Off the line, the Bmw X4 xDrive25d hits 100 km/h in 6.90 s versus 6.93 s for the Q8 SUV. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Q8 SUV is doing 119 km/h against 121 km/h for the Bmw X4 xDrive25d. The gap is 0.13 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Q8 SUV crosses the line in 15.03 s versus 15.07 s. The 0.03 s gap represents roughly 1 m of track
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.12 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.
Both rivals are electronically governed, but not at the same level: the Q8 SUV is capped at 226 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (9.35 kg/hp vs 7.60 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.52 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Q8 SUV and X4 xDrive25d G02 are neck and neck (6,90 s vs 6,93 s, no significant gap).
Q8 SUV goes from 0 to 100 km/h in 6,93 seconds (calibrated simulation).
