The start: 0 to 100 km/h

Off the line, the Boxster S hits 100 km/h in 5.07 s versus 5.44 s for the Megane 4 RS Trophy 300. At this point, the Boxster S leads by 0.37 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster S is doing 143 km/h against 140 km/h for the Megane 4 RS Trophy 300. The gap is 0.29 s. The gap remains stable from the start.

At 400 metres standing start, the Boxster S crosses the line in 13.18 s versus 13.56 s. The 0.37 s gap represents roughly 18 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 199 km/h versus 195 km/h. At 1,000 metres, the Boxster S finishes in 23.72 s versus 24.36 s, with a 0.64 s lead. Both vehicles have similar top speeds (272 vs 260 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 272 km/h, the Megane 4 RS Trophy 300 at 260 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 (4.39 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 0.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
