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.

TCC Likes

Great space
Superlative performance versions
Good tech

Performance, meet SUV
Sleek interior finally ditches the buttons
High level of personalization

TCC Dislikes

Conservative style
Eye-watering price tag on top trims
Not very fuel-efficient

Big SUV with a penchant for fuel
Might be too stiff for some, even in its softest settings
Porsche excellence comes with Porsche pricing
