Edmunds' Expert Review
Overall rating
Other German luxury sedans have endeavored to be flashier and more opulent in recent years, wowing and often overwhelming occupants with state-of-the-art tech and showy displays of luxury. The 2018 Audi A8 takes a different path. It's a more conservative entry in the vaunted flagship luxury segment and pampers you without boasting to the world that you're being pampered. Perhaps that won't be for everyone in this day and age, but we think this more subdued approach has a lot of merit.
This generation A8 is entering its sixth year without a full redesign, however, and is behind the times in a few areas. Features such as Apple CarPlay, Android Auto and Audi's excellent Virtual Cockpit control interface are not available. Even a simple USB port isn't available; the A8 still uses Audi's older proprietary cable interface for connecting phones. A next-generation A8 is expected for 2019, and it will no doubt be fully up-to-date.
Overall, though, the 2018 A8 gives up little in terms of comfort, luxury and performance. The 4.0T engine, a 450-horsepower turbocharged V8, is of special note for its ability to sprint from zero to 60 mph in about 4 seconds while matching the 22 mpg combined of the standard V6. That engine is no slouch, but when you can get 117 more horsepower and the same fuel economy for a reasonable price premium, isn't it an easy choice?
Trim levels & features
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.

See your car's valueAudi interiors are often industry benchmarks so, as you might imagine, the cabin of the flagship 2018 Audi A8 sedan is a very pleasant place to be. From the supportive, massage-capable front seats to the roomy rear seats, this big Audi's accommodations are top-notch. Notably, Audi dropped the regular-length A8 a few years ago, making the previously optional A8 L the standard model. Much of the L's extra length is in the back seat and to call it limo-like wouldn't be an understatement — in fact, quite a few Audi A8Ls are used for executive transport. Don't let that fool you into thinking the A8 is slow or disconnected-feeling, however; Audi's largest sedan offers plenty of refined power and a rewarding driving experience.
The 2018 Audi A8 provides a choice of either a 340-hp, supercharged 3.0-liter V6 (3.0T) or a 450-hp, turbocharged 4.0-liter V8 (4.0T) that'll really get you moving. And should you want the fastest A8 variant in the stable, the Audi S8 cranks up the turbo V8 up to a dizzying 605 horses. Just keep in mind that the S8 comes only in standard-wheelbase specification, so you'll have to choose between maximum legroom and maximum performance.
With all models, the transmission is an eight-speed automatic, coupled with the Quattro all-wheel-drive system that adds an extra measure of safety and control, especially on slick pavement. Surprisingly, the V6 and the V8 both manage an EPA fuel economy rating of 22 mpg combined despite their decidedly different output numbers.
On the road, the A8's cabin benefits from excellent noise insulation. Handling is stellar for such a big car, although this sporty character means the ride is a bit firmer than the buttery smooth, magic carpetlike rides of its primary German competitors. The infotainment system includes an 8-inch touchscreen with a dial controller that connects you to an excellent sound system, among many other functions. Some of the controls take a little time to master and are a generation behind those found in cheaper Audis, but chances are they'll eventually make sense. You may even find them less complicated than controls in rival systems.
As nicely conceived as the 2018 Audi A8 is, though, there's an all-new one coming for the next model year that could be worth the wait. But if you're a fan of the current car — it's hard not to be — Edmunds can help you find the 2018 Audi A8 that fits your needs, at a price that's right for you.

Should I lease or buy a 2018 Audi A8?
Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
