The start: 0 to 100 km/h

Off the line, the 225d hits 100 km/h in 6.40 s versus 6.55 s for the 525d. At this point, the 225d leads by 0.15 s and sits roughly 1 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 225d is doing 130 km/h against 129 km/h for the 525d. The gap is 0.08 s. The gap remains stable from the start.

At 400 metres standing start, the 225d crosses the line in 14.61 s versus 14.73 s. The 0.12 s gap represents roughly 5 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 225d continues to build its lead. At 600 metres, it runs at 180 km/h versus 180 km/h. At 1,000 metres, the 225d finishes in 26.28 s versus 26.39 s, with a 0.11 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 243 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 525d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 225d at 243 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 (6.90 kg/hp vs 6.58 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.96 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
