The 9-minute lead of the iX xDrive50 I20 does not come from driving speed, but from shorter stops on this route (35 min vs 44 min).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 35 min for the iX xDrive50 I20 versus 2 stops totalling 44 min for the Model X 100D.

Motorway consumption: the Caralogy methodology

The official WLTP figures (22,5 kWh/100km for Model X 100D and 21,1 kWh/100km for iX xDrive50 I20) 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 23,0 kWh/100km (Model X 100D) and 24,5 kWh/100km (iX xDrive50 I20). Full methodology: see the assumptions below the controls.

Recovery speed: 12,0 km/min versus 9,4 km/min

During the 35 minutes of charging for the iX xDrive50 I20, range recovers by 419 km. During the 44 cumulative minutes for the Model X 100D, range recovers by 414 km. Per minute: the iX xDrive50 I20 recovers 1,3× faster. 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 1,6× the electric cost of the Model X 100D and 1,5× that of the iX xDrive50 I20. 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 iX xDrive50 I20 arrives in 7h36 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 71.01 € (Model X 100D) and 76.06 € (iX xDrive50 I20). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
