Off the line, the X4 M40d hits 100 km/h in 4.81 s versus 6.04 s for the iX xDrive40. Despite lacking instant torque, 340 hp of power compensates. At this point, the X4 M40d leads by 1.23 s and sits roughly 11 m ahead.
At 200 metres, the X4 M40d is doing 139 km/h against 127 km/h for the iX xDrive40. The gap is 0.79 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.13 s versus 14.36 s. The 1.24 s gap represents roughly 53 m of track - a gap visible to the naked eye.
Past 400 metres, the X4 M40d continues to build its lead. At 600 metres, it runs at 193 km/h versus 175 km/h. At 1,000 metres, the X4 M40d finishes in 24.04 s versus 26.37 s, with a 2.33 s lead.
Both rivals are electronically governed, but not at the same level: the X4 M40d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the iX xDrive40 at 200 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 9.74 seconds. The 1.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X4 M40d G02 wins (4,81 s vs 6,04 s).
