Off the line, the Bmw X4 xDrive25d hits 100 km/h in 6.90 s versus 8.51 s for the G9. Despite lacking instant torque, 231 hp of power compensates. At this point, the Bmw X4 xDrive25d leads by 1.61 s and sits roughly 29 m ahead.
At 200 metres, the Bmw X4 xDrive25d is doing 121 km/h against 120 km/h for the G9. The gap is 1.22 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X4 xDrive25d crosses the line in 15.07 s versus 16.32 s. The 1.25 s gap represents roughly 51 m of track - a gap visible to the naked eye.
Past 400 metres, the gap narrows. The G9 maxes out at 200 km/h while the Bmw X4 xDrive25d keeps accelerating towards 228 km/h. At 600 metres, the gap has dropped to 1.22 s.
At 1,000 metres, the Bmw X4 xDrive25d finishes in 27.65 s versus 28.71 s, with just 1.06 s to spare. The G9 fails to fully close the launch gap.
The Bmw X4 xDrive25d 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 G9 is capped at 200 km/h, the Bmw X4 xDrive25d at 230 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 1.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X4 xDrive25d G02 wins (6,90 s vs 8,51 s).
G9 goes from 0 to 100 km/h in 8,51 seconds (calibrated simulation).
