CNET GLOSSARY: Terms for the techie
Active steering electronically varies the degree to which the front wheels turn in relation to steering input from the driver and the speed of the vehicle. Under normal driving conditions at low and medium speeds, the steering ratio becomes more direct, meaning the wheels turn more in relation to input from the driver, reducing the amount the steering wheel must be turned. This enhances the car's performance in city traffic, when parking, or in curves. At high speeds, the steering ratio becomes less direct, meaning the wheels turn relatively less in relation to input from the driver and, thus, greatly reduces oversteering.
