UK company car tax

Benefit-in-kind tax is based on the official CO2 figure (63 g/km average for this model in the data), not on real-world use. Plug-in hybrids approved to the stricter Euro 6e-bis standard show higher official CO2. Under HMRC's current easement, qualifying cars first registered from 1 January 2025 to 5 April 2028 with official CO2 of 51 g/km or more and at least 1 mile of electric range are treated as 1 g/km for company car tax. Check your own car's emission standard and figures before relying on it.

Questions

How much fuel does the Porsche Panamera Turbo S E-Hybrid really use?

Across 425 cars in the EEA 2024 fuel meter data, the Porsche Panamera Turbo S E-Hybrid used 11.7 L/100 km (24.1 mpg UK). Its official figure, derived from WLTP CO2, is about 2.7 L/100 km.

Why is the real figure 4.3× the official one?

The official test assumes a high share of electric driving. In real use these cars covered 21% of their distance with the engine off, so the engine ran far more than the test assumes.

Where does this data come from?

From the on-board fuel consumption meters fitted to every new car in the EU since 2021. The European Environment Agency publishes the readings each year under a CC BY 4.0 licence.

Can I get closer to the official figure?

Yes, by charging before most trips and keeping daily journeys within the electric range of about 53 km (official). Use the calculator to see your own likely figure.
