Audi R8 | Part Three
Audi R8 quattro system
The sophisticated dampers fitted as part of the optional Audi magnetic ride system swap conventional damper fluid for a magnetorheological fluid containing minute magnetic particles that can be influenced by an electromagnetic field. By applying a voltage to the system’s electromagnets, the viscosity of the fluid is altered by the affected magnetic particles, increasing resistance to damper movement to iron out pitch and roll when necessary, and reducing resistance when ride comfort takes precedence. The system constantly monitors road conditions and driving style and reacts accordingly.
quattro four-wheel-drive reassurance
The relationship between the road and the 19-inch 5 double spoke design alloy wheels - fitted with 235/30 size tyres at the front and 295/30 size at the rear - is made crystal clear at all times by the fast-reacting hydraulic rack-and-pinion steering. That relationship is also constantly moderated by the legendary quattro permanent four-wheel-drive system, which by apportioning power to front and rear axles in constantly varying degrees dictated by road conditions prevents the tendency for ‘waywardness’ sometimes exhibited by powerful mid-engine, rear-drive sports cars. An electronically activated rear spoiler also deploys when sensors detect that composure at higher speeds would benefit from additional down-force.
