Used 2018 Audi A8 Sedan Trims Comparison

Trim level differences

The 2018 Audi A8 is a flagship luxury sedan comes in a single, long-wheelbase L body style — hence the name A8 L. There are two trim levels available, each corresponding to a different engine. The A8 L 3.0T has a supercharged 3.0-liter V6 good for 333 horsepower and 325 pound-feet of torque. The A8 L 4.0T has a turbocharged 4.0-liter V8 good for 450 hp and 444 lb-ft of torque. All A8 models come with an eight-speed automatic transmission and all-wheel drive.

The A8 L 3.0T comes standard with 19-inch wheels, an adaptive air suspension, LED headlights, a sunroof, heated and power-folding mirrors, auto-dimming mirrors, parking sensors, a rearview camera, power door closers, a power trunklid, and keyless ignition and entry.

Inside, you get four-zone automatic climate control, leather upholstery, extended leather interior trim, 14-way power-adjustable front seats (with heating and four-way lumbar adjustment), driver-seat memory settings, a power-adjustable steering wheel and power rear sunshades. Standard electronic equipment includes Audi's previous-generation MMI infotainment interface, a navigation system, 4G LTE Wi-Fi, Bluetooth, voice controls and a 14-speaker Bose surround-sound audio system with a CD player, satellite radio, a media player interface and one Audi proprietary power/information port for smartphones. There is no USB port.

The A8 L 4.0T adds the V8 engine, 20-inch wheels, additional sport-themed styling tweaks, a panoramic sunroof, diamond-stitched leather upholstery, simulated suede headliner, 18-way adjustable multicontour front seats (with ventilation and massage), a heated steering wheel, heated rear seats, a trunk pass-through, a top-view parking camera and a head-up display.

The 3.0T can be specified with the Executive package, which includes the 4.0T's 20-inch wheels, a panoramic sunroof, multicontour front seats, heated steering wheel and rear seats, trunk pass-through, a top-view parking camera and head-up display, along with adaptive cruise control, a forward collision warning system (Audi Pre Sense Plus), lane departure warning and intervention, and automatic high beams. Those driving aids are included in the 4.0T's Executive Plus package, which also adds power-adjustable outboard rear seats (with ventilation, massage and lumbar adjustment).

Both trims can be specified with a Black optic package, which adds a variety of dark exterior pieces and a choice of 20- or 21-inch wheels.

Which A8 trim does Edmunds recommend?

We like the 4.0T. It provides impressively quick acceleration and gets the same fuel economy as the V6. Plus, the 4.0T's exterior design flourishes also serve to spruce up the A8's rather conservative look while maintaining an impeccable taste level. Specifying the Executive Plus package (or the Executive package on 3.0T) is recommended for its helpful driver aids and extra luxury features.
