| Measure | 718 Cayman GTS | 430i G22 | Gap |
|---|---|---|---|
| Total time | 7h16 | 7h01 | 15 min · 430i G22 |
| Charging stops | 3 stops | 0 stops | 3 stops · 430i G22 |
| Cost of energy used | 420.44 € | 89.13 € | 331.31 € · 430i G22 |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the 430i G22 versus 3 stops totalling 15 min for the 718 Cayman GTS.
The official WLTP figures (11,2 L/100km for 718 Cayman GTS and 6,1 L/100km for 430i G22) 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 25,0 L/100km (718 Cayman GTS) and 5,3 L/100km (430i G22). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 430i G22 arrives in 7h01 with 0 fuel 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 420.44 € (718 Cayman GTS) and 89.13 € (430i G22). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
