| Cost of energy used | 59.47 € | 47.05 € | 12.42 € · A6 Avant e-tron |
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 19 min for the Model S Performance.
The official WLTP figures (19,3 kWh/100km for Model S Performance 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 20,5 kWh/100km (Model S Performance) 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 19 cumulative minutes for the Model S Performance, range recovers by 367 km. Per minute: the A6 Avant e-tron recovers 1,2× faster. The gap is less pronounced but accumulates over long distances.
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 Performance 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.
Electric: 59,47 € (Model S Performance) and 47,05 € (A6 Avant e-tron). An equivalent BMW 530i (~8,0 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
