Trip mapped at a glance. Charging stops visible, total duration predictable. Caralogy simulation at 130 km/h.
| Measure | M4 Coupe F82 | M140i xDrive F20LCI | Gap |
|---|---|---|---|
| Total time | 7h06 | 7h06 | Less than a minute apart |
| Charging stops | 1 stop | 1 stop | Same |
| Cost of energy used | 132.35 € | 107.14 € | 25.21 € · M140i xDrive F20LCI |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 1 stop of 5 min for the M4 Coupe F82 versus 1 stop of 5 min for the M140i xDrive F20LCI.
The official WLTP figures (10,0 L/100km for M4 Coupe F82 and 8,0 L/100km for M140i xDrive F20LCI) 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 8,4 L/100km (M4 Coupe F82) and 6,8 L/100km (M140i xDrive F20LCI). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the M4 Coupe F82 arrives in 7h06 with 1 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: 132,35 € (M4 Coupe F82) and 107,14 € (M140i xDrive F20LCI). An equivalent Peugeot 508 1.6 PureTech 180 (~7,2 L/100 km) would cost about 103 € in motorway fuel. Electric costs less in energy but adds charging stops.
