The start: 0 to 100 km/h

Off the line, the Megane 4 RS Trophy 300 hits 100 km/h in 5.44 s versus 7.37 s for the 120d. At this point, the Megane 4 RS Trophy 300 leads by 1.93 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Megane 4 RS Trophy 300 is doing 140 km/h against 121 km/h for the 120d. The gap is 1.15 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 15.45 s. The 1.89 s gap represents roughly 76 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Megane 4 RS Trophy 300 continues to build its lead. At 600 metres, it runs at 195 km/h versus 167 km/h. At 1,000 metres, the Megane 4 RS Trophy 300 finishes in 24.36 s versus 28.02 s, with a 3.67 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Megane 4 RS Trophy 300 is capped at 260 km/h, the 120d at 231 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 7.63 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.63 seconds. The 1.93 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
