The Car Connection's Take
TCC Rating

TCC’s Bottom Line
The 2017 Audi S8 is the super sedan by which others are measured. The 2017 BMW 7-Series has a deceivingly conservative wrapper for its radically reengineered underpinnings and tech-centric cabin. The Mercedes-Benz S-Class lineup is more diverse than it's ever been and is still the benchmark by which all full-size luxury cars should be measured.
