Mid-engine 918 RSR is a high-tech test bed for future technology<\/strong><\/p>\n

DETROIT \u2013 January 10, 2010 — With the world debut of the spectacular 918 RSR \u201cracing lab,\u201d Porsche AG today highlighted its continued and intensive focus on combining ultimate performance and high efficiency in the field of hybrid technology. The fourth hybrid vehicle presented by Porsche in the last twelve months, the extreme two-seat coupe reveals what happens when the technology fitted to the 911 GT3 R hybrid and the design of the 918 Spyder are fused to a modern, innovative super sports car.<\/p>\n

Flywheel technology from the GT3 R Hybrid race car<\/strong><\/p>\n

With its highly-efficient flywheel accumulator, the 911 GT3 R Hybrid racing car was an attention magnet on Germany\u2019s N\u00fcrburgring Nordschleife, America\u2019s Road Atlanta and China\u2019s Zhuhai racetracks. It demonstrated its performance potential under racing conditions against very tough competitors, showing competitiveness, high reliability and exemplary fuel efficiency combined with extraordinary performance.<\/p>\n

Like that car, the 918 RSR \u2013 the motorsports-oriented version of the 918 Spyder \u2013 obtains its additional power from its own vehicle dynamics under braking.\u00a0<\/p>\n

The 918 RSR\u2019s mid-mounted V8 engine is a development of the direct-injection engine from the successful RS Spyder race car, and now offers an output of 563 hp at 10,300 rpm. Two electric motors powering the front wheels each contribute 75 kW; leading to a peak power output of 767 hp from the hybrid system.\u00a0<\/p>\n

At the front axle, the two motors offer a torque-vectoring function to increase agility and improve steering response. Ahead of the rear axle, the mid-mounted engine is integrated with a racing transmission based on the RS Spyder. This six-speed constant-mesh transmission with longitudinally-mounted shafts and straight-toothed gears is operated using shift paddles behind the racing steering wheel.\u00a0<\/p>\n

Power generated during braking is stored in an optimized flywheel accumulator, an electric motor whose rotor rotates at up to 36,000 rpm to store energy. Charging occurs when the electric motors on the front axle reverse their function during braking. When the driver needs additional power for acceleration or overtaking, the push of a button calls up the stored energy, deploying it in bursts of up to eight seconds when the system is fully charged.\u00a0<\/p>\n

As in the successful 911 GT3 R Hybrid, the additional power can also be used to reduce fuel consumption by lengthening the amount of time between pit stops.<\/p>\n\n\t\t
