To give a vehicle additional low speed agility, the wheels usually have a certain degree of toe 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. Because of this there’s always a compromise between low and high speed handling.
Prodrive claims its new system can match the handling of a vehicle with a complex multi-link rear suspension using just a traditional twist beam set-up. “Active Toe Control, fitted to an existing twist beam axle, can give many of the dynamic benefits of a multi-link system, but at less than half the cost,” Prodrive engineer Matt Taylor explains.
Officials are now looking for a hardware partner to take the project to a working prototype.
