Off the line, the Bmw X4 M40i hits 100 km/h in 4.76 s versus 4.84 s for the I-PACE EV400. Despite lacking instant torque, 354 hp of power compensates. The 0.08 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw X4 M40i is doing 143 km/h against 141 km/h for the I-PACE EV400. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw X4 M40i crosses the line in 12.99 s versus 13.18 s. The 0.19 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the Bmw X4 M40i continues to build its lead. At 600 metres, it runs at 198 km/h versus 192 km/h. At 1,000 metres, the Bmw X4 M40i finishes in 23.60 s versus 24.36 s, with a 0.76 s lead.
Both rivals are electronically governed, but not at the same level: the I-PACE EV400 is capped at 200 km/h, the Bmw X4 M40i 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 7.37 seconds. The 0.08 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.
