| Total time | 7h01 | 7h06 | 5 min · M340i xDrive G20 |
| Charging stops | 0 stops | 1 stop | 1 stop · M340i xDrive G20 |
| Cost of energy used | 102.59 € | 172.81 € | 70.22 € · M340i xDrive G20 |
Both vehicles drove at 130 km/h for the entire trip. The M340i xDrive G20 (combustion) makes no stop, the 740Le iPerformance G11 (plug-in hybrid) 1 stop of 5 min. Road safety reminder: on a trip of this duration, it is recommended to stop for at least 51 min total (17 min every 2h). The energy cost is 102,59 € for M340i xDrive G20 versus 172,81 € for 740Le iPerformance G11.
The official WLTP figures (7,4 L/100km for M340i xDrive G20 and 21,0 kWh/100km for 740Le iPerformance G11) 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 6,1 L/100km (M340i xDrive G20) and 10,7 L/100km (740Le iPerformance G11). Full methodology: see the assumptions below the controls.
On a 200 km round trip (e.g. a weekend getaway), the electric or plug-in hybrid vehicle completes the entire journey on home energy at 0.20 €/kWh - with no charging stop. The time advantage of the combustion car on long-distance motorways disappears entirely, and the economic advantage of electric strengthens considerably.

On Paris → Marseille (775 km at 130 km/h), the M340i xDrive G20 arrives in 7h01 with 0 fuel 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 102.59 € (M340i xDrive G20) and 172.81 € (740Le iPerformance G11). For reference, an equivalent Peugeot 508 1.6 PureTech 180 (~7.2 L/100 km) would cost about 103 € in fuel.
