Off the line, the Bmw X3 xDrive30i hits 100 km/h in 6.35 s versus 9.32 s for the Bmw 318d Steptronic. At this point, the Bmw X3 xDrive30i leads by 2.97 s and sits roughly 27 m ahead.
At 200 metres, the Bmw X3 xDrive30i is doing 126 km/h against 111 km/h for the Bmw 318d Steptronic. The gap is 1.64 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 16.91 s. The 2.35 s gap represents roughly 87 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 153 km/h. At 1,000 metres, the Bmw X3 xDrive30i finishes in 26.56 s versus 30.62 s, with a 4.07 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw X3 xDrive30i is capped at 240 km/h, the Bmw 318d Steptronic at 212 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 9.66 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.08 seconds. The 2.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 xDrive30i G01 wins (6,35 s vs 9,32 s).
X3 xDrive30i G01 goes from 0 to 100 km/h in 6,35 seconds (calibrated simulation).
