In F1 one of the technologies uses is the KERS (Kinetic Energy Recovery Systems) also known as Hybrid Power System. The KERS are used within the automotive racing industry in order to reuse the kinetic energy under braking. This recovered energy is then stored in a flywheel or high voltage batteries. This is why when the system came into F1 the engineers were all spotted wearing protective gloves when attending to the cars. These systems are now also incorporated into public transport (such as the Cambridge Passenger/Commercial Vehicle Kinetic Energy recovery System.
KERS has tended to be at the higher end of the Motorsport industry, however now seems to be slowly moving towards making road going cars more green. GKN is to acquire the Williams Hybrid Power and re brand it as GKN Hybrid Power.
This change could offer up to 30% reductions in emissions simply by harvesting the energy that is lost through heat under braking. Another great example of how an often scrutinised sport is really the driving force and leader for what we may next see in our everyday cars (Perhaps not 120kW of addition power though)!
Williams F1 have also been utilising Autodesk Simulation CFD motion to great use on the aerodynamics of the vehicle. Check out the improvements to the software in the 2015 release.
