Off the line, the Bmw X7 M50d hits 100 km/h in 5.49 s versus 7.92 s for the Bmw X3 xDrive20d. At this point, the Bmw X7 M50d leads by 2.43 s and sits roughly 13 m ahead.
At 200 metres, the Bmw X7 M50d is doing 132 km/h against 114 km/h for the Bmw X3 xDrive20d. The gap is 1.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X7 M50d crosses the line in 13.82 s versus 15.76 s. The 1.95 s gap represents roughly 73 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X7 M50d continues to build its lead. At 600 metres, it runs at 184 km/h versus 156 km/h. At 1,000 metres, the Bmw X7 M50d finishes in 25.28 s versus 29.22 s, with a 3.95 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw X7 M50d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw X3 xDrive20d at 213 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 (6.15 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 13.46 seconds. The 2.43 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.
