Off the line, the Bmw 540i xDrive hits 100 km/h in 4.96 s versus 6.86 s for the Bmw iX3. Despite lacking instant torque, 333 hp of power compensates. At this point, the Bmw 540i xDrive leads by 1.90 s and sits roughly 21 m ahead.
At 200 metres, the Bmw 540i xDrive is doing 141 km/h against 126 km/h for the Bmw iX3. The gap is 1.32 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 540i xDrive crosses the line in 13.16 s versus 15.07 s. The 1.91 s gap represents roughly 80 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 540i xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 172 km/h. At 1,000 metres, the Bmw 540i xDrive finishes in 23.73 s versus 27.54 s, with a 3.81 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 540i xDrive 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 1.90 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 540i xDrive G30 wins (4,96 s vs 6,86 s).
540i xDrive G30 goes from 0 to 100 km/h in 4,96 seconds (calibrated simulation).
