The A6 based allroad concept hints at the design elements of the next production allroad. Audi claims that the allroad concept's 4.0L V-8 TDI is the most power turbodiesel available. Performance is comparable to similar gasoline powered vehicles. Performance is brisk: 0-100 km/h (62 mph) in 6.4 seconds, with a governed top speed of 250 km/h (155 mph). An adjustable ride height air suspension, combined with conventional dampers, provides optimized ground clearance and handling for any road conditions. LED headlights offer comparable light to xenon beams. Audi side assist uses radar sensors to warn the driver of approaching vehicles and even covers vehicle blind spots.
