Off the line, the Megane 4 RS Trophy-R hits 100 km/h in 5.48 s versus 6.15 s for the 125i. At this point, the Megane 4 RS Trophy-R leads by 0.67 s and sits roughly 7 m ahead.
At 200 metres, the Megane 4 RS Trophy-R is doing 140 km/h against 131 km/h for the 125i. The gap is 0.50 s. The challenger starts to claw back ground.
At 400 metres standing start, the Megane 4 RS Trophy-R crosses the line in 13.48 s versus 14.35 s. The 0.87 s gap represents roughly 39 m of track - a gap visible to the naked eye.
Past 400 metres, the Megane 4 RS Trophy-R continues to build its lead. At 600 metres, it runs at 198 km/h versus 182 km/h. At 1,000 metres, the Megane 4 RS Trophy-R finishes in 24.14 s versus 25.91 s, with a 1.77 s lead.
Both rivals are electronically governed, but not at the same level: the Megane 4 RS Trophy-R is capped at 260 km/h, the 125i at 243 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 (4.35 kg/hp vs 6.25 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.35 seconds. The 0.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Megane 4 RS Trophy-R wins (5,48 s vs 6,15 s).
Megane 4 RS Trophy-R goes from 0 to 100 km/h in 5,48 seconds (calibrated simulation).
