? sorry if this is a noob question i don't know much about cars =( help me out guys? thanks

The higher your torque, the faster your acceleration. Torque is the force needed to move a specific weight. In car, the higher the torque the better...and I say better because your car is faster

[I_like_bimmers]

Any force that acts to produce rotation. The measured ability of a rotating part, such as a gear or shaft. F - couple S - par

The static twisting force produced by an engine. Torque varies with the length of the "arm" at which the twisting force is measured. Torque is a force times the length of the measurement arm: Torque = Force x Torque Arm, where Force is the applied or the generated force and Torque Arm is the length through which that force is applied. Typical torque values are ounce-inches, pound-feet, etc. :wink

The measure of the force applied to produce rotational motion usually measured in foot-pounds. Torque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied.

i see thanks! but have you seen the movie taxi? there's htis one part the 760 li and the ford car is racing and queen latifa pulls up nex to the 760 and she goes like "too much torque" how is that bad?...

For example, E30 M20 has 168 lbs-ft, that means that the camshaft rotates which pulls 168pounds per one foot, basically faster accel, just like M3Rider said. Your pushing 168pounds per 1 foot, accelerating. Also, the more torque you have, the more weight car can transport with higher speed, like big ass trucks and shit

oh isn't there something like if there's a lot of torque u can't go fast though? like some suv's hav 333 hp but so does m3 but m3 could defintely burn the suv so does this mean the m3 has more torque than the suv?

thanks btw

You don't need as much torque to pull a vehicle that weighs much less.

The only phrase of "too much torque" i've ever heard is in reference to the new Benz CL65 AMG because it can potentially have up to 900 lb foot torque but that would probably bend the chasis cuz it's just so uber leetsauce OMFG WTF mate insane

The best description I ever heard about the difference between torque and HP is

Imagine a speedboat with a 40HP motor. It can go 30mph and pull one waterskier. It has a fixed amount of horsepower and torque produced by the one motor.

If you add a second motor alongside the first motor, you now have 2 x 40 HP motors. You can still only go 30 mph - but now you can pull 2 waterskiers. you have doubled the torque produced by the boat.

If you now swapped the 2 x 40HP motors for one 80HP motor with the same torque as one of the 40hp motors, you might be able to go faster than the 30mph but you cannot pull the 2 skiers. - you have not increased your torque

The Torque is the pulling power produced by the motors whereas the HP translates to the raw speed, this way a 4x4 can have a lot of torque (i.e can pull a big trailer) but not much speed.

Another way too look at cars and torque relates to gearing....

A friend had an MG ZS. 2.5L V6 engine producing only 180 BHP but with 240Nm of torque.

My old Accord Type R had a 2.2L with 212 BHP but with only 215Nm of torque. It was also a slightly lighter car.

I should have been faster looking at BHP but what happend was he beat me 0-120Mph every time....

The reason was that his gearing was able to take account of the available torque and pull a higher load across the whole range of a gear. So even though we would see-saw back and forth, eventually he would pull out a car length of lead. It really came down to his power being more available throughout a gear where mine was in a smaller range.

The real thing is to way up the BHP, the torque, the weight of car and the gearing....I think it's easier to just look at a manufacturers 0-60mph figure and use that to compare.

Wow. I can see how a n00b might get cornfused trying to figure this out.


Simplest way to understand torque.

Ever use a door knob?

How hard you twisted it = torque
How fast you twisted it = horsepower

Torque is what you feel when you launch from a stop. F = Ma.
HP is what gets you past that big rig on a twisty two lane road. HP = T(rpm).

A 90 hp 150 Lbf-ft diesel Jetta will lay a strip of rubber at a red light, but can't get out of its own way much above 70. Compared say to a 318...

Excellent description.

KwlAznKid,

Remember that torque doesn't have a time value associated with it - a 2000 ft-lb motor could turn at 1RPM. Not useful for good acceleration

HP and torque must be taken together - no single figure will tell you a complete story about the approximate acceleration or speed profile of a car.

[komodo]

But if you have too much torque on a light car (for example), you are prone to sitting there and spinning your tires for a second before you go anywhere... adding seconds to your launch.

I believe that's why in the movie Taxi, she says "too much torque".

[KwlAznKid]

ah i have a much better understanding now thanks for the help from all you guys! =D
