The 10-minute lead of the GLC 400 4MATIC X254 does not come from driving speed, but from 2 fewer charging stops on this route (1 vs 3).

Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 1 stop of 10 min for the GLC 400 4MATIC X254 versus 3 stops totalling 20 min for the Model Y Long Range AWD.

Motorway consumption: the Caralogy methodology

The official WLTP figures (13,2 kWh/100km for GLC 400 4MATIC X254 and 16,9 kWh/100km for Model Y Long Range AWD) 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 16,5 kWh/100km (GLC 400 4MATIC X254) and 18,2 kWh/100km (Model Y Long Range AWD). Full methodology: see the assumptions below the controls.

Recovery speed: 29,2 km/min versus 21,8 km/min

During the 10 minutes of charging for the GLC 400 4MATIC X254, range recovers by 292 km. During the 20 cumulative minutes for the Model Y Long Range AWD, range recovers by 435 km. Per minute: the GLC 400 4MATIC X254 recovers 1,3× faster. The gap is less pronounced but accumulates over long distances.

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 2,6× the electric cost of the GLC 400 4MATIC X254 and 1,9× that of the Model Y Long Range AWD. 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 GLC 400 4MATIC X254 arrives in 7h11 with 1 charging 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 42.89 € (GLC 400 4MATIC X254) and 57.68 € (Model Y Long Range AWD). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
