The 35-minute lead of the G 580 with EQ technology W463 does not come from driving speed, but from shorter stops on this route (45 min vs 80 min).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 3 stops totalling 45 min for the G 580 with EQ technology W463 versus 3 stops totalling 80 min for the P7.

Motorway consumption: the Caralogy methodology

The official WLTP figures (24,5 kWh/100km for G 580 with EQ technology W463 and 17,2 kWh/100km for P7) 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 30,6 kWh/100km (G 580 with EQ technology W463) and 20,6 kWh/100km (P7). Full methodology: see the assumptions below the controls.

Recovery speed: 10,3 km/min versus 6,0 km/min

During the 45 minutes of charging for the G 580 with EQ technology W463, range recovers by 464 km. During the 80 cumulative minutes for the P7, range recovers by 479 km. Per minute: the G 580 with EQ technology W463 recovers 1,7× faster. At this rate, the charging stop blends into the trip rhythm - just enough time for a coffee. At a lower rate, it dictates the pace.

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

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 1,1× the electric cost of the G 580 with EQ technology W463 and 1,6× that of the P7. 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 G 580 with EQ technology W463 arrives in 7h46 with 3 charging 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 100.66 € (G 580 with EQ technology W463) and 68.98 € (P7). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
