"The Audi A8 is quiet, comfortable and luxurious, but packs huge performance and can be fun to drive when you want it to be."
If you’re lucky enough to drive an Audi A8 – or if you’re even luckier and are chauffeur-driven around in one – then you’ll quickly realise just how impressive this car is. It's loaded with a host of clever technology to make the driving experience as comfortable and luxurious as possible, including lights that are connected to the sat nav so they can illuminate junctions, bend round corners and even dip when they detect oncoming traffic. The inside of the car is classy and solidly build and the engines available mean the car is quick whichever model you buy.
The entry-level A8 is the 258bhp 3.0-litre TDI diesel and in truth this engine makes the car as quick as anyone is ever likely to need. A more powerful 4.2-litre TDI is also available, while the blisteringly quick S8 has a 4.0-litre twin-turbo petrol engine that produces 513bhp. If you go for the long-wheelbase version, with more space for rear passengers, you can also choose a hybrid version or the W12, which has the huge 6.3-litre petrol engine also found in the Bentley Continental.
Combined with the A8's vast size, the more powerful engines aren’t cheap to run, but if you stick with the diesels, official fuel economy figures are nearly 50mpg.
All Audi A8s come with quattro four-wheel drive and a system called Audi Drive Select that allows you to tweak the steering, suspension and gearbox to make the car sportier or more comfortable, giving you the flexibility to change the car's character depending on how you want to use it. The interior boasts the highest-grade materials and is very logically laid-out and easy to use. While the boot isn’t the biggest in this class, there's room for several suitcases and even more space and storage inside the car for passengers.
Customers looking for even more space to stretch out in the rear can choose the long-wheelbase version, which provides limousine-like legroom for back-seat passengers. The Audi A8 comes in SE, SE Executive, Sport and range-topping S trim levels, while the long-wheelbase version comes in L SE, L SE Executive, Hybrid and W12 specifications.
The Audi A8 counts the Mercedes S-Class, BMW 7 Series and Jaguar XJ as its main rivals, and while the Mercedes is more comfortable, the BMW slightly better to drive and the Jaguar more eye-catching, the Audi is still an excellent all-rounder, with arguably the best interior in the class.
If you’re looking to buy an Audi A8, we’d recommend the 3.0-litre TDI model in SE trim. Although it's the most basic version, there's nothing basic about the standard equipment or performance on offer.
