The start: 0 to 100 km/h

Off the line, the 520d hits 100 km/h in 7.50 s versus 8.62 s for the 218i. At this point, the 520d leads by 1.12 s and sits roughly 16 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 520d is doing 117 km/h against 113 km/h for the 218i. The gap is 0.70 s. The challenger starts to claw back ground.

At 400 metres standing start, the 520d crosses the line in 15.49 s versus 16.35 s. The 0.86 s gap represents roughly 33 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 162 km/h versus 157 km/h. At 1,000 metres, the 520d finishes in 28.46 s versus 29.76 s, with a 1.30 s lead.

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 218i at 215 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 9.64 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.97 seconds. The 1.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
