Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the 218d hits 100 km/h in 8.35 s versus 9.13 s for the 318d. The 0.78 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 218d is doing 114 km/h against 109 km/h for the 318d. The gap is 0.11 s. The challenger starts to claw back ground.

At 400 metres standing start, the 218d crosses the line in 16.17 s versus 16.56 s. The 0.38 s gap represents roughly 14 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 218d continues to build its lead. At 600 metres, it runs at 158 km/h versus 151 km/h. At 1,000 metres, the 218d finishes in 29.45 s versus 30.51 s, with a 1.06 s lead. Both vehicles have similar top speeds (213 vs 209 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 218d is capped at 213 km/h, the 318d at 210 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 (9.47 kg/hp vs 10.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.33 seconds. The 0.78 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
