"Spontaneous response, lightning-fast revving and a unique sound - the heart of the Audi R8 is its naturally aspirated V10 engine. In the base unit, output increased from 397 kW (540 hp) to 419 kW (570 hp), while torque grew by 20 Nm to 560 Nm, available at 6,200 rpm. As a result, the Audi R8 V10 quattro accelerates from 0 to 100 km/h (62 mph) in 3.4 seconds (Coupé) or 3.5 seconds (Spyder) and on to a top speed of 324 (322) km/h (124 mph). In the Audi R8 V10 performance quattro, the 5.2 FSI produces 456 kW (620 hp) instead of the previous 449 kW (610 hp), and its torque peaks at 580 instead of 560 Nm. The increase here results primarily from an optimized valve train with components made of titanium. The Coupé sprints to highway speed in 3.1 seconds, while the Spyder needs 3.2 seconds. Propulsion does not end until 331 (329) km/h. The two naturally aspirated V10 engines with 5.2 liters of displacement receive a particulate filter. "
