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: 2 stops totalling 25 min for the G6 versus 4 stops totalling 52 min for the ID.4 GTX.
The official WLTP figures (17,9 kWh/100km for ID.4 GTX and 15,4 kWh/100km for G6) 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 22,4 kWh/100km (ID.4 GTX) and 19,3 kWh/100km (G6). Full methodology: see the dedicated button above the summary.
During the 25 minutes of charging for the G6, range recovers by 421 km. During the 52 cumulative minutes for the ID.4 GTX, range recovers by 495 km. Per minute: the G6 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 1,8× the electric cost of the ID.4 GTX and 2,3× that of the G6. 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 G6 arrives in 7h26 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.
Electric: 61,40 € (ID.4 GTX) and 49,42 € (G6). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
