| Cost of energy used | 68.98 € | 52.19 € | 16.79 € · ID.7 Pro S |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 21 min for the ID.7 Pro S versus 3 stops totalling 80 min for the P7.
The official WLTP figures (17,2 kWh/100km for P7 and 14,9 kWh/100km for ID.7 Pro S) 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 20,6 kWh/100km (P7) and 17,9 kWh/100km (ID.7 Pro S). Full methodology: see the assumptions below the controls.
During the 21 minutes of charging for the ID.7 Pro S, range recovers by 372 km. During the 80 cumulative minutes for the P7, range recovers by 479 km. Per minute: the ID.7 Pro S recovers 3,0× 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 508 1.6 PureTech 180 (equivalent segment) consumes about 7,2 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~103 €. That is 1,5× the electric cost of the P7 and 2,0× that of the ID.7 Pro S. The gap narrows in winter but never reverses.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the ID.7 Pro S arrives in 7h22 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.
On this trip, the energy used costs 68.98 € (P7) and 52.19 € (ID.7 Pro S). For reference, an equivalent Peugeot 508 1.6 PureTech 180 (~7.2 L/100 km) would cost about 103 € in fuel.
