Prodrive develops Active Toe Control
March 14, 2008 by George Skentzos
Prodrive is a relative unknown outside the world of motorsport, however it has had a strong influence behind the scenes, developing technologies used by some of the world’s best handling cars.
Closer to home, Prodrive manufacture up to 3,000 vehicles a year in Australia through a joint venture with Ford Performance Vehicles.
Still confused? Then allow Top Gear to give you a brief history.
It’s latest breakthrough is a new vehicle dynamics technology dubbed Active Toe Control, which actively adjusts the wheel’s angle relative to the longitudinal axis of the vehicle – that is, the toe angle.
Working on the rear axle, by adjusting the toe angle depending on the speed of the vehicle, it improves handling at lower speed and is much more stable and predictable at high speed.
To give a vehicle additional low speed agility, the wheels usually have up to a degree of toe-out at the rear axle, while to make a car more stable at higher speeds, for emergency manoeuvres like a lane change, then toe-in is preferred.
This behaviour is currently achieved through the use of expensive multi-link rear suspension. The benefit of the Active Toe Control system is that it can be fitted to the existing twist beam axle, which can give many of the dynamic benefits of a multi-link system, but at less than half the cost.

Improved straight line stability without scrubbing your tyres, Excellent
Stick It on FPV’s,that and virtual pivot on the front would handle awesome especially on the 6’s
can someone tell me how 4 wheel steer works?
this sounds similar to me, and remember they had 4WS on the old TX5’s
I think those old rear steer set ups may have had up to three degrees on its steering angle
maybe more
honda preludes also had 4WS. Tighter turn in was normally the outcome. Forklifts can give you an idea of how it would effect a car
