Off the line, the Roma hits 100 km/h in 3.43 s versus 5.44 s for the Megane 4 RS Trophy 300. At this point, the Roma leads by 2.01 s and sits roughly 16 m ahead.
At 200 metres, the Roma is doing 182 km/h against 140 km/h for the Megane 4 RS Trophy 300. The gap is 1.81 s. The challenger starts to claw back ground.
At 400 metres standing start, the Roma crosses the line in 10.68 s versus 13.56 s. The 2.88 s gap represents roughly 132 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 195 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 24.36 s, with a 5.48 s lead.
Electronically capped at 260 km/h, the Megane 4 RS Trophy 300 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 4.83 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.94 seconds. The 2.01 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 5,44 s).
Roma goes from 0 to 100 km/h in 3,43 seconds (calibrated simulation).
