Off the line, the 520i hits 100 km/h in 7.84 s versus 8.00 s for the S60 B4. At this point, the 520i leads by 0.16 s and sits roughly 6 m ahead.
At 200 metres, the 520i is doing 114 km/h against 115 km/h for the S60 B4. The gap is 0.19 s. The gap remains stable from the start.
At 400 metres standing start, the 520i crosses the line in 15.68 s versus 15.82 s. The 0.13 s gap represents roughly 5 m of track - barely a car length.
Past 400 metres, the gap narrows. The S60 B4 maxes out at 180 km/h while the 520i keeps accelerating towards 231 km/h. At 600 metres, the gap has dropped to 0.08 s.
At 1,000 metres, the 520i finishes in 28.87 s versus 28.87 s, with just 0.01 s to spare. The S60 B4 fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the S60 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 (8.27 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 13.04 seconds. The 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
