Off the line, the i4 M50 xDrive hits 100 km/h in 3.92 s versus 7.12 s for the 120i. The instant torque of 795 Nm from the electric motor makes the difference. At this point, the i4 M50 xDrive leads by 3.20 s and sits roughly 20 m ahead.
At 200 metres, the i4 M50 xDrive is doing 155 km/h against 122 km/h for the 120i. The gap is 2.13 s. The challenger starts to claw back ground.
At 400 metres standing start, the i4 M50 xDrive crosses the line in 12.01 s versus 15.22 s. The 3.21 s gap represents roughly 129 m of track - a gap visible to the naked eye.
Past 400 metres, the i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 170 km/h. At 1,000 metres, the i4 M50 xDrive finishes in 21.97 s versus 27.52 s, with a 5.56 s lead. Both vehicles have similar top speeds (225 vs 225 km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the i4 M50 xDrive and the 120i are governed to 225 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
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 11.27 seconds. The 3.20 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 7,12 s).
i4 M50 xDrive G26 goes from 0 to 100 km/h in 3,92 seconds (calibrated simulation).
