Off the line, the Bmw 320d xDrive Touring hits 100 km/h in 7.44 s versus 7.44 s for the Bmw 420i. The 0.00 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 420i is doing 117 km/h against 117 km/h for the Bmw 320d xDrive Touring. The gap is 0.09 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 420i crosses the line in 15.38 s versus 15.48 s. The 0.10 s gap represents roughly 4 m of track — barely a car length.
Past 400 metres, the Bmw 420i continues to build its lead. At 600 metres, it runs at 163 km/h versus 163 km/h. At 1,000 metres, the Bmw 420i finishes in 28.23 s versus 28.40 s, with a 0.18 s lead. Both vehicles have similar top speeds (225 vs 238 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 320d xDrive Touring is capped at 225 km/h, the Bmw 420i at 240 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 (8.89 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.25 seconds. The 0.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
