    Located just to the right of the driver, where a passenger seat would normally be situated, is a large charcoal gray carbon fiber case. This again increases the efficiency and, accordingly, the performance of the GT3 R Hybrid, for example by reducing the weight of the tank or making pitstops less frequent. Passing the apex of the next corner I mash the throttle and hold on. In layman's terms, normally wasted heat energy in braking is converted to electricity and sent back to the pavement when accelerating out of a corner or overtaking another race car via twin 75 kW horsepower motors located on the front driveshaft.

    Hybrids, if this monster of a machine is anything to go by, are quite clearly the future for companies like Porsche and Ferrari et al. Some people said they would never catch on but look where we are now. And for road car use? In simple terms the GT3 RH uses a conventional bhp flat six engine mounted at the back, powering its back wheels, while over the front axle it has a further pair of 60kw electric motor that power the front wheels, each developing 80bhp.

    Which means it has bhp in total. And when you press the magic button, with the flywheel spinning at up to 40,rpm, it then redeploys the stored power back to the front axle wheels and, presto, you get a monster great hit of acceleration for seconds — perceptible in any gear, and at any speed. The really clever bit, though, is that it generates its power almost exclusively via the brakes, not via the engine or a bank of batteries, as in the F1 systems.

    And this means it can regenerate full power almost as fast as you can burn it. One big stop from sixth to third gear and you can virtually recharge the system — and that makes it much more efficient than the KERS that was used in F1.

    Quite spooky, incredibly efficient but also just very, very exciting to use. When you press the magic button for the first time it actually feels a bit like a cheat, the rush of extra acceleration comes at you that fast. But when you get used to the way it works — the way it can alter not just your speed along a straight but also the handling balance mid corner even — the hybrid GT3 R is quite clearly a highly significant piece of kit; the beginning of a brand new era. In practice, the system recharges so fast that it is constantly available, simply because unless you forget to press the brakes for some strange reason, you are always recharging the system.

    One, weight; all up the system adds kg to the weight of a regular GT3 R kg. Two, at the moment the only way to ensure that a proper recharge takes place is to brake very hard indeed. The ease with which the system generates and then gives back its power is genuinely incredible. In the end they gave me six laps in the car, three with the hybrid system off, three with it on. On laps one, two and three I drove fairly hard and enjoyed the GT3 R for what it is; one of the most successful cars in modern GT racing.

    It was faster and more brutal than I was expecting in some ways, more delicate and touchy-feely than I had anticipated in others. I could tell the system was fully primed because, during the previous three laps, a row of green Christmas tree lights had gradually started to illuminate on the left hand side of the dash.

    At the same time my passenger — that huge flywheel, the motor — had started to make louder and stranger noises; it sounded like some kind of crazed hoover that was spinning faster with every second. The first time I pressed the button, half way along the main straight, it really did feel like an extra lb ft had been instantaneously released.

    There was no great audible change of timbre, except for the fact that the revs rose faster than previously. It felt literally like some enormous unseen hand had attached itself to the back of the car and given it a great big shove. No matter, because hybrid power is not the future for companies like Porsche and cars like the , it is the present. Not so much the end of the road for high performance cars, but the beginning of a brand new chapter.

    I an keen to see nissans latest technology response as i'm sure they would like the GTR to stay ahead of Porsche in performance terms. Trouble is flywheels require mass to work. There will be limits to how much weight can be lost. The systems needs to provide a positive overall. If the flywheel adds extra weight, and say increases lap times by 2 seconds a lap over a normal car, yet when in use reduces lap times by 4 seconds then it provides a benefit.
