Electric Rack & Pinions

Engineers in the last decade decided to replace the old-school hydraulics with electric motors, which isn’t surprising considering the general shift towards entirely electrically-powered cars. The motors are usually placed either at the base of the steering column or directly on the steering rack and have become a fairly simple solution to advancing power steering into the 21st Century. Electronic sensors pick up the amount of steering lock being applied and add in a proportional amount of additional force to the steering input. Electrical charge is used to rotate the motor and through energy transfer, a lateral force is produced that aids the movement along the steering rack.
