Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 1 stop of 5 min for the 320e G20 versus 2 stops totalling 32 min for the S6 Sportback e-tron.
The official WLTP figures (16,5 kWh/100km for S6 Sportback e-tron and 14,8 kWh/100km for 320e G20) 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 19,5 kWh/100km (S6 Sportback e-tron) and 9,6 L/100km (320e G20). Full methodology: see the assumptions below the controls.
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 2,0× the electric cost of the S6 Sportback e-tron and 0,8× that of the 320e G20. 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 320e G20 arrives in 7h06 with 1 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 56.56 € (S6 Sportback e-tron) and 152.16 € (320e G20). For reference, an equivalent BMW 530i (~8.0 L/100 km) would cost about 115 € in fuel.
