Boxster S Manual vs Megane 3 RS 265: chronicle of a drag race at 269 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster S Manual hits 100 km/h in 4.85 s versus 6.08 s for the Megane 3 RS 265. At this point, the Boxster S Manual leads by 1.24 s and sits roughly 15 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster S Manual is doing 145 km/h against 137 km/h for the Megane 3 RS 265. The gap is 0.84 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S Manual crosses the line in 12.93 s versus 14.03 s. The 1.10 s gap represents roughly 51 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster S Manual continues to build its lead. At 600 metres, it runs at 202 km/h versus 193 km/h. At 1,000 metres, the Boxster S Manual finishes in 23.37 s versus 24.97 s, with a 1.60 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Boxster S Manual is capped at 274 km/h, the Megane 3 RS 265 at 250 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 (4.32 kg/hp vs 5.19 kg/hp) and transmission (Manual vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.63 seconds. The 1.24 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Boxster S Manual has a clear edge over the Renault Megane 3 RS 265 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
