Off the line, the 520d Touring hits 100 km/h in 7.47 s versus 7.75 s for the 420d Convertible. At this point, the 520d Touring leads by 0.28 s and sits roughly 6 m ahead.
At 200 metres, the 520d Touring is doing 115 km/h against 116 km/h for the 420d Convertible. The gap is 0.23 s. The gap remains stable from the start.
At 400 metres standing start, the 520d Touring crosses the line in 15.42 s versus 15.64 s. The 0.22 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the gap narrows. The 520d Touring maxes out at 225 km/h while the 420d Convertible keeps accelerating towards 236 km/h. At 600 metres, the gap has dropped to 0.18 s.
At 1,000 metres, the 520d Touring finishes in 28.59 s versus 28.69 s, with just 0.10 s to spare. The 420d Convertible fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the 420d Convertible is capped at 236 km/h, the 520d Touring at 225 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 (9.34 kg/hp vs 9.16 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 0.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
