The 911 GT3 R Hybrid images and information recently made a world debut. Developed specifically for racing and hoping to continue the Porsche 911 race-winning pedigree, the GT3R’s 480bhp four-liter flat six rear-wheel drive is assisted by two front hub-mounted 60kW (80hp) electric motors.
In a novel approach, a 40,000rpm electric flywheel power generator supplies 120kW of electrical power to the electric motors for a duration of around 6-8 seconds, this power is available immediately after being charged with power from the front hub motors during regenerative braking.
The braking inertia is converted into electromagnetic energy and stored as rotating kinetic energy in the flywheel, and back again into electrical energy under acceleration – perfect for a racing car to brake for a bend and then accelerate through it. This provides extra power and reduces fuel consumption, resulting in a lighter fuel tank and less pit-stops during a race.
Testing will include a 24 hour race on the Nordschleife of Nürburgring this May 15th and is part of Porsche’s “racing laboratory” - proving hybrid technology in road-going sports cars, leading to lower fuel consumption, lower CO2 emissions and more fun-per-hybrid-brakehorsepower.
As an historical footnote, around 110 years ago Ferdinand Porsche developed the world’s first hybrid drive car called the Lohner Porsche which had two internal combustion engines, electric hub motors on the front wheels and stored energy in a battery.
