With a considerable price tag, Porsche Panamera running costs aren’t cheap but it does hold its value well so you’ll get a large chunk of what you initially spent if you decide to sell or trade in for a newer model. Fuel economy isn’t a strong point for petrol models (the Turbo returns an average of just 23mpg) but the diesel returns a reasonably healthy 43.5mpg on average.

As you’d expect, insurance is extortionate. On the plus side, service intervals are lengthy with a minor service required every 20,000 miles or two years. Porsches traditionally hold on to their resale values well. The diesel model depreciates the least while, predictably, the Turbo variants lose the greatest percentage of their value over time. The Hybrid is also susceptible to a greater rate of depreciation than other Panameras but its 159 g/km CO2 figure means it dips under the Company Write Down Allowance threshold of 160g/km allowing its price to be offset against tax at 20% per annum for fleet and company car drivers.

A large four-seater sports car with a V8 engine is never going to be particularly environmentally friendly but Porsche has made efforts to reduce CO2 emissions. For best Porsche Panamera emissions go for the Hybrid with 159g/km but the diesel isn’t bad either with 172g/km. PDK models come with a start/stop function which cuts the engine in traffic and then automatically restarts again when moving off.

This means that the standard S fitted with the PDK gearbox emits 253g/km of CO2 and averages 26mpg. Surprisingly, that’s competitive with other large saloons with similar power.

Porsche Panamera reliability is excellent. The German sports car maker has a superb reputation for high quality engineering and the Panamera is no exception. If the unlikely should happen and anything does go wrong, you’ll be dealing with dealerships which offer superb customer service.
