| Total time | 7h06 | 7h01 | 5 min · 320d G20 |
| Charging stops | 1 stop | 0 stops | 1 stop · 320d G20 |

Both vehicles drove at 130 km/h for the entire trip. The 320d G20 (hybrid) makes no stop, the S 580 e 4MATIC W223 (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 159,29 € for S 580 e 4MATIC W223 versus 63,91 € for 320d G20.
The official WLTP figures (25,7 kWh/100km for S 580 e 4MATIC W223 and 4,1 L/100km for 320d 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 10,4 L/100km (S 580 e 4MATIC W223) and 3,8 L/100km (320d G20). 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 320d 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 159.29 € (S 580 e 4MATIC W223) and 63.91 € (320d G20). For reference, an equivalent Mercedes S 450 (~9.0 L/100 km) would cost about 129 € in fuel.
