Off the line, the Bmw 120d xDrive hits 100 km/h in 7.13 s versus 7.17 s for the Bmw 520d. The 0.04 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 520d is doing 117 km/h against 119 km/h for the Bmw 120d xDrive. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 520d crosses the line in 15.20 s versus 15.21 s. The 0.01 s gap represents roughly 0 m of track
Past 400 metres, the situation changes. The Bmw 120d xDrive maxes out at 228 km/h while the Bmw 520d keeps accelerating towards 235 km/h. At 600 metres, the gap has dropped to 0.04 s.
Around 437 metres, both vehicles are level. This is the inversion point: the Bmw 120d xDrive overcomes its launch deficit thanks to a 7 km/h higher top speed.
At 1,000 metres, the Bmw 120d xDrive finishes in 27.99 s versus 28.10 s. The 0.10 s delta shows an extremely tight race.
Both rivals are electronically governed, but not at the same level: the Bmw 120d xDrive is capped at 230 km/h, the Bmw 520d at 235 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 (7.97 kg/hp vs 8.82 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.01 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 120d xDrive F40 and 520d G30 are neck and neck (7,13 s vs 7,17 s, no significant gap).
120d xDrive F40 goes from 0 to 100 km/h in 7,13 seconds (calibrated simulation).
120d xDrive F40: 190 hp, ratio 7,97 kg/hp. 520d G30: 190 hp, ratio 8,82 kg/hp.
120d xDrive F40: 228 km/h. 520d G30: 235 km/h.
