Jeep Grand Cherokee real-world fuel use
How much is really driven with the engine off
For this model the reported engine-off distance does not fit its measured fuel use, so we do not show it. The fuel figure above is unaffected: it comes straight from total fuel and total distance. Because of that, the running-cost calculator is not available for this model.

UK company car tax
Benefit-in-kind tax is based on the official CO2 figure (61 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 Jeep Grand Cherokee really use?
Across 481 cars in the EEA 2024 fuel meter data, the Jeep Grand Cherokee used 10.1 L/100 km (28.1 mpg UK). Its official figure, derived from WLTP CO2, is about 2.6 L/100 km.
Why is the real figure 3.8× the official one?
The official test assumes a high share of electric driving. For this model the reported engine-off distance is not consistent with its fuel use, so we cannot say how much of the gap comes from electric driving. The fuel figure itself comes from total fuel and total distance.
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 48 km (official). Use the calculator to see your own likely figure.
