Off the line, the Bmw 420i hits 100 km/h in 7.44 s versus 7.74 s for the Bmw 520d xDrive Touring. At this point, the Bmw 420i leads by 0.30 s and sits roughly 3 m ahead.
At 200 metres, the Bmw 420i is doing 117 km/h against 115 km/h for the Bmw 520d xDrive Touring. The gap is 0.14 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 420i crosses the line in 15.38 s versus 15.65 s. The 0.27 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the Bmw 420i continues to build its lead. At 600 metres, it runs at 163 km/h versus 159 km/h. At 1,000 metres, the Bmw 420i finishes in 28.23 s versus 28.90 s, with a 0.67 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 520d xDrive Touring is capped at 222 km/h, the Bmw 420i at 240 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 (9.21 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.92 seconds. The 0.30 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.
