The CFT KERS device may be connected to the vehicle transmission in any of the locations numbered 1 through 7 shown above. When using connection locations 1 through 4 there is the advantage of multiplying the number of gears in the CFT by the number of gears in the vehicle gearbox. In locations 5 through 7 the CFT KERS may be configured with more than three gears and the round trip losses for kinetic energy recovery are lower due to the proximity of the connection  to the vehicle wheels.
