Off the line, the Bmw i5 eDrive40 hits 100 km/h in 6.12 s versus 6.15 s for the Bmw 125i. The instant torque of 400 Nm from the electric motor makes the difference. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 125i is doing 131 km/h against 135 km/h for the Bmw i5 eDrive40. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw i5 eDrive40 crosses the line in 14.29 s versus 14.35 s. The 0.06 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the Bmw i5 eDrive40 continues to build its lead. At 600 metres, it runs at 186 km/h versus 182 km/h. At 1,000 metres, the Bmw i5 eDrive40 finishes in 25.87 s versus 25.91 s, with a 0.04 s lead. Despite a higher top speed (243 km/h), the Bmw 125i never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the Bmw i5 eDrive40 is capped at 193 km/h, the Bmw 125i at 243 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.35 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, i5 eDrive40 G60 and 125i F20LCI are neck and neck (6,12 s vs 6,15 s, no significant gap).
i5 eDrive40 G60 goes from 0 to 100 km/h in 6,12 seconds (calibrated simulation).
