The 46-minute lead of the Dolphin Boost 150kW does not come from driving speed, but from 3 fewer charging stops on this route (3 vs 6).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 3 stops totalling 54 min for the Dolphin Boost 150kW versus 6 stops totalling 100 min for the i3 I01.

Motorway consumption: the Caralogy methodology

The official WLTP figures (14,5 kWh/100km for Dolphin Boost 150kW and 13,1 kWh/100km for i3 I01) 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 15,7 kWh/100km (Dolphin Boost 150kW) and 15,5 kWh/100km (i3 I01). Full methodology: see the assumptions below the controls.

Recovery speed: 8,7 km/min versus 5,8 km/min

During the 54 minutes of charging for the Dolphin Boost 150kW, range recovers by 470 km. During the 100 cumulative minutes for the i3 I01, range recovers by 583 km. Per minute: the Dolphin Boost 150kW recovers 1,5× 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 208 1.2 PureTech 100 (equivalent segment) consumes about 6,2 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~89 €. That is 1,7× the electric cost of the Dolphin Boost 150kW and 1,5× that of the i3 I01. 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 Dolphin Boost 150kW arrives in 7h55 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 51.95 € (Dolphin Boost 150kW) and 58.24 € (i3 I01). For reference, an equivalent Peugeot 208 1.2 PureTech 100 (~6.2 L/100 km) would cost about 89 € in fuel.
