This car has racing genes. And you can feel them on the road. Like practically no other sports car, the Audi R8 Spyder offers the feeling of unmediated control over almost limitless power. Feel the irresistible acceleration: choose between a 4.2 l V8 FSI engine with 316 kW and the 5.2 l V10 FSI engine with 386 kW.
Thanks to the mid-engine design, the engine weight is near the vertical axis, thus ensuring a balanced distribution of axle load. This results in neutral driving behaviour and outstanding road handling. The dry sump lubrication makes reliable oil supply possible at high lateral acceleration forces. In addition, the flat oil sump allows the engine to be installed lower, bringing the vehicle’s centre of gravity closer to the ground.
The high-rev concept (HRC)
The meaning behind this technical term is pure driving enjoyment derived directly from motorsport. The high-rev concept in the V8 and V10 mid-engines of the Audi R8 works according to a simple principle. An increased number of combustion processes in the cylinders creates more power and therefore a greater power yield. With the V10 engine in the R8 V10 Spyder, for example, the maximum speed is at impressive 8,000 rpm and its maximum power output is 386 kW. Yet even at low speeds, the long-stroke units drive powerfully forward. The torque curve of the V10 power unit reaches a maximum value of a full 530 Nm. In the R8 V10 Spyder with S tronic, this will enable you to spurt from 0 to 100 km/h in only 3.8 seconds. The propulsion only ends at 311 km/h. With 4.1 seconds for the spurt from 0 to 100 km/h and a maximum speed of 313 km/h, the R8 V10 Spyder with its 6-speed manual gear also achieves impressive values.
The resulting vibrational and thermal stresses are restrained by the compact, high-strength design of the lightweight aluminium engines. In conjunction with the dry sump lubrication used in motorsport, high lateral acceleration forces are also possible. A low oil sump with oil pump module and a separate oil tank ensure an even supply of oil to the engine. In addition, the flat oil sump allows the engine to be installed lower, bringing the vehicle’s centre of gravity closer to the ground.
The FSI principle
The direct fuel injection technology FSI, which we have also brought from the racing track to the road, works in all engine variants. The FSI technology directly injects the fuel into the combustion chamber where it is highly compressed. This produces a very even fuel/air mixture, leading to particularly efficient combustion and therefore to a better power delivery and power yield. The V8 power unit in the Audi R8 reaches its maximum torque of 430 Nm between 4,500 and 6,000 rpm with 90% of the power already being available at an even wider engine speed range between 3,500 and 7,500 rpm. This spontaneity allows the R8 V8 Spyder with S tronic to sprint from 0 to 100 km/h in only 4.5 seconds. Moreover, the mid-engine sports car design means that the mass of the vehicle is concentrated close to its centre of gravity, for very good distribution of axle load and a balanced driving performance. The performance of the engines with their spontaneous responsiveness, the even power delivery and enormous speed willingness is accentuated by a powerful sound backdrop that will thrill you over the entire rev range.
