Off the line, the Bmw X3 xDrive30d hits 100 km/h in 5.62 s versus 7.12 s for the Bmw 120i. At this point, the Bmw X3 xDrive30d leads by 1.50 s and sits roughly 18 m ahead.
At 200 metres, the Bmw X3 xDrive30d is doing 130 km/h against 122 km/h for the Bmw 120i. The gap is 0.96 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X3 xDrive30d crosses the line in 13.96 s versus 15.22 s. The 1.26 s gap represents roughly 53 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X3 xDrive30d continues to build its lead. At 600 metres, it runs at 180 km/h versus 170 km/h. At 1,000 metres, the Bmw X3 xDrive30d finishes in 25.66 s versus 27.52 s, with a 1.86 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw X3 xDrive30d is capped at 245 km/h, the Bmw 120i at 225 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 (6.75 kg/hp vs 7.47 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.27 seconds. The 1.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 xDrive30d G01 wins (5,62 s vs 7,12 s).
X3 xDrive30d G01 goes from 0 to 100 km/h in 5,62 seconds (calibrated simulation).
