An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.
Frank William Dernie (born 3 April 1950) is a British Formula One engineer. Dernie is credited with inventing active suspension, being the first engineer to use computer aided design, the first engineer to put a data logger on a formula one car and implemented the first on site wind tunnel (at Williams Grand Prix).
The Williams FW15C is a Formula One car designed by Adrian Newey and built by Williams Grand Prix Engineering for use in the 1993 Formula One World Championship.. As the car that won both the Drivers' and Constructors' Championships in the last season before the FIA banned electronic driver aids, the FW15C (along with its racing predecessor FW14B) was, in 2005, considered to be one of the most ...
After much testing Piquet found the car to be superior to the conventionally suspended FW11B. The new suspension was an active suspension system similar to the one Lotus had been using all season on the Lotus 99T, but was renamed as Williams Reactive Ride due to the Lotus team having copyright on the 'Active Suspension' name for the system. The ...
Ahead of the 1994 season, the FIA banned electronic driver aids such as active suspension and traction control. [12] [13] The speed of the change (the FIA was so eager to implement the ban that it initially suggested imposing the ban in the middle of the 1993 season [13]) was criticised by several drivers, who believed that it would lead to unsafe design flaws in the 1994 cars.
The McLaren MP4/8 was the Formula One car with which the McLaren team competed in the 1993 Formula One World Championship.The car was designed by Neil Oatley around advanced electronics technology including a semi-automatic transmission (which could be switched over to fully automatic), active suspension, two-way telemetry, and traction control systems, that were developed in conjunction with ...
The speed of Formula One cars had continuously risen over 8 years, despite turbocharged engines being made illegal, the width of tyres being reduced and driver aids eventually being removed. There was an "air of invincibility" in Formula One, a belief that the cars were inherently safe and no more drivers would die. [18]
In Formula One, the DRS opens an adjustable flap on the rear wing of the car, in order to reduce drag, thus giving a pursuing car an overtaking advantage over the car in front. The FIA estimate the speed increase to be between 10–12 km/h (6.2–7.5 mph) by the end of the activation zone, [ 8 ] while others, such as technical staff at racecar ...
