2018 Audi A8 vs. Its Competition

2018 Audi S8
Aaron Cole Aaron Cole Managing Editor

The Audi S8 competes in rarefied air with the BMW Alpina 7 and Mercedes-AMG S63.

Both are newer cars with updated tech, but all three are relatively on par when it comes to performance.

None of the three are particularly flashy, but the S8 is even more subdued—almost to a fault.

The Jaguar XJR and Lexus LS F-Sport may not turn the same lap times, but they can turn heads.

There’s not a bad pick among them, but the Lexus is quickly approaching a newer version.
