Jaguar Experimenting With Hybrid XF Sedan

Jaguar debuted an XF sedan that utilizes a new type of hybrid system, one that recaptures energy through a mechanical flywheel rather than a battery system.

Dubbed Flywheel Hybrid System for Premium Vehicles(FHSPV), the new technology is being developed with engineering powerhouses like Ricardo, Prodrive and Xtrac, who all have significant experience developing parts for race cars. “The FHSPV is really an engineering due diligence exercise,” says the project’s engineer Daniel Loftus. “We need to look at mechanical flywheels and see how they compare with electric hybrids. And then see if they have a production future.”

The flywheel puts power to the ground via an Xtrac-developed CVT gearbox, and can produce an extra 80 horsepower for a seven second time period. Combined with a start-stop system and a package size that weighs half of a traditional hybrid system, the FHSPV can also deliver a 20 percent fuel economy savings.

The one obstacle stopping the FHSPV from production is the falling cost of battery systems. Hopefully, the technology sees the light of day, as it seems to offer a lot of promise.
