Off the line, the Roma hits 100 km/h in 3.43 s versus 4.59 s for the Mustang GT 449. At this point, the Roma leads by 1.15 s and sits roughly 12 m ahead.
At 200 metres, the Roma is doing 182 km/h against 154 km/h for the Mustang GT 449. The gap is 1.16 s. The gap remains stable from the start.
At 400 metres standing start, the Roma crosses the line in 10.68 s versus 12.48 s. The 1.80 s gap represents roughly 93 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 216 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 22.20 s, with a 3.32 s lead.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Mustang GT 449 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 3.88 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.40 seconds. The 1.15 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 4,58 s).
Roma goes from 0 to 100 km/h in 3,43 seconds (calibrated simulation).
