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 26 min for the G9.
The official WLTP figures (20,2 kWh/100km for G9 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 25,3 kWh/100km (G9) and 14,6 kWh/100km (CLA 350 4MATIC with EQ technology). Full methodology: see the assumptions below the controls.
During the 9 minutes of charging for the CLA 350 4MATIC with EQ technology, range recovers by 283 km. During the 26 cumulative minutes for the G9, range recovers by 480 km. Per minute: the CLA 350 4MATIC with EQ technology 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.
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 1,3× the electric cost of the G9 and 3,0× that of the CLA 350 4MATIC with EQ technology. The gap narrows in winter but never reverses.

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.
On this trip, the energy used costs 84.66 € (G9) and 37.48 € (CLA 350 4MATIC with EQ technology). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
