The fast-moving world of motor racing technology

03 June 2019

The fast-moving world of motor racing technology is constantly changing because of the desire to gain an advantage in such a highly competitive arena, as well as the need to comply with ever-changing rules and regulations. This is especially true since the introduction of an all-electric racing series – the ABB FIA Formula E Championship.

Back in 2011, a decision was made to allow the use of driver-activated rear wings in Formula 1, a return to the motor sport 40 years after they were banned on safety grounds in the 1960’s. 

This meant drivers could control the rear wing once they have been behind another driver for a set amount of time, thereby reducing drag on the straight and allowing greater opportunity for overtaking. The wings are raised and lowered by a large diameter hydraulic actuator which needs to move very quickly and therefore demands a fast-acting, high flow valve to control it. In fact, Lee Products specifically developed its 250 series solenoid valve and a version of its 3-way, high flow solenoid valve for DRS at the request of its F1 customers and these were subsequently homologated by the FIA for use in F1.
