The Car Connection's Take

7.0
TCC’s Bottom Line
The 2018 BMW M5 is equal parts performance monster and luxury cruiser. The 2018 Audi S6 stands with an impressive hand: quality interior, great performance, functional shape. It's possible to find better examples from other cars, but they all cost significantly more.
