Off the line, the iX xDrive50 hits 100 km/h in 4.69 s versus 6.90 s for the X4 xDrive25d. The instant torque of 765 Nm from the electric motor makes the difference. At this point, the iX xDrive50 leads by 2.22 s and sits roughly 14 m ahead.
At 200 metres, the iX xDrive50 is doing 144 km/h against 121 km/h for the X4 xDrive25d. The gap is 1.30 s. The challenger starts to claw back ground.
At 400 metres standing start, the iX xDrive50 crosses the line in 12.93 s versus 15.07 s. The 2.14 s gap represents roughly 86 m of track - a gap visible to the naked eye.
Past 400 metres, the iX xDrive50 continues to build its lead. At 600 metres, it runs at 200 km/h versus 167 km/h. At 1,000 metres, the iX xDrive50 finishes in 23.92 s versus 27.65 s, with a 3.73 s lead. Despite a higher top speed (228 km/h), the X4 xDrive25d never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the iX xDrive50 is capped at 200 km/h, the X4 xDrive25d at 230 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 11.19 seconds. The 2.22 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, iX xDrive50 I20 wins (4,69 s vs 6,90 s).
iX xDrive50 I20 goes from 0 to 100 km/h in 4,69 seconds (calibrated simulation).
