Costs & verdict
Everyday costs, plus how reliable and safe it is
Costs, insurance groups, MPG and CO2
The entry-level V6 Cayenne and the V8 Cayenne S are in the top bracket for benefit-in-kind tax, so both will be astronomically expensive to run as a company car. The E-Hybrid version is much more attractive on this front thanks to its relatively low CO2 emissions and decent pure electric range. The Range Rover Sport P440e is even cheaper to run as a company car though.
If you're buying privately, the pure petrol versions make far more sense and should hold onto their value well. This helps make monthly PCP repayments a little more palatable. Just don't expect cheap fuel bills – you'll be lucky to average much more than 20mph in the V8 Cayenne S.

Reliability
Overall, the Porsche brand finished joint 19th (alongside Tesla) out of 32 manufacturers in the 2022 What Car? Reliability Survey. That’s below Volvo and BMW, but above Audi, Mercedes, Jaguar and Land Rover.
For peace of mind, the Cayenne comes with a three-year, unlimited-mileage warranty, which is par for the course in this class. You get European breakdown cover for the first three years of ownership too.
