Off the line, the Bmw i5 xDrive40 hits 100 km/h in 5.30 s versus 6.48 s for the Bmw 125d. The instant torque of 590 Nm from the electric motor makes the difference. At this point, the Bmw i5 xDrive40 leads by 1.18 s and sits roughly 15 m ahead.
At 200 metres, the Bmw i5 xDrive40 is doing 137 km/h against 130 km/h for the Bmw 125d. The gap is 0.82 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw i5 xDrive40 crosses the line in 13.59 s versus 14.67 s. The 1.09 s gap represents roughly 48 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw i5 xDrive40 continues to build its lead. At 600 metres, it runs at 191 km/h versus 180 km/h. At 1,000 metres, the Bmw i5 xDrive40 finishes in 24.58 s versus 26.39 s, with a 1.82 s lead. Despite a higher top speed (240 km/h), the Bmw 125d never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the Bmw i5 xDrive40 is capped at 215 km/h, the Bmw 125d at 240 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 9.81 seconds. The 1.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
