What is the torque of a car?

Question

The car is a clk the engine is a 6.2-litre and has a 481bhp(brake horse power) and a peak torque of 4641b

Answer 1

Torque is the amount of twisting power a car has. Think of it like changing a tire. If you have a stuck lug bolt and you get a long bar to break it free you have increased your torque.

Answer 2

Torque is a force that tends to rotate or turn things.
To calculate the torque, you just multiply the force by the distance from the center. In the case of the lug nuts, if the wrench is a foot long, and you put 200 pounds of force on it, you are generating 200 pound-feet of torque. If you use a 2-foot wrench, you only need to put 100 pounds of force on it to generate the same torque.

The point where the connecting rod attaches to the crank shaft is some distance from the center of the shaft. The horizontal distance changes as the crankshaft spins, so the torque also changes, since torque equals force multiplied by distance.
You might be wondering why only the horizontal distance is important in determining the torque in this engine. When the piston is at the top of its stroke, the connecting rod points straight down at the center of the crankshaft. No torque is generated in this position, because only the force that acts on the lever in a direction perpendicular to the lever generates a torque.

Answer 3

Are you asking what torque is? You seem to have listed the specs so I'm guessing you'd like them explained.

I'm thinking this is a put on, but here goes;

In simplest analogous terms, 6.2 litres is the amount of engine displacement which means the total size (quantity) of the chamber where the combustion occurs.

It can generate up to 481 HP (which relates to speed), and produces 464 ft lbs of torque (which is relative to power - speed and power are NOT the same thing).

Other than that, you might want to research it until it makes sense to you.

Answer 4

Torque is the twisting force the engine creates, and is measured in units of force x distance, either pounds-feet (lb ft), Newton-metres (Nm) or kilogramme-metres (kg m). The torque you attempted to quote is 464 lb ft.

Power is the work done by the engine in a period of time.
It has the dimensions of (force x distance) / time.
The common units are brake horse power (bhp), German horse power (PS) and kiloWatts (kW).

In S.I. units, the power of an engine at any given speed is the torque it produces at that speed multiplied by the rotational speed of the engine in radians per second. Therefore if torque is constant relative to engine speed, power will increase in proportion to the engine speed, so high-revs = high power.

In reality only turbocharged or otherwise supercharged engine ever produce maximum torque over a range of engine speeds.
Also each engine has a speed beyond which it can no longer burn its fuel/air mixture efficiently enough to produce maximum torque. Hence torque falls off at high revs. The rate of this fall-off determines how much higher the speed is at which the engine produces peak power.

In general a car-sized petrol engine will produce peak torque at around 4,000 rpm and peak power at around 6,500 rpm, while a diesel engine will produce peak power at just over 2,000 rpm and peak power at 4,000 rpm. Diesel engines tend to produce greater torque than petrol engines, but because they can't sustain this torque at high engine speeds they tend to produce less peak power.

Greater torque will lead to greater acceleration, or greater ability to tow, climb steep slopes, etc.
Greater power will lead to a higher top speed.

Changing the gearing of the car changes the torque applied at the wheels, but cannot change the power transmitted.

Answer 5

Peak torque is the MAXIMUM torque or twisting force the engine produces at a given engine RPM.

Answer 6

Think of it like this, torque is how hard you can punch and power is how fast you can punch. Therefore if you punch slowly you can get more force in, but if you punch fast you don't have as much force. Similar in a cars engine you have a lot of torque at low engine speeds and a lot of power at high engine speeds.

Answer 7

Torque is an odd measurement of turning/rotational power - power is just brute force, torque is how that force gets applied to the driving wheels, and ultimately, the road, to produce forward (or backward) motion.

Diesels typically produce significantly more torque than petrol engines, but bizarrley, produce less raw power.

Answer 8

In a nutshell it's the speed of the accelleration, So when you accererate the response you get is known as torque. Geeks often talk about low-end torque and high-end torque. This refers to what rpm you engine is running at.

Answer 9

foot pounds, inch pounds or newton meters all are units of measure used to determine how much torque is applied the nuber at the end of your question sounds as if it must not be refering to torque because 481 bhp cannot make 4641 foot pounds of torque go to your library or use your search abilties online and find your answer to just how much torque can be produced by x amount of hp it is a formula.

Answer 10

Torque is the twisting or turning force againt a load.
