Off the line, the X4 xDrive25d hits 100 km/h in 6.90 s versus 8.50 s for the X4 xDrive20i. At this point, the X4 xDrive25d leads by 1.60 s and sits roughly 12 m ahead.
At 200 metres, the X4 xDrive25d is doing 121 km/h against 112 km/h for the X4 xDrive20i. The gap is 0.72 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 xDrive25d crosses the line in 15.07 s versus 16.22 s. The 1.15 s gap represents roughly 44 m of track - a gap visible to the naked eye.
Past 400 metres, the X4 xDrive25d continues to build its lead. At 600 metres, it runs at 167 km/h versus 155 km/h. At 1,000 metres, the X4 xDrive25d finishes in 27.65 s versus 29.79 s, with a 2.14 s lead. Both vehicles have similar top speeds (228 vs 214 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the X4 xDrive25d is capped at 230 km/h, the X4 xDrive20i at 215 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 (7.60 kg/hp vs 9.48 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.15 seconds. The 1.60 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 8,50 s).
X4 xDrive25d G02 goes from 0 to 100 km/h in 6,90 seconds (calibrated simulation).
