2017 Audi A8/S8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2017 A8/S8.

Body PASSENGER CAR

The 2017 Audi A8 and S8 represent Audi's full-size luxury sedan offerings in the passenger car segment, requiring 7.2 quarts of engine oil for maintenance, a specification that reflects the substantial powertrains powering these vehicles; with only six total owner complaints filed across the model year and three recalls, the 2017 model stands out as a notably cleaner reliability record compared to surrounding model years, though the concentrated complaint areas in Vehicle Speed Control and Service Brakes suggest prospective buyers should verify the resolution status of any related recall work before purchase.
