Off the line, the 225i xDrive hits 100 km/h in 6.41 s versus 6.55 s for the 525d. At this point, the 225i xDrive leads by 0.14 s and sits roughly 5 m ahead.
At 200 metres, the 225i xDrive is doing 128 km/h against 129 km/h for the 525d. The gap is 0.16 s. The gap remains stable from the start.
At 400 metres standing start, the 225i xDrive crosses the line in 14.60 s versus 14.73 s. The 0.12 s gap represents roughly 6 m of track - barely a car length.
Past 400 metres, the situation changes. The 225i xDrive maxes out at 235 km/h while the 525d keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.07 s.
Around 783 metres, both vehicles are level. This is the inversion point: the 525d overcomes its launch deficit thanks to a 15 km/h higher top speed.
At 1,000 metres, the 525d finishes in 26.39 s versus 26.49 s. The 0.10 s delta shows an extremely tight race.
The 225i xDrive features all-wheel drive (AWD) against the 525d’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the 225i xDrive is capped at 235 km/h, the 525d at 250 (i.e. 155 mph - industry threshold) 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 (6.58 kg/hp vs 6.90 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 0.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
