911 GT3 R Hybrid's World Debut in Geneva

The 911 GT3 R Hybrid is a perfect example of the Porsche Intelligent Performance philosophy, a principle to be found in every Porsche: More power on less fuel, more efficiency and lower CO2 emissions – on the track and on the road.

With Porsche's 911 GT3 R with innovative hybrid drive making its debut at the Geneva Motor Show, Porsche takes up another visionary driving concept into the future. The innovative hybrid technology featured in the car has been developed especially for racing, standing out significantly in its configuration and components from conventional hybrid systems. In this case, electrical front axle drive with two electric motors developing 60 kW each supplements the 480-bhp four-litre flat-six at the rear of the 911 GT3 R Hybrid. A further significant point is that instead of the usual batteries in a hybrid road car, an electrical flywheel power generator fitted in the interior next to the driver delivers energy to the electric motors.
The flywheel generator is charged whenever the driver applies the brakes, with the two electric motors reversing their function on the front axle and acting themselves as generators. Then, whenever necessary, that is when accelerating out of a bend or when overtaking, the driver is able to call up extra energy from the charged flywheel generator, the flywheel being slowed down electromagnetically in the generator mode and thus supplying up to 120 kW to the two electric motors at the front from its kinetic energy. This additional power is available to the driver after each charge process for approximately6 - 8 seconds.

Energy formerly converted – and thus wasted – into heat upon every application of the brakes, is now highly efficiently converted into additional drive power.
Depending on racing conditions, hybrid drive is used in this case not only for extra power, but also to save fuel. This again increases the efficiency and, accordingly, the performance of the 911 GT3 R Hybrid, for example by reducing the weight of the tank or making pitstops less frequent.

Porsche’s quest for speed never ends…

When the Porsche GT9 supercar hit 254 mph last year setting the official world record for the fastest speed on street-legal tires, it was considered a significant milestone. But as far as Porsche is concerned, that's already history and the future has already taken shape.

Brian Harris Porsche, your premier Porsche dealer in the Baton Rouge region is excited to bring you some thrilling bit of news!

This year, the 9ff is back with the new GT9-R that should hit 62 mph in just 2.9 seconds, then 186 mph in 15.8 seconds on its way to a top speed of 257 mph to claim the production car world record. And the GT9-R does it with only six cylinders.

The heavily modified, turbocharged 4.0L boxer six-cylinder motor will be seen in three levels starting at 750 hp, then 987 hp, and finally the full 1120 hp. This makes the base car good for a top speed of 236 mph and the mid-range build capable of a top speed of 254 mph. And the engine can be upgraded to the next power level at any time!
