Technical Background The R8 has the steering dynamic of a sports car. The inner and outer wheels are turned at approximately the same steering angle to ensure even power distribution through the front self-locking differential during high speed cornering. This steering dynamic minimizes understeer and ensures vehicle stability in high-speed turns. Under normal conditions, when the vehicle is maneuvered through tight turns at slow speeds (such as while parking), the steering angle difference between the inner and outer wheel is not noticeable because the side wall flex of the tire is sufficient to compensate. Contact with the road surface is maintained. © 2024 Audi of America, Inc. Internal Page 1 of 2 All rights reserved.

Technical Service Bulletin However, under certain conditions (such as cold weather, wet/dirty pavement, or a long parking period), a front tire can scrub. The customer may report a shudder or a skipping sensation felt in the steering/front suspension of the vehicle during slow-speed parking maneuvers. This is normal performance for the sports car steering dynamic in the R8, and no repairs are required. Production Solution Not applicable. Service Explain the technical background to the customer.
