|---|---|---|---|
| Total time | 7h37 | 7h24 | 13 min · G9 |
| Charging stops | 4 stops | 3 stops | 1 stop · G9 |
| Cost of energy used | 80.88 € | 77.69 € | 3.19 € · G9 |
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 4 stops totalling 36 min for the i4 M50 xDrive G26.
The official WLTP figures (19,7 kWh/100km for i4 M50 xDrive G26 and 19,0 kWh/100km for G9) 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 23,6 kWh/100km (i4 M50 xDrive G26) and 23,8 kWh/100km (G9). Full methodology: see the assumptions below the controls.
During the 23 minutes of charging for the G9, range recovers by 459 km. During the 36 cumulative minutes for the i4 M50 xDrive G26, range recovers by 499 km. Per minute: the G9 recovers 1,4× faster. The gap is less pronounced but accumulates over long distances.
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 1,3× the electric cost of the i4 M50 xDrive G26 and 1,3× that of the G9. 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 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.
On this trip, the energy used costs 80.88 € (i4 M50 xDrive G26) and 77.69 € (G9). For reference, an equivalent Peugeot 508 1.6 PureTech 180 (~7.2 L/100 km) would cost about 103 € in fuel.
