Off the line, the i4 M50 xDrive hits 100 km/h in 3.92 s versus 4.69 s for the M4 Convertible. The instant torque of 795 Nm from the electric motor makes the difference. At this point, the i4 M50 xDrive leads by 0.77 s and sits roughly 9 m ahead.
At 200 metres, the i4 M50 xDrive is doing 155 km/h against 151 km/h for the M4 Convertible. The gap is 0.57 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 12.64 s. The 0.64 s gap represents roughly 33 m of track - a gap visible to the naked eye.
Past 400 metres, the gap narrows. The i4 M50 xDrive maxes out at 225 km/h while the M4 Convertible keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.68 s.
At 1,000 metres, the i4 M50 xDrive finishes in 21.97 s versus 22.51 s, with just 0.55 s to spare. The M4 Convertible fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the i4 M50 xDrive is capped at 225 km/h, the M4 Convertible at 250 (i.e. 155 mph - industry threshold) 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 6.66 seconds. The 0.77 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 4,69 s).
i4 M50 xDrive G26 goes from 0 to 100 km/h in 3,92 seconds (calibrated simulation).
