The Car Connection's Take
TCC Rating
8.2
7.6
TCC’s Bottom Line
As much a track star as it is a comfortable daily driver, the 2018 Audi R8 is one of the most balanced and flexible supercars ever made. The 2018 Porsche 911 is a superlative sports car that has defied its age. It’s a classic, but performs better than nearly any newcomer to its arena.
