The 22-minute lead of the 545e xDrive G30 does not come from driving speed, but from shorter stops on this route (10 min vs 32 min).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 10 min for the 545e xDrive G30 versus 2 stops totalling 32 min for the S6 Sportback e-tron.

Motorway consumption: the Caralogy methodology

The official WLTP figures (16,5 kWh/100km for S6 Sportback e-tron and 22,9 kWh/100km for 545e xDrive G30) 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 11,8 L/100km (545e xDrive G30). Full methodology: see the assumptions below the controls.

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 2,0× the electric cost of the S6 Sportback e-tron and 0,6× that of the 545e xDrive G30. 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 545e xDrive G30 arrives in 7h11 with 2 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 56.56 € (S6 Sportback e-tron) and 188.14 € (545e xDrive G30). For reference, an equivalent BMW 530i (~8.0 L/100 km) would cost about 115 € in fuel.
