Off the line, the Bmw 120d hits 100 km/h in 7.38 s versus 7.74 s for the Bmw 420i xDrive. Despite the faster sprint time, the Bmw 420i xDrive is 6 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw 420i xDrive is doing 115 km/h against 121 km/h for the Bmw 120d. The gap is 0.10 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 120d crosses the line in 15.41 s versus 15.61 s. The 0.20 s gap represents roughly 8 m of track - barely a car length.
Past 400 metres, the Bmw 120d continues to build its lead. At 600 metres, it runs at 168 km/h versus 160 km/h. At 1,000 metres, the Bmw 120d finishes in 27.90 s versus 28.71 s, with a 0.82 s lead. Both vehicles have similar top speeds (231 vs 234 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 120d is capped at 231 km/h, the Bmw 420i xDrive at 238 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 (7.63 kg/hp vs 8.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.85 seconds. The 0.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 120d F40 wins (7,38 s vs 7,74 s).
120d F40 goes from 0 to 100 km/h in 7,38 seconds (calibrated simulation).
