The 31-minute lead of the 520e G30 does not come from driving speed, but from one fewer charging stop on this route (1 vs 2).

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 520e G30 versus 2 stops totalling 36 min for the Seal 313 2WD.

Motorway consumption: the Caralogy methodology

The official WLTP figures (16,0 kWh/100km for Seal 313 2WD and 21,5 kWh/100km for 520e G30) 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 17,3 kWh/100km (Seal 313 2WD) and 10,0 L/100km (520e G30). Full methodology: see the assumptions below the controls.

For reference: how much would an equivalent petrol car cost?

A Peugeot 508 1.6 PureTech 180 (equivalent segment) consumes about 7,2 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~103 €. That is 2,0× the electric cost of the Seal 313 2WD and 0,6× that of the 520e G30. The gap narrows in winter but never reverses.

Energy cost breakdown for your trip Paris → Marseille

The cost per kilometre depends on the electricity rate applied to each segment - based on the energy source used at that point of the trip.

Frequently asked questions

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the 520e G30 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 51.65 € (Seal 313 2WD) and 158.49 € (520e G30). For reference, an equivalent Peugeot 508 1.6 PureTech 180 (~7.2 L/100 km) would cost about 103 € in fuel.
