Overview

The 2018 Audi A8 L is a full-size sedan offered in a single trim, starting off at a base MSRP of $82,500. For that price, it mainly competes with the BMW 7 Series, the Mercedes-Benz S-Class Sedan, and the Jaguar XJ. The A8 L offers 2 powertrains. The base engine is a 3.0L supercharged V6 engine capable of making 333 horsepower and 325 lb-ft of torque. If more power is required, there is also a 420 horsepower-making 4.0L turbocharged V8 engine. Both engines are mated to an 8-speed automatic transmission.

The A8 L reaches 60 mph from zero in 5.3 seconds on its base engine, which gets pumped up to 4.2 seconds with the V8 engine. Depending on the powertrain, the A8 L can manage a combined fuel economy between 19 and 22 mpg. While we’re on the topic of choices, the 10 striking colors the A8 L comes in really pull you towards itself. Check out the video below by "The Wheel Network" for a detailed review of the 2018 A8 L. 

Buying Advice

The 2018 Audi A8 L is a strong and refined sedan that has a luxurious cabin. Among the powertrains on offer, we recommend going for the V8 which is more powerful and smooth. Along with this, we recommend adding the Rear Seat Comfort package that adds power outboard rear seats with power lumbar adjustment, ventilated outboard rear seats with massage function, and front-passenger seat power adjustment from the rear seat.
