190 ch · 2020
Trip mapped at a glance. Charging stops visible, total duration predictable. Caralogy simulation at 130 km/h.
| Measure | 120d F40 | A3 Sedan | Gap |
|---|---|---|---|
| Total time | 7h01 | 7h01 | Less than a minute apart |
| Charging stops | 0 stops | 0 stops | Same |
| Cost of energy used | 66.17 € | 80.35 € | 14.18 € · 120d F40 |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the 120d F40 versus no stop for the A3 Sedan.
The official WLTP figures (4,6 L/100km for 120d F40 and 5,5 L/100km for A3 Sedan) 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 4,2 L/100km (120d F40) and 5,1 L/100km (A3 Sedan). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 120d F40 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: 66,17 € (120d F40) and 80,35 € (A3 Sedan). An equivalent Peugeot 308 1.2 PureTech 130 (~6,8 L/100 km) would cost about 97 € in motorway fuel. Electric costs less in energy but adds charging stops.
