The Car Connection's Take
TCC Rating
8.4
7.2
TCC’s Bottom Line
The 2015 Audi A6 may look a little sedate, but it's a brilliant performer–thanks to its diesel-driven TDI, the supercharged A6, or turbocharged S6 versions. The 2018 Infiniti Q70 stands alone as a warm take on luxury that others have left behind. It’s not as luxurious as the others—but it’s not as expensive as those, either.
