Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 1 stop of 14 min for the A6 Avant e-tron versus 2 stops totalling 34 min for the Model S P100D.
The official WLTP figures (20,5 kWh/100km for Model S P100D and 14,8 kWh/100km for A6 Avant e-tron) 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 20,7 kWh/100km (Model S P100D) and 17,5 kWh/100km (A6 Avant e-tron). Full methodology: see the assumptions below the controls.
During the 14 minutes of charging for the A6 Avant e-tron, range recovers by 315 km. During the 34 cumulative minutes for the Model S P100D, range recovers by 380 km. Per minute: the A6 Avant e-tron recovers 2,0× 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 BMW 530i (equivalent segment) consumes about 8,0 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~115 €. That is 1,9× the electric cost of the Model S P100D and 2,4× that of the A6 Avant e-tron. 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 A6 Avant e-tron arrives in 7h15 with 1 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.
On this trip, the energy used costs 61.12 € (Model S P100D) and 47.05 € (A6 Avant e-tron). For reference, an equivalent BMW 530i (~8.0 L/100 km) would cost about 115 € in fuel.
