The Car Connection's Take
TCC Rating
7.0
7.2
TCC’s Bottom Line
The 2021 Audi Q8 is an expansive–and expensive–full-size luxury crossover that doesn’t cut corners, it carves them. The 2020 Porsche Cayenne offers hybrid models, but fuel economy isn’t its best look. For that you’ll want to check out the new Taycan electric car.
