Off the line, the S60 B4 hits 100 km/h in 8.00 s versus 8.14 s for the 420i Convertible. At this point, the S60 B4 leads by 0.14 s and sits roughly 4 m ahead.
At 200 metres, the S60 B4 is doing 115 km/h against 115 km/h for the 420i Convertible. The gap is 0.14 s. The gap remains stable from the start.
At 400 metres standing start, the S60 B4 crosses the line in 15.82 s versus 15.96 s. The 0.15 s gap represents roughly 6 m of track - barely a car length.
Past 400 metres, the gap narrows. The S60 B4 maxes out at 180 km/h while the 420i Convertible keeps accelerating towards 236 km/h. At 600 metres, the gap has dropped to 0.14 s.
At 1,000 metres, the S60 B4 finishes in 28.87 s versus 28.97 s, with just 0.09 s to spare. The 420i Convertible 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 420i Convertible at 236 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 9.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.10 seconds. The 0.14 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.
