The Car Connection's Take
TCC Rating
8.8
8.8
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.
