A kinetic energy recovery system often known simply as KERS is an automotive system for recovering a moving vehicle ‘s kinetic mers under braking. The recovered energy is stored in a reservoir for example a flywheel or high voltage batteries for later use under acceleration. Xtrac and Flybrid are both licensees of Torotrak’s technologies, which employ a small and sophisticated ancillary gearbox incorporating a continuously variable transmission CVT.

However, the whole mechanism including the flywheel sits entirely in the vehicle’s hub looking like a drum brake.

Can flywheel technology drive out the battery from car hybrids?

The first of these systems to be revealed was the Flybrid. The system occupies a volume of 13 litres.

Two minor incidents were reported during testing of various KERS systems in With the introduction of KERS in the season, only four teams used it at some point in the season: Eventually, during the season, Renault and BMW stopped using the system. Their second KERS equipped car finished fifth. At the following race, Lewis Hamilton became the first driver to take pole position with a KERS car, his teammate, Heikki Kovalainen qualifying second. This was also the first instance of an all KERS front row.

He only took me because of KERS at the beginning”. WilliamsF1 developed their own flywheel-based KERS system but decided not to use it in their F1 cars due to packaging issues, and have instead developed their own electrical KERS system.


However, they set up Williams Hybrid Power to sell their developments. This was introduced to balance the sport’s move from 2. Bosch also offers a range of electric hybrid systems for commercial and light-duty applications. Several automakers have been testing KERS systems.

Peugeot planned to campaign the car in the Le Mans Series seasonalthough it was not allowed to score championship points. Vodafone McLaren Dlybrid began testing of their KERS in September at the Jerez test track in preparation flybrif the F1 season, although at that time it was not yet known if they would be operating an electrical or mechanical system. Both parties believed this collaboration would improve McLaren’s KERS system and help the system to transfer its technology to road cars.

Toyota has used a supercapacitor for regeneration on Supra HV-R hybrid race flybrod that won the Tokachi Hour endurance race in July This Supra became the first hybrid car in the history of motorsport to win such a race.

This system has many problems including the imbalance caused to the vehicle due to the flywheel.

Kinetic Energy Recovery Systems in Formula 1

Porsche is currently developing an electrical storage system. InMazda has announced i-ELOOP, a system which uses a variable-voltage alternator to convert kinetic energy to electric power during deceleration.

The energy, stored in a double-layer capacitoris used to supply power needed by vehicle electrical systems. The system is claimed to be much more affordable than competing electric and flywheel systems and kerrs expected on road cars by but was abandoned in KTM racing boss Harald Bartol revealed that the factory raced with a secret kinetic energy recovery system fitted to Tommy Koyama ‘s motorcycle flybri the season-ending cc Valencian Grand Prix.

KERS is also possible on a bicycle. This has also been demonstrated by mounting a flywheel on a bike frame and connecting it with a CVT to the back wheel.


In parallel, the packs were a regenerative brake; in series, they were a boost source.

A closer look at Torotrak’s Flybrid KERS

The vehicle remained in use so equipped until It was surplus disposed in Automobile Club de l’Ouestthe organizer behind the annual 24 Hours of Le Mans event and the Le Mans Serieshas promoted the use of kinetic energy recovery systems in the LMP1 class since the late s. The system consisted of high speed slipping clutches which transfer torque to and from flybfid vehicle, coupled to a 60, rpm flywheel.

The Audi R18 e-tron quattro uses a flywheel -based system, while the Toyota TS Hybrid uses a supercapacitor -based system. When Porsche announced its return to Le Mans init also unveiled an LMP1 car with fllybrid kinetic energy recovery system. The Porsche Hybridintroduced inuses a battery system, in contrast to the previous Porsche GT3 R Hybrid that used a flywheel system.
