The Car Connection's Take

TCC’s Bottom Line
The 2016 Audi S8 pairs thrilling acceleration with excellent big-car handling and discreet luxury. With the space of a larger car, the handling of a smaller car, and a starting price in the $50,000s, the CT6 is a large luxury car value. Coupe, Cabriolet, and Maybach versions—and even a Plug-In Hybrid—make the 2016 Mercedes-Benz S-Class far more diverse and adventurous than it used to be; it's now not just a flagship sedan, but a family of flagships.
