The start: 0 to 100 km/h

Off the line, the 520d hits 100 km/h in 7.50 s versus 8.41 s for the 118d. At this point, the 520d leads by 0.91 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 520d is doing 117 km/h against 115 km/h for the 118d. The gap is 0.68 s. The challenger starts to claw back ground.

At 400 metres standing start, the 520d crosses the line in 15.49 s versus 16.25 s. The 0.76 s gap represents roughly 30 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 520d continues to build its lead. At 600 metres, it runs at 162 km/h versus 159 km/h. At 1,000 metres, the 520d finishes in 28.46 s versus 29.46 s, with a 1.01 s lead. Both vehicles have similar top speeds (232 vs 218 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 520d is capped at 235 km/h, the 118d at 218 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 (8.39 kg/hp vs 9.37 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.51 seconds. The 0.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
