Off the line, the Bmw 420i hits 100 km/h in 7.44 s versus 8.23 s for the XC40 B4. At this point, the Bmw 420i leads by 0.79 s and sits roughly 15 m ahead.
At 200 metres, the Bmw 420i is doing 117 km/h against 115 km/h for the XC40 B4. The gap is 0.60 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 420i crosses the line in 15.38 s versus 16.10 s. The 0.72 s gap represents roughly 28 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 158 km/h. At 1,000 metres, the Bmw 420i finishes in 28.23 s versus 29.39 s, with a 1.16 s lead.
Both rivals are electronically governed, but not at the same level: the XC40 B4 is capped at 180 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 (8.17 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 13.40 seconds. The 0.79 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.
