The 5-minute lead of the Model X Long Range does not come from driving speed, but from one fewer charging stop on this route (2 vs 3).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 21 min for the Model X Long Range versus 3 stops totalling 26 min for the G9.

Motorway consumption: the Caralogy methodology

The official WLTP figures (22,6 kWh/100km for Model X Long Range and 20,2 kWh/100km for G9) 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 21,4 kWh/100km (Model X Long Range) and 25,3 kWh/100km (G9). Full methodology: see the assumptions below the controls.

Recovery speed: 18,2 km/min versus 18,5 km/min

During the 21 minutes of charging for the Model X Long Range, range recovers by 383 km. During the 26 cumulative minutes for the G9, range recovers by 480 km. Per minute, both recover at the same rate. The gap is less pronounced but accumulates over long distances.

For reference: how much would an equivalent petrol car cost?

A Peugeot 3008 1.2 PureTech 130 (equivalent segment) consumes about 7,8 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~112 €. That is 1,8× the electric cost of the Model X Long Range and 1,3× that of the G9. The gap narrows in winter but never reverses.

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 Model X Long Range arrives in 7h22 with 2 charging 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 63.38 € (Model X Long Range) and 84.66 € (G9). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
