Off the line, the Bmw M340i xDrive hits 100 km/h in 4.32 s versus 7.21 s for the Bmw 520d. At this point, the Bmw M340i xDrive leads by 2.89 s and sits roughly 18 m ahead.
At 200 metres, the Bmw M340i xDrive is doing 147 km/h against 118 km/h for the Bmw 520d. The gap is 1.70 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M340i xDrive crosses the line in 12.46 s versus 15.24 s. The 2.78 s gap represents roughly 108 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M340i xDrive continues to build its lead. At 600 metres, it runs at 206 km/h versus 163 km/h. At 1,000 metres, the Bmw M340i xDrive finishes in 22.65 s versus 28.10 s, with a 5.45 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw M340i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 520d 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 (4.77 kg/hp vs 8.68 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.95 seconds. The 2.89 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.
