Porsche Panamera (2016 - 2024) – MPG and running costs
Standard V6 and V8 models are thirsty, but make use of the E-Hybrids’ battery pack and it will hike up the MPG
Panameras are inherently big and heavy cars, which means even in hybrid form they use an alarming amount of premium unleaded. All pure-combustion models are, erm, not very efficient, with even the entry-level Panamera rear-wheel drive using between 25 and 27mpg – a figure that’s consistent between 4 and 4S models, too.
The V8 GTS and Turbo S drop this to between 21 and 23mpg, a figure we found to be pretty accurate when pootling around town. Make use of the Turbo S’s extra performance and expect this figure to drop into the teens – or even lower…
But the hybrids save the day, right? If you can consistently charge up the batteries every 20 miles or so, they can largely run on the electric motors alone, and even if they're charged a little more sporadically, they’ll always help the overall MPG figures. On paper, these generally sit between 100 and 141mpg for the V6s, and around 100mpg for the V8, but run out of electrical juice and things look very different.
Despite the low-speed electrical assistance that remains when the batteries run out of electricity, the reality of a 2.2-ton-plus car with a turbocharged petrol V6 or V8 engine becomes reality, causing the MPG to drop like a stone. Drive with a bit of purpose and this process will get even more prominent.
Aside from fuel, running costs are set to be high, even by Porsche standards. For this you can thank the outright size of the components. Wheels, tyres, brakes, oil – any consumable really that the Porsche can chew through, so it will quickly.
