Analysis

The 5-minute lead of the 840d xDrive G15 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 840d xDrive G15 versus 1 stop of 5 min for the A8 L 55 TFSI quattro tiptronic 250 kW MHEV.

Motorway consumption: the Caralogy methodology

The official WLTP figures (10,4 L/100km for A8 L 55 TFSI quattro tiptronic 250 kW MHEV and 5,8 L/100km for 840d xDrive G15) 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 12,1 L/100km (A8 L 55 TFSI quattro tiptronic 250 kW MHEV) and 5,0 L/100km (840d xDrive G15). 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 840d xDrive G15 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: 186,06 € (A8 L 55 TFSI quattro tiptronic 250 kW MHEV) and 77,11 € (840d xDrive G15). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
