Design & Size
Engine & Performance
Too close to call
You can skip ahead if engine & performance was your deciding factor: the two are evenly matched here. This section won’t settle the choice, so weigh the other areas more heavily.
Fuel Economy & Range
Too close to call
The fuel economy & range section is even. Any gaps here are within the range you’d never notice. For fuel economy & range, pick whichever you prefer for other reasons.
Space & Practicality
Too close to call
Neither the Q8 nor the Cayenne has a real advantage in the space & practicality category. The takeaway: space & practicality is not where these two differ.
Off-road & Towing
Too close to call
Evenly matched is the fairest summary of the off-road & towing section. Neither car gives you a reason to choose it on off-road & towing.
