Trip mapped at a glance. Charging stops visible, total duration predictable. Caralogy simulation at 130 km/h.
| Measure | Cayenne Turbo Coupe | G9 | Gap |
|---|---|---|---|
| Total time | 7h31 | 7h24 | 7 min · G9 |
| Charging stops | 6 stops | 3 stops | 3 stops · G9 |
| Cost of energy used | 288.00 € | 77.69 € | 210.31 € · G9 |
Both vehicles drove at 130 km/h for the entire trip. The G9 (electric) makes 3 stops totalling 23 min, the Cayenne Turbo Coupe (combustion) 6 stops totalling 30 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 288,00 € for Cayenne Turbo Coupe versus 77,69 € for G9.
The official WLTP figures (13,7 L/100km for Cayenne Turbo Coupe and 19,0 kWh/100km for G9) 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 17,1 L/100km (Cayenne Turbo Coupe) and 23,8 kWh/100km (G9). 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.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the G9 arrives in 7h24 with 3 charging 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 288.00 € (Cayenne Turbo Coupe) and 77.69 € (G9). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
