Off the line, the Bmw X7 xDrive50i hits 100 km/h in 5.33 s versus 7.05 s for the Bmw 320i. At this point, the Bmw X7 xDrive50i leads by 1.72 s and sits roughly 8 m ahead.
At 200 metres, the Bmw X7 xDrive50i is doing 137 km/h against 119 km/h for the Bmw 320i. The gap is 0.86 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X7 xDrive50i crosses the line in 13.57 s versus 15.11 s. The 1.54 s gap represents roughly 62 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X7 xDrive50i continues to build its lead. At 600 metres, it runs at 190 km/h versus 166 km/h. At 1,000 metres, the Bmw X7 xDrive50i finishes in 24.64 s versus 27.81 s, with a 3.17 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw X7 xDrive50i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 320i at 235 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 (5.32 kg/hp vs 7.93 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.54 seconds. The 1.72 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.
