Porsche Taycan GTS
What it costs to keep fuelled
$558a year, fuel only
The 2026 Porsche Taycan GTS is EPA-rated at 86 MPGe combined (88 city / 85 highway). Over 15,000 miles a year that is about 174 gallons, $558 a year in fuel, or $0.037 per mile at $3.20/gal.
Across its full 2022–2026 run it averages 84.2 MPGe, improving by 3 MPGe over 5 model years.
The band is how far one gallon-equivalent of energy carries it: 86 of the 120 MPGe this scale runs to. The square tick is the compact cars average, 26.3.

How this is worked out
- Start from the EPA combined figure for the model year — a laboratory test cycle run to a fixed procedure, not a road result. Where a year sold several engines or drivetrains, the trims are averaged and the trim count is printed beside the row so you can see how much averaging is behind it.
- Fix a pump price. This site keeps one reference price, $3.20 a US gallon, fixed JUL 2026 and printed next to every dollar figure it produces. It is an assumption with a date on it, not a quote — put your own price in.
- Fix an annual distance. Every annual figure on this site uses 15,000 miles a year, roughly the US average. A cost per year with no stated distance is not a number, it is a mood.
- Divide distance by economy for gallons, multiply by price for the year's fuel, divide price by economy for one mile. The per-kilometre line is that last figure divided by 1.609344 — the same money, in the unit most of the world drives in.
- Stop there. No depreciation, no tyres, no insurance, no servicing. This is the fuel line of the ledger and it is labelled as one; depreciation usually dwarfs everything on it.
gallons/yr = miles/yr ÷ MPG fuel $/yr = gallons/yr × $/gal cost $/mi = $/gal ÷ MPG cost $/km = cost $/mi ÷ 1.609344

Re-run the ledger at another pump price
Every line above rests on one pump price. Here is the same entry re-costed at six others, because the price is the part that changes while the test sheet stays put.
| Fuel price | Per mile | 10,000 mi/yr | 15,000 mi/yr | 20,000 mi/yr |
|---|---|---|---|---|
| $2.50/gal | $0.029 | $291 | $436 | $581 |
| $3.00/gal | $0.035 | $349 | $523 | $698 |
| $3.20/gal | $0.037 | $372 | $558 | $744 |
| $3.50/gal | $0.041 | $407 | $610 | $814 |

| $5.00/gal | $0.058 | $581 | $872 | $1163 |
This is an electric vehicle, so the EPA rates it in MPGe — the distance it travels on the energy equivalent of a gallon of petrol. The dollar figures above are a petrol-equivalent illustration only; charging at home is billed per kWh and is normally far cheaper. Treat the MPGe as an efficiency comparison, not a fuel bill.
