Off the line, the Roma hits 100 km/h in 3.43 s versus 7.44 s for the 420i. At this point, the Roma leads by 4.01 s and sits roughly 15 m ahead.
At 200 metres, the Roma is doing 182 km/h against 117 km/h for the 420i. The gap is 2.74 s. The challenger starts to claw back ground.
At 400 metres standing start, the Roma crosses the line in 10.68 s versus 15.38 s. The 4.70 s gap represents roughly 175 m of track - a gap visible to the naked eye.
Past 400 metres, the Roma continues to build its lead. At 600 metres, it runs at 256 km/h versus 163 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 28.23 s, with a 9.35 s lead.
Electronically capped at 240 km/h, the 420i never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.37 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 12.15 seconds. The 4.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Roma wins (3,43 s vs 7,44 s).
Roma goes from 0 to 100 km/h in 3,43 seconds (calibrated simulation).
