Optional with the V-8 may be a more advanced active suspension that scans the road ahead for bumps and takes measures to compensate. An adjustable air suspension and driver-adjustable adaptive dampers are standard. The A8 offers a really Audi-like blend of athleticism and ride comfort. The Audi's engine is smooth, but there is no fanfare to its power delivery, and sound-deadening measures are so extensive that it's practically inaudible with the windows up. Among six-cylinder executive sedans, that's on par with the Mercedes-Benz S450 but a couple of tenths off the rapid pace of the BMW 740i.

So far, we've only tested the V-6 55 TFSI version, which sprinted from zero to 60 mph in 5.3 seconds at our test track. The 2021 Audi A8 TFSI e is rated at 443 hp. The plug-in hybrid 60 TFSI e combines the V-6 with an electrical motor and a rear-mounted 14.1-kWh battery pack. An eight-speed automatic drive and all-wheel drive are standard. Both versions use a 48-volt hybrid system.

The base 55 TFSI comes with a turbocharged V-6 rated at 335 horsepower, and therefore the 60 TFSI features a 453-hp twin-turbo V-8 engine.
