Monsoon Gray Metallic 2018 Audi A8 L 3.0T quattro quattro 8-Speed Automatic with Tiptronic 3.0L V6 Turbocharged DOHC 24V ULEV II 333hp Brown Leather. 29/19 Highway/City MPG

Audi 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.
