2015 Audi A7/S7/RS7 Quattro

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 A7/S7/RS7 Quattro.

Body PASSENGER CARTransmission Automatic (S8)

The 2015 Audi A7, S7, and RS7 Quattro are premium passenger cars that share a sophisticated all‑wheel‑drive platform, an automatic S8 transmission, and a generous 7.2‑quart engine oil capacity with 5W‑40, 5W‑30, or 0W‑40 options. Their EPA fuel economy ranges from 24 to 38 mpg in the A7, 29 mpg in the RS7, and 24 mpg in the S7, reflecting the varying powertrains across the range. With only five total owner complaints—most notably a “Service Brakes” issue—and three recalls recorded for that model year, the 2015 lineup sits on a relatively clean reliability record, suggesting a solid but not fault‑free foundation for further analysis.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2015 Audi A7/S7/RS7 Quattro dominate in one area — the service brakes, 2 of 5 reports (40%), well ahead of the next concern. None of this vehicle's 3 recall campaigns target the service brakes, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the service brakes pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
