New Audi A8 vs Mercedes S-Class

Our verdict

The S-Class wasn’t going down without a fight and, after the recent facelift, it’s as good a luxury car as it has ever been. It has a strong yet smooth diesel engine, is more agile than the A8, has a better infotainment system and is the cheaper option for most buyers. The S-Class very much deserves its five-star rating.

So it was always going to take an extraordinary luxury car to dethrone the S-Class. But we have one in the A8. It manages to feel even sturdier inside, is quieter on the move, has an even plusher ride and comes with more standard equipment. The A8 has certainly earned the right to waft past the S-Class to take the win in this test.
