Both vehicles drive at 130 km/h. The difference comes from charging stops.
Analysis
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 1 stop of 9 min for the CLA 350 4MATIC with EQ technology versus 3 stops totalling 23 min for the Model 3 Performance.
The official WLTP figures (16,5 kWh/100km for Model 3 Performance and 12,2 kWh/100km for CLA 350 4MATIC with EQ technology) 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 19,9 kWh/100km (Model 3 Performance) and 14,6 kWh/100km (CLA 350 4MATIC with EQ technology). Full methodology: see the dedicated button above the summary.
During the 9 minutes of charging for the CLA 350 4MATIC with EQ technology, range recovers by 283 km. During the 23 cumulative minutes for the Model 3 Performance, range recovers by 454 km. Per minute: the CLA 350 4MATIC with EQ technology recovers 1,6× 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.
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 1,6× the electric cost of the Model 3 Performance and 2,7× that of the CLA 350 4MATIC with EQ technology. The gap narrows in winter but never reverses.
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.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the CLA 350 4MATIC with EQ technology arrives in 7h09 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.
Electric: 64,65 € (Model 3 Performance) and 37,48 € (CLA 350 4MATIC with EQ technology). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
