Analysis

The 5-minute lead of the 640i xDrive Gran Turismo G32 does not come from driving speed, but from one fewer charging stop on this route (0 vs 1).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the 640i xDrive Gran Turismo G32 versus 1 stop of 5 min for the A6 Sedan TFSI quattro S tronic 270 kW.

Motorway consumption: the Caralogy methodology

The official WLTP figures (8,1 L/100km for A6 Sedan TFSI quattro S tronic 270 kW and 8,2 L/100km for 640i xDrive Gran Turismo G32) 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 9,6 L/100km (A6 Sedan TFSI quattro S tronic 270 kW) and 6,7 L/100km (640i xDrive Gran Turismo G32). Full methodology: see the dedicated button above the summary.

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

On Paris → Marseille (775 km at 130 km/h), the 640i xDrive Gran Turismo G32 arrives in 7h01 with 0 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: 147,41 € (A6 Sedan TFSI quattro S tronic 270 kW) and 103,33 € (640i xDrive Gran Turismo G32). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
