Both vehicles drive at 130 km/h. The difference comes from charging stops.
Analysis
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 3 stops totalling 23 min for the G9 versus 2 stops totalling 36 min for the Q4 45 e-tron 210 kW.
The official WLTP figures (19,0 kWh/100km for G9 and 14,1 kWh/100km for Q4 45 e-tron 210 kW) 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 23,8 kWh/100km (G9) and 17,6 kWh/100km (Q4 45 e-tron 210 kW). Full methodology: see the dedicated button above the summary.
During the 23 minutes of charging for the G9, range recovers by 459 km. During the 36 cumulative minutes for the Q4 45 e-tron 210 kW, range recovers by 412 km. Per minute: the G9 recovers 1,8× faster. At this rate, the charging stop blends into the trip rhythm - just enough time for a coffee. At a lower rate, it dictates the pace.
A Peugeot 3008 1.2 PureTech 130 (equivalent segment) consumes about 7,8 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~112 €. That is 1,4× the electric cost of the G9 and 2,1× that of the Q4 45 e-tron 210 kW. The gap narrows in winter but never reverses.
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.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the G9 arrives in 7h24 with 3 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.
Electric: 77,69 € (G9) and 54,24 € (Q4 45 e-tron 210 kW). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
