The Car Connection's Take
TCC Rating
9.0
9.4
TCC’s Bottom Line
The Audi A8 gains standard LED headlamps, a more powerful twin-turbo V-8, and a more efficient diesel engine for 2015. With the addition of a beautiful, expressive new Coupe, the 2015 Mercedes-Benz S-Class is no longer just the best sedan in the world; it's now a family of flagship models.
