Off the line, the iX xDrive50 hits 100 km/h in 4.69 s versus 4.81 s for the Bmw X4 M40d. The instant torque of 765 Nm from the electric motor makes the difference. Despite the faster sprint time, the Bmw X4 M40d is 3 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the iX xDrive50 is doing 144 km/h against 138 km/h for the Bmw X4 M40d. The gap is 0.04 s. The gap remains stable from the start.
At 400 metres standing start, the iX xDrive50 crosses the line in 12.93 s versus 13.14 s. The 0.22 s gap represents roughly 10 m of track - two to three car lengths.
Past 400 metres, the iX xDrive50 continues to build its lead. At 600 metres, it runs at 200 km/h versus 192 km/h. At 1,000 metres, the iX xDrive50 finishes in 23.92 s versus 24.09 s, with a 0.17 s lead. Despite a higher top speed (250 (i.e. 155 mph - industry threshold) km/h), the Bmw X4 M40d 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 Bmw X4 M40d 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 7.57 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
