Off the line, the Roma hits 100 km/h in 3.43 s versus 7.04 s for the Bmw 420d. At this point, the Roma leads by 3.61 s and sits roughly 14 m ahead.
At 200 metres, the Roma is doing 182 km/h against 119 km/h for the Bmw 420d. The gap is 2.54 s. The challenger starts to claw back ground.
At 400 metres standing start, the Roma crosses the line in 10.68 s versus 15.10 s. The 4.43 s gap represents roughly 168 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 166 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 27.77 s, with a 8.90 s lead.
Electronically capped at 240 km/h, the Bmw 420d 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 8.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.60 seconds. The 3.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
