TCC’s Bottom Line

Only poor crash test scores keep the Grand Cherokee down, as this talented family hauler offers luxury and utility and buyers can choose off-road capability, track talent, or even more luxury.

The 2018 Porsche Cayenne is a richly appointed luxury SUV that earns its Porsche badge. It's one of few cars on the road that manage to feel special in standard or top trims, despite a $100,000 price difference.

TCC Likes

Premium look and feel
Responsive 8-speed automatics
SRT and Trackhawk are fit for track time

Strong engines
Superlative handling for the big SUV
Lots of options to consider

TCC Dislikes

Quite pricey, to be without a luxury badge
Grille design still not in alignment
Hemi is too thirsty for what it provides

Not particularly efficient with space inside
Base model isn’t really thrilling
Unbelievably expensive options
