Production cars likely to benefit from new F1 hybrid system

Posted Wed Jun 11 2008 12:33 PM by Kenneth Hall

The company behind the new kinetic energy recovery systems (KERS) currently being developed for F1 sees its new technology eventually being used in production cars and envisages a number of different applications for motorists. The hybrid flywheel system stores energy recovered when the car slows down in a rotating flywheel. This energy is then transferred back to the car’s gearbox when required, providing an extra boost of energy.

The system is being developed by UK company Xtrac and is set to debut in next year’s F1 season. Its creators believe that such a system could be used to boost energy from compact engines, act as a range extender in petrol-electric hybrid vehicles, or even power auxiliaries devices in regular production vehicles.

Despite being designed for the fast pace of F1 racing, the original concept was intended for regular production vehicles and could easily be adapted for volume manufacturing. The energy recovery rate and storage requirements of a flywheel for a road car could be considerably less than that required in F1 where the system has to handle energy recovered from up to 5g braking.

It’s still too early to say when the technology might be available in regular production cars but Xtrac is focused on the project and will present a paper outlining the key features of the system at the Global Powertrain Congress being held in the Netherlands this week.

Makes sense, looks simple.

and the key here is that most cars cant brake at 5g like F1.. more like 0.5G.

The problem is, how relevant will this technology be when the two biggest car makers are making lithium ion plug in hybrids in 2010?

This kind of system would be great for cars that simply are too big and MASSive to be considered as decent hybrid vehicles. I'm talking about you bentley and roller. hell, even MACK might be able to use something like this.

Something tells me that the energy expendature of an F1 car while racing is probably comparable to a fully laden Mack truck in city driving conditions.

any save is better then none.
not sure about the price

BS, this is a farce..a facade by F1 to appear green and a marketing move by xtrac to pimp its product. The ultracapacitor system in the Supra HV-R is way more efficient and advanced.
