Off the line, the Bmw i4 M50 xDrive hits 100 km/h in 3.92 s versus 7.38 s for the Bmw 120d. The instant torque of 795 Nm from the electric motor makes the difference. At this point, the Bmw i4 M50 xDrive leads by 3.46 s and sits roughly 21 m ahead.
At 200 metres, the Bmw i4 M50 xDrive is doing 155 km/h against 121 km/h for the Bmw 120d. The gap is 2.27 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw i4 M50 xDrive crosses the line in 12.01 s versus 15.41 s. The 3.40 s gap represents roughly 134 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 168 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 27.90 s, with a 5.93 s lead. Both vehicles have similar top speeds (225 vs 231 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw i4 M50 xDrive is capped at 225 km/h, the Bmw 120d at 231 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 11.54 seconds. The 3.46 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, i4 M50 xDrive G26 wins (3,92 s vs 7,38 s).
i4 M50 xDrive G26 goes from 0 to 100 km/h in 3,92 seconds (calibrated simulation).
