The start: 0 to 100 km/h

Off the line, the 520d Touring hits 100 km/h in 7.47 s versus 9.57 s for the 218i Convertible. At this point, the 520d Touring leads by 2.10 s and sits roughly 27 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 520d Touring is doing 115 km/h against 109 km/h for the 218i Convertible. The gap is 1.25 s. The challenger starts to claw back ground.

At 400 metres standing start, the 520d Touring crosses the line in 15.42 s versus 17.01 s. The 1.59 s gap represents roughly 58 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 520d Touring continues to build its lead. At 600 metres, it runs at 160 km/h versus 150 km/h. At 1,000 metres, the 520d Touring finishes in 28.59 s versus 30.99 s, with a 2.40 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 520d Touring is capped at 225 km/h, the 218i Convertible at 207 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 (9.16 kg/hp vs 11.47 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.88 seconds. The 2.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
