How these Porsche figures are worked out
Each model uses its manufacturer combined economy — 235 ÷ L/100 km gives the US MPG we price against — multiplied by 12,000 miles a year and the current US national average of $4.27/gal for regular, $6.35/gal for diesel and $0.17/kWh for home charging. Prices refresh on each source's own schedule, so these numbers move with the market — see methodology. Not affiliated with Porsche.

Are these Porsche fuel economy figures real-world?
They are manufacturer combined-cycle figures — WLTP in Europe, EPA combined in North America — which is the only basis on which every model can be compared like for like. Real driving is typically 5–15% thirstier, more in cold weather and city traffic, so treat these as the ranking rather than the guarantee.
