The start: 0 to 100 km/h

Off the line, the 520d hits 100 km/h in 7.17 s versus 8.32 s for the V 300 d 4MATIC. At this point, the 520d leads by 1.15 s and sits roughly 13 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 520d is doing 117 km/h against 114 km/h for the V 300 d 4MATIC. The gap is 0.59 s. The challenger starts to claw back ground.

At 400 metres standing start, the 520d crosses the line in 15.20 s versus 16.03 s. The 0.83 s gap represents roughly 31 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 520d continues to build its lead. At 600 metres, it runs at 163 km/h versus 156 km/h. At 1,000 metres, the 520d finishes in 28.10 s versus 29.55 s, with a 1.45 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the V 300 d 4MATIC is capped at 217 km/h, the 520d 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 (9.44 kg/hp vs 8.82 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.08 seconds. The 1.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
