When Ford first revealed the new 2012 Focus at the North American International Auto Show almost a year ago it was vague about a new 'torque vectoring system' that's designed to improve handling.
The Blue Oval has now released a description of the system and how exactly it will benefit customers. Essentially it's a form of electronic limited slip differential that works by adding brakes to the inside wheel in a turn to slow that wheel and ensure both wheels turn at the same rate. The result is a car that handles better (good for driving enthusiasts) and is also more stable (which is a benefit to all types of drivers). The small application of the brakes is imperceptible to the driver.
Ford's decision to offer the technology on all Focus models is impressive as previously these setups were only available on some sports cars or high-trim versions of cars, like in JCW MINIs and the VW GTI.
