Trip mapped at a glance. Charging stops visible, total duration predictable. Caralogy simulation at 130 km/h.
| Measure | 420d G22 | A3 Sportback | Gap |
|---|---|---|---|
| Total time | 7h01 | 7h06 | 5 min · 420d G22 |
| Charging stops | 0 stops | 1 stop | 1 stop · 420d G22 |
| Cost of energy used | 65.59 € | 106.96 € | 41.37 € · 420d G22 |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the 420d G22 versus 1 stop of 5 min for the A3 Sportback.
The official WLTP figures (4,2 L/100km for 420d G22 and 5,3 L/100km for A3 Sportback) 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 3,9 L/100km (420d G22) and 6,4 L/100km (A3 Sportback). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 420d G22 arrives in 7h01 with 0 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 65.59 € (420d G22) and 106.96 € (A3 Sportback). For reference, an equivalent Peugeot 508 1.6 PureTech 180 (~7.2 L/100 km) would cost about 103 € in fuel.
