Off the line, the 420d hits 100 km/h in 7.04 s versus 7.62 s for the 420i Steptronic Gran Coupe. At this point, the 420d leads by 0.58 s and sits roughly 9 m ahead.
At 200 metres, the 420d is doing 119 km/h against 118 km/h for the 420i Steptronic Gran Coupe. The gap is 0.39 s. The challenger starts to claw back ground.
At 400 metres standing start, the 420d crosses the line in 15.10 s versus 15.55 s. The 0.45 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the 420d continues to build its lead. At 600 metres, it runs at 166 km/h versus 164 km/h. At 1,000 metres, the 420d finishes in 27.77 s versus 28.34 s, with a 0.57 s lead. Both vehicles have similar top speeds (240 vs 236 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 420d is capped at 240 km/h, the 420i Steptronic Gran Coupe at 236 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 (8.45 kg/hp vs 8.53 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 0.58 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420d F32 wins (7,04 s vs 7,62 s).
420d F32 goes from 0 to 100 km/h in 7,04 seconds (calibrated simulation).
