TCC’s Bottom Line
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. The 2018 BMW 5-Series expands the sedan's already-excellent lineup to include an efficient plug-in hybrid and an uber-quick V-8. The 2018 Mercedes-Benz E-Class goes to excess--the right kinds of excess--to preserve its best-of status.
