| Measure | Cayenne S Coupe | 911 Carrera 4 991.2 | Gap |
|---|---|---|---|
| Total time | 7h26 | 7h21 | 5 min · 911 Carrera 4 991.2 |
| Charging stops | 5 stops | 4 stops | 1 stop · 911 Carrera 4 991.2 |
| Cost of energy used | 254.36 € | 141.27 € | 113.09 € · 911 Carrera 4 991.2 |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 4 stops totalling 20 min for the 911 Carrera 4 991.2 versus 5 stops totalling 25 min for the Cayenne S Coupe.
The official WLTP figures (12,1 L/100km for Cayenne S Coupe and 10,2 L/100km for 911 Carrera 4 991.2) 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 15,1 L/100km (Cayenne S Coupe) and 8,4 L/100km (911 Carrera 4 991.2). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 911 Carrera 4 991.2 arrives in 7h21 with 4 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 254.36 € (Cayenne S Coupe) and 141.27 € (911 Carrera 4 991.2). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
