The 5-minute lead of the M440d xDrive G22 does not come from driving speed, but from one fewer charging stop on this route (0 vs 1).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the M440d xDrive G22 versus 1 stop of 5 min for the Q7 SUV.

Motorway consumption: the Caralogy methodology

The official WLTP figures (5,7 L/100km for M440d xDrive G22 and 8,4 L/100km for Q7 SUV) 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 4,7 L/100km (M440d xDrive G22) and 10,5 L/100km (Q7 SUV). Full methodology: see the assumptions below the controls.

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

On Paris → Marseille (775 km at 130 km/h), the M440d xDrive G22 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 79.04 € (M440d xDrive G22) and 176.58 € (Q7 SUV). For reference, an equivalent Peugeot 508 1.6 PureTech 180 (~7.2 L/100 km) would cost about 103 € in fuel.
