| Measure | Q7 SUV | 420d xDrive F32 | Gap |
|---|---|---|---|
| Total time | 7h06 | 7h01 | 5 min · 420d xDrive F32 |
| Charging stops | 1 stop | 0 stops | 1 stop · 420d xDrive F32 |
| Cost of energy used | 165.44 € | 66.17 € | 99.27 € · 420d xDrive F32 |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the 420d xDrive F32 versus 1 stop of 5 min for the Q7 SUV.
The official WLTP figures (8,4 L/100km for Q7 SUV and 4,6 L/100km for 420d xDrive F32) 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 10,5 L/100km (Q7 SUV) and 4,2 L/100km (420d xDrive F32). Full methodology: see the dedicated button above the summary.

On Paris → Marseille (775 km at 130 km/h), the 420d xDrive F32 arrives in 7h01 with 0 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.
Electric: 165,44 € (Q7 SUV) and 66,17 € (420d xDrive F32). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
