Geneva Motor Show Porsche 911 GT3R Hybrid Racer and kinetic drive


Not content to launch a new Cayenne in hybrid form and a stonking 918 hybrid concept at Geneva, Porsche showed a hybrid version of its new GT3R racing car. Set to race for real at the Nürburgring, this is no concept but a fully fledged 911 endurance racer. What sets it apart from the competition, particularly in the hybrid sense, is that it runs a flywheel type energy recovery, storage and power plant to supplement the 4 litre flat-six petrol engine engine in the tail rather than a battery pack.

Electrically spun, the flywheel stores kinetic energy and transfers it back to twin front electric drive motors, effectively giving 4 wheel drive on demand. Braking electrically respins the flywheel for a 6-8 second burst of extra power and traction. No word from Porsche as to whether there are any negative gyroscopic effects in the corners (or at all), but it should be more stable at high speed if the flywheel mass is sufficient. The system appears to rely on its high rotation speed rather than pure spinning weight. And anyway most cars have four spinning gyroscopes covered in rubber; one at each corner ;-)
So how would you feel about sitting next to what looks like a personal nuclear fusion reactor ? Should be fine really as it’s just a disc spinning at, err, 40,000rpm….but at least it has been developed by Williams Hybrid Power Ltd and Torotrak so does have some F1 technology built in.

Porsche GT3 R launched at Autosport Racing Car Show

Porsche just launched their new GT3 R racer. This a special race edition of the already hard core road going/trackday car, designed to appeal to (rich) amateur racers, yet fully meeting FIA GT3 regulations. Porsche’s stand at the Autosport Racing Car show was buzzing with interest, and we are told that the GT3 R’s have nearly all been bagged already. It’s yours for a cool 279,000 euros in basic trim…

Porsche GT3 R

It looks a racer if every respect, harking back to earlier Le Mans entries with it’s bolt on rear arches, massive rear wing, single vertical wiper, quick-fill fuel nozzle. Inside all vestiges of the road car are gone. The cockpit is dominated by it’s quick release steering wheel and massive sequential gear stick. It’s yours for a cool 279,000 euros in basic trim without taxes…
