Off the line, the Bmw X4 M40i hits 100 km/h in 4.76 s versus 4.93 s for the Q8 SUV. Despite lacking instant torque, 354 hp of power compensates. At this point, the Bmw X4 M40i leads by 0.17 s and sits roughly 1 m ahead.
At 200 metres, the Bmw X4 M40i is doing 143 km/h against 140 km/h for the Q8 SUV. The gap is 0.12 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 195 km/h. At 1,000 metres, the Bmw X4 M40i finishes in 23.60 s versus 23.96 s, with a 0.36 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Q8 SUV is capped at 240 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 7.54 seconds. The 0.17 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.
