Off the line, the Bmw X3 xDrive30i hits 100 km/h in 6.35 s versus 7.15 s for the Bmw 120d. At this point, the Bmw X3 xDrive30i leads by 0.80 s and sits roughly 16 m ahead.
At 200 metres, the Bmw X3 xDrive30i is doing 126 km/h against 124 km/h for the Bmw 120d. The gap is 0.65 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X3 xDrive30i crosses the line in 14.56 s versus 15.30 s. The 0.74 s gap represents roughly 31 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X3 xDrive30i continues to build its lead. At 600 metres, it runs at 175 km/h versus 172 km/h. At 1,000 metres, the Bmw X3 xDrive30i finishes in 26.56 s versus 27.53 s, with a 0.98 s lead. Both vehicles have similar top speeds (240 vs 228 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw X3 xDrive30i is capped at 240 km/h, the Bmw 120d at 228 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 (6.81 kg/hp vs 7.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.99 seconds. The 0.80 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.
