2020 Audi A8 Quattro

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 A8 Quattro.

The 2020 Audi A8 Quattro is a long-wheelbase luxury sedan that combines a 55 TFSI engine with the brand’s signature Quattro all-wheel-drive system, running on 0W-20 oil.

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 2020 Audi A8 Quattro dominate in one area — the engine, 1 of 3 reports (33%), well ahead of the next concern. That matters, because the engine are also the target of recall 21V-111 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 0 of the reports describe a crash and 1 a fire — a small share of the total, but worth weighing against the engine 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.
