The start: 0 to 100 km/h

Off the line, the 520i hits 100 km/h in 7.84 s versus 8.23 s for the XC40 B4. At this point, the 520i leads by 0.39 s and sits roughly 12 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 520i is doing 114 km/h against 115 km/h for the XC40 B4. The gap is 0.44 s. The gap remains stable from the start.

At 400 metres standing start, the 520i crosses the line in 15.68 s versus 16.10 s. The 0.42 s gap represents roughly 16 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 520i continues to build its lead. At 600 metres, it runs at 159 km/h versus 158 km/h. At 1,000 metres, the 520i finishes in 28.87 s versus 29.39 s, with a 0.52 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the XC40 B4 is capped at 180 km/h, the 520i 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 (8.17 kg/hp vs 8.75 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 0.39 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
