Analysis

Very close result: less than one minute apart on this route. Both vehicles are evenly matched on the motorway over this distance.

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the X3 xDrive30d G01 versus no stop for the 120d F20LCI.

Motorway consumption: the Caralogy methodology

The official WLTP figures (5,6 L/100km for X3 xDrive30d G01 and 4,7 L/100km for 120d F20LCI) 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 5,0 L/100km (X3 xDrive30d G01) and 4,3 L/100km (120d F20LCI). Full methodology: see the dedicated button above the summary.

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 X3 xDrive30d G01 arrives in 7h01 with 0 stop.

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.

Electric: 77,11 € (X3 xDrive30d G01) and 66,32 € (120d F20LCI). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
