Analysis

The 22-minute lead of the 320d xDrive G20 (combustion) comes from not needing a charging stop: no stop versus 3 stops totalling 22 min for the Model 3 Performance (electric).

Both vehicles drove at 130 km/h for the entire trip. The 320d xDrive G20 (combustion) makes no stop, the Model 3 Performance (electric) 3 stops totalling 22 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 50,77 € for Model 3 Performance versus 67,86 € for 320d xDrive G20.

Motorway consumption: the Caralogy methodology

The official WLTP figures (16,7 kWh/100km for Model 3 Performance and 4,8 L/100km for 320d xDrive G20) 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 19,4 kWh/100km (Model 3 Performance) and 4,4 L/100km (320d xDrive G20). Full methodology: see the dedicated button above the summary.

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 0.18 €/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 320d xDrive G20 arrives in 7h01 with 0 charging 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: 50,77 € (Model 3 Performance) and 67,86 € (320d xDrive G20). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
