Off the line, the Megane 4 RS Trophy 300 hits 100 km/h in 5.44 s versus 6.48 s for the Bmw 125d. At this point, the Megane 4 RS Trophy 300 leads by 1.04 s and sits roughly 12 m ahead.
At 200 metres, the Megane 4 RS Trophy 300 is doing 140 km/h against 130 km/h for the Bmw 125d. The gap is 0.74 s. The challenger starts to claw back ground.
At 400 metres standing start, the Megane 4 RS Trophy 300 crosses the line in 13.56 s versus 14.67 s. The 1.12 s gap represents roughly 49 m of track — a gap visible to the naked eye.
Past 400 metres, the Megane 4 RS Trophy 300 continues to build its lead. At 600 metres, it runs at 195 km/h versus 180 km/h. At 1,000 metres, the Megane 4 RS Trophy 300 finishes in 24.36 s versus 26.39 s, with a 2.04 s lead.
Both rivals are electronically governed, but not at the same level: the Megane 4 RS Trophy 300 is capped at 260 km/h, the Bmw 125d at 240 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 (4.83 kg/hp vs 6.61 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.81 seconds. The 1.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
