Trip mapped at a glance. Charging stops visible, total duration predictable. Caralogy simulation at 130 km/h.
| Measure | Cayenne E-Hybrid | Q7 SUV | Gap |
|---|---|---|---|
| Total time | 7h31 | 7h06 | 25 min · Q7 SUV |
| Charging stops | 6 stops | 1 stop | 5 stops · Q7 SUV |
| Cost of energy used | 247.22 € | 195.63 € | 51.59 € · Q7 SUV |
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 Q7 SUV versus 6 stops totalling 30 min for the Cayenne E-Hybrid.
The official WLTP figures (11,8 L/100km for Cayenne E-Hybrid and 28,6 kWh/100km for Q7 SUV) 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 14,7 L/100km (Cayenne E-Hybrid) and 12,6 L/100km (Q7 SUV). Full methodology: see the assumptions below the controls.
A Peugeot 3008 1.2 PureTech 130 (equivalent segment) consumes about 7,8 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~112 €. That is 0,5× the electric cost of the Cayenne E-Hybrid and 0,6× that of the Q7 SUV. The gap narrows in winter but never reverses.

On Paris → Marseille (775 km at 130 km/h), the Q7 SUV arrives in 7h06 with 1 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 247.22 € (Cayenne E-Hybrid) and 195.63 € (Q7 SUV). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
