Trip mapped at a glance. Charging stops visible, total duration predictable. Caralogy simulation at 130 km/h.
| Measure | 718 Cayman GT4 | Panamera S | Gap |
|---|---|---|---|
| Total time | 7h06 | 7h06 | Less than a minute apart |
| Charging stops | 1 stop | 1 stop | Same |
| Cost of energy used | 194.24 € | 236.05 € | 41.81 € · 718 Cayman GT4 |
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 718 Cayman GT4 versus 1 stop of 5 min for the Panamera S.
The official WLTP figures (11,0 L/100km for 718 Cayman GT4 and 12,1 L/100km for Panamera S) 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 11,6 L/100km (718 Cayman GT4) and 14,0 L/100km (Panamera S). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 718 Cayman GT4 arrives in 7h06 with 1 fuel 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.
On this trip, the energy used costs 194.24 € (718 Cayman GT4) and 236.05 € (Panamera S). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
