Off the line, the Bmw iX3 hits 100 km/h in 6.86 s versus 7.44 s for the Bmw 420i. The instant torque of 400 Nm from the electric motor makes the difference. Despite the faster sprint time, the Bmw 420i is 7 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw 420i is doing 117 km/h against 126 km/h for the Bmw iX3. The gap is 0.04 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw iX3 crosses the line in 15.07 s versus 15.38 s. The 0.31 s gap represents roughly 12 m of track - two to three car lengths.
Past 400 metres, the Bmw iX3 continues to build its lead. At 600 metres, it runs at 172 km/h versus 163 km/h. At 1,000 metres, the Bmw iX3 finishes in 27.54 s versus 28.23 s, with a 0.69 s lead. Despite a higher top speed (238 km/h), the Bmw 420i never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the Bmw iX3 is capped at 180 km/h, the Bmw 420i at 240 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 12.15 seconds. The 0.58 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.
