Cost of energy used

The 27-minute lead of the 540d xDrive Touring G30 (combustion) comes from not needing a charging stop: no stop versus 3 stops totalling 27 min for the P7i (electric).

Both vehicles drove at 130 km/h for the entire trip. The 540d xDrive Touring G30 (combustion) makes no stop, the P7i (electric) 3 stops totalling 27 min. Road safety reminder: on a trip of this duration, it is recommended to stop for at least 51 min total (17 min every 2h). The energy cost is 89,13 € for 540d xDrive Touring G30 versus 65,51 € for P7i.

Motorway consumption: the Caralogy methodology

The official WLTP figures (6,0 L/100km for 540d xDrive Touring G30 and 16,9 kWh/100km for P7i) are measured on a mixed cycle averaging ~46 km/h. At a steady 130 km/h, aerodynamic drag weighs much more heavily - it grows with the square of speed. Caralogy calculates a motorway consumption specific to each vehicle based on its aerodynamic profile (SCx), weight and power curve - not a uniform correction factor. For this trip, the simulation yields 5,3 L/100km (540d xDrive Touring G30) and 20,3 kWh/100km (P7i). Full methodology: see the assumptions below the controls.

What about a 200 km round trip?

On a 200 km round trip (e.g. a weekend getaway), the electric or plug-in hybrid vehicle completes the entire journey on home energy at 0.20 €/kWh - with no charging stop. The time advantage of the combustion car on long-distance motorways disappears entirely, and the economic advantage of electric strengthens considerably.

Energy cost breakdown for your trip Paris → Marseille

The cost per kilometre depends on the electricity rate applied to each segment - based on the energy source used at that point of the trip.

Frequently asked questions

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the 540d xDrive Touring G30 arrives in 7h01 with 0 fuel stops.

WLTP consumption does not reflect motorway reality. Aerodynamic drag grows with the square of speed, so real consumption is 15 to 25 % higher than WLTP combined. Caralogy calculates a highway consumption specific to each vehicle based on its aerodynamic profile (SCx), weight and power curve.

Total time = driving time + charging time. Driving time is calculated at an average speed of 130 km/h on the motorway (adjustable). Charging time is calculated based on the real power curve of each vehicle, respecting the optimal 10 → 80 % range and the maximum power accepted by the chargers on the route.

No. The displayed cost covers only the energy consumed during the trip: kWh × energy rate, with a mix of home charging and DC fast chargers. Battery wear is a long-term ownership cost, not a trip cost.

On this trip, the energy used costs 89.13 € (540d xDrive Touring G30) and 65.51 € (P7i). For reference, an equivalent BMW 530i (~8.0 L/100 km) would cost about 115 € in fuel.
