What causes torque steer on a car?
Torque steer is a sensation that is commonly experienced in powerful front-wheel-drive cars. It happens under acceleration as the torque delivered by the engine overcomes the front tyres, resulting in either the steering wheel ‘tugging’ in your hands, or the car pulling to one side of the road as you accelerate.
Do front-wheel drive cars have torque converters?
The main elements of the power train of a front-wheel-drive automobile are the transversely mounted engine and the transmission, which transfers the torque, or turning energy, of the engine to the drive wheels through a short drive shaft.
Where does the torque in a car come from?
When we drive at highway speed, the engine is supplies constant power to the drive wheels. Though we may not consider this acceleration, the effect is on our vehicle is similar. If the engine transmits more torque to one side, the vehicle will roll in that direction.
How does a torque steer work on a car?
This is when the steering wheel turns to one side, when taking off. Releasing the throttle makes the problem far less noticeable. The vehicle may also drive straight once speed is obtained. A torque steer can also produce a steady pull in the steering, while the throttle is applied.
What causes a car to pull toward the side?
With other factors equal, a vehicle will pull toward the side with the lower angle. Bad engine mounts, bent frame or body components are often a cause for this type of misalignment. Changes to axle angle, in either plane, will affect the torque transmitted. The more of an angle, the less torque is transmitted.
Why does my car pull out of gear?
Applying constant pressure to the steering wheel to maintain straight tracking may feel like a wheel alignment or tire issue. To diagnose the problem, the vehicle is driven at the speed, at which the pull occurs. The throttle is released, and the vehicle is shifted out of gear.

What does it mean when a car torque steers?
Take both hands off of the steering wheel and give the accelerator a brief but firm squeeze. What did you notice? For most FWD cars, you likely saw the steering wheel twisting to one side and the vehicle lurching to either the left or to the right. Some cars pull more than others, but what you just witnessed is torque steer.
How can I control the torque in my car?
Another solution is to use some sort of differential technology to control what wheel gets the torque.
