Off the line, the Bmw X5 M50i hits 100 km/h in 4.34 s versus 6.86 s for the Bmw iX3. Despite lacking instant torque, 530 hp of power compensates. At this point, the Bmw X5 M50i leads by 2.52 s and sits roughly 22 m ahead.
At 200 metres, the Bmw X5 M50i is doing 150 km/h against 126 km/h for the Bmw iX3. The gap is 1.78 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X5 M50i crosses the line in 12.43 s versus 15.07 s. The 2.64 s gap represents roughly 109 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X5 M50i continues to build its lead. At 600 metres, it runs at 209 km/h versus 172 km/h. At 1,000 metres, the Bmw X5 M50i finishes in 22.50 s versus 27.54 s, with a 5.03 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw X5 M50i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw iX3 at 180 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 10.53 seconds. The 2.52 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.
