| Measure | X7 xDrive50i G07 | 318d G20 | Gap |
|---|---|---|---|
| Total time | 7h06 | 7h01 | 5 min · 318d G20 |
| Charging stops | 1 stop | 0 stops | 1 stop · 318d G20 |
| Cost of energy used | 224.52 € | 64.60 € | 159.92 € · 318d G20 |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the 318d G20 versus 1 stop of 5 min for the X7 xDrive50i G07.
The official WLTP figures (11,4 L/100km for X7 xDrive50i G07 and 4,6 L/100km for 318d G20) 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 14,3 L/100km (X7 xDrive50i G07) and 4,1 L/100km (318d G20). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 318d G20 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: 224,52 € (X7 xDrive50i G07) and 64,60 € (318d G20). An equivalent Peugeot 3008 1.2 PureTech 130 (~7,8 L/100 km) would cost about 112 € in motorway fuel. Electric costs less in energy but adds charging stops.
