The Audi R8 Spyder 5.2 FSI quattro, which was developed in cooperation with quattro GmbH, dazzles with uncompromising performance. The V10 engine with the aluminum crankcase, much of which is hand-built, follows in the grand motorsports tradition at Audi. The normally aspirated engine produces 530 Nm (390.91 lb-ft) of torque at 6,500 rpm. Peak output of 386 kW (525 hp) is reached at 8,000 rpm, and the rev limit is not reached until 8,700 rpm. Specific power output is 100.9 hp per liter of displacement; each hp only needs to move 3.3 kilograms (7.28 lb) of weight.
Performance reflects this awesome potential: 0 – 100 km/h (62.14 mph) in 4.1 seconds; 0 – 200 km/h (124.27 mph) in 12.7 seconds; top speed is 313 km/h (194.49 mph) with the six-speed manual transmission. As load and revs increase, the engine unfolds the rich, unmistakable Audi ten-cylinder sound – a powerful, throaty roar with musical undertones.
The 5.2-liter engine features FSI direct fuel injection. The high 12.5:1 compression ratio that this enables contributes to the high performance and good fuel efficiency. Equipped with a manual transmission, the R8 Spyder 5.2 FSI quattro consumes an average of 14.9 liters of fuel per 100 km (15.79 US mpg) – a good figure given its power. With R tronic, this figure improves to 13.9 liters (16.92 US mpg). Dry sump lubrication, another motorsports technology, ensures that the supply of oil is maintained even at the maximum lateral acceleration of 1.2 g.
The Audi R8 Spyder 5.2 FSI is also available with an optional automatic six-speed transmission. The R tronic offers a normal and a sport program as well as a fully automatic and a manual mode. The manual mode allows the driver to make lightning-fast gear changes using the joystick on the center tunnel or with the paddles on the steering wheel. The open-air sports car also comes with “Launch Control” – a program that manages engagement of the clutch perfectly to maximize acceleration at start.
The quattro permanent all-wheel drive features a central viscous coupling and distributes power to all four wheels with a heavy rear bias. It works together with the locking differential on the rear axle to provide significantly greater traction, stability, cornering speed and precision. It is the superior technology – in particular for a high-performance sports car.
