Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 19 min for the Model Y Long Range AWD versus 3 stops totalling 50 min for the i7 M70 xDrive G70.
The official WLTP figures (22,5 kWh/100km for i7 M70 xDrive G70 and 16,9 kWh/100km for Model Y Long Range AWD) 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 26,1 kWh/100km (i7 M70 xDrive G70) and 18,1 kWh/100km (Model Y Long Range AWD). Full methodology: see the assumptions below the controls.
During the 19 minutes of charging for the Model Y Long Range AWD, range recovers by 395 km. During the 50 cumulative minutes for the i7 M70 xDrive G70, range recovers by 454 km. Per minute: the Model Y Long Range AWD recovers 2,3× faster. At this rate, the charging stop blends into the trip rhythm - just enough time for a coffee. At a lower rate, it dictates the pace.
A Mercedes S 450 (equivalent segment) consumes about 9,0 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~129 €. That is 1,5× the electric cost of the i7 M70 xDrive G70 and 2,4× that of the Model Y Long Range AWD. The gap narrows in winter but never reverses.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the Model Y Long Range AWD arrives in 7h19 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 84.76 € (i7 M70 xDrive G70) and 54.42 € (Model Y Long Range AWD). For reference, an equivalent Mercedes S 450 (~9.0 L/100 km) would cost about 129 € in fuel.
