| Measure | Z4 sDrive30i G29 | 125d F20LCI | Gap |
|---|---|---|---|
| Total time | 7h01 | 7h01 | Less than a minute apart |
| Charging stops | 0 stops | 0 stops | Same |
| Cost of energy used | 89.13 € | 72.32 € | 16.81 € · 125d F20LCI |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the Z4 sDrive30i G29 versus no stop for the 125d F20LCI.
The official WLTP figures (6,0 L/100km for Z4 sDrive30i G29 and 4,8 L/100km for 125d F20LCI) 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 5,3 L/100km (Z4 sDrive30i G29) and 4,3 L/100km (125d F20LCI). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the Z4 sDrive30i G29 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 89.13 € (Z4 sDrive30i G29) and 72.32 € (125d F20LCI). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
