Off the line, the Bmw X4 M40i hits 100 km/h in 4.76 s versus 8.51 s for the G9. Despite lacking instant torque, 354 hp of power compensates. At this point, the Bmw X4 M40i leads by 3.76 s and sits roughly 33 m ahead.
At 200 metres, the Bmw X4 M40i is doing 143 km/h against 120 km/h for the G9. The gap is 2.49 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X4 M40i crosses the line in 12.99 s versus 16.32 s. The 3.33 s gap represents roughly 131 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X4 M40i continues to build its lead. At 600 metres, it runs at 198 km/h versus 169 km/h. At 1,000 metres, the Bmw X4 M40i finishes in 23.60 s versus 28.71 s, with a 5.11 s lead.
The Bmw X4 M40i features all-wheel drive (AWD) against the G9’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Bmw X4 M40i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the G9 at 200 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 12.63 seconds. The 3.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
