Renault Megane 4 RS Trophy 300 vs Porsche Boxster 987: which is truly faster?

Off the line, the Megane 4 RS Trophy 300 hits 100 km/h in 5.44 s versus 5.71 s for the Boxster. The 0.27 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Megane 4 RS Trophy 300 is doing 140 km/h against 134 km/h for the Boxster. The gap is 0.15 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 13.88 s. The 0.32 s gap represents roughly 15 m of track - two to three car lengths.

Past 400 metres, the Megane 4 RS Trophy 300 continues to build its lead. At 600 metres, it runs at 195 km/h versus 189 km/h. At 1,000 metres, the Megane 4 RS Trophy 300 finishes in 24.36 s versus 25.03 s, with a 0.67 s lead. Both vehicles have similar top speeds (260 vs 261 km/h), preventing any comeback.

Both rivals share the same electronic speed cap: the Megane 4 RS Trophy 300 and the Boxster are governed to 260 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.83 kg/hp vs 5.27 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.70 seconds. The 0.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
