The 29-minute lead of the S6 Sportback e-tron does not come from driving speed, but from 2 fewer charging stops on this route (2 vs 4).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 32 min for the S6 Sportback e-tron versus 4 stops totalling 61 min for the Model S P85D.

Motorway consumption: the Caralogy methodology

The official WLTP figures (22,5 kWh/100km for Model S P85D and 16,5 kWh/100km for S6 Sportback 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 23,0 kWh/100km (Model S P85D) and 19,5 kWh/100km (S6 Sportback e-tron). Full methodology: see the assumptions below the controls.

Recovery speed: 11,5 km/min versus 8,2 km/min

During the 32 minutes of charging for the S6 Sportback e-tron, range recovers by 368 km. During the 61 cumulative minutes for the Model S P85D, range recovers by 502 km. Per minute: the S6 Sportback e-tron recovers 1,4× faster. The gap is less pronounced but accumulates over long distances.

For reference: how much would an equivalent petrol car cost?

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 1,5× the electric cost of the Model S P85D and 2,0× that of the S6 Sportback e-tron. 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 S6 Sportback e-tron arrives in 7h33 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 79.10 € (Model S P85D) and 56.56 € (S6 Sportback e-tron). For reference, an equivalent BMW 530i (~8.0 L/100 km) would cost about 115 € in fuel.
