Off the line, the 520i Touring hits 100 km/h in 8.16 s versus 8.75 s for the 318d Touring. The 0.59 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 520i Touring is doing 114 km/h against 110 km/h for the 318d Touring. The gap is 0.08 s. The challenger starts to claw back ground.
At 400 metres standing start, the 520i Touring crosses the line in 15.95 s versus 16.26 s. The 0.31 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the 520i Touring continues to build its lead. At 600 metres, it runs at 158 km/h versus 153 km/h. At 1,000 metres, the 520i Touring finishes in 29.29 s versus 30.02 s, with a 0.73 s lead. Both vehicles have similar top speeds (222 vs 217 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 520i Touring is capped at 225 km/h, the 318d Touring at 217 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 (8.89 kg/hp vs 10.50 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.87 seconds. The 0.59 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
