Is Formula One racing out of step with an auto industry whose greatest innovations have been in the area of fuel economy? Maybe so, but not for long. The sport's governing body is pushing to introduce hybrid-drive systems in competitive racecars, beginning in the 2009 season. That's when F1 will require teams to install a kinetic energy recovery system (KERS), which uses a rapidly spinning flywheel to store a decelerating vehicle's kinetic energy, which would otherwise be wasted, and channel it back to the car's drive system. The sanctioning group, Fédération Internationale de l'Automobile (FIA), has defined the amount of energy recovery for the 2009 season as 400 kilojoules per lap, giving the driver an extra 80 horsepower over a period of 6.67 seconds. We asked Adrian Moore, Technical Director of Xtrac a few questions about the Formula One KERS system the company developed with partner firms Flybrid and Torotrak.
