Megane 3 RS 265 vs 508 PureTech 225 EAT8: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Megane 3 RS 265 hits 100 km/h in 6.08 s versus 7.18 s for the 508 PureTech 225 EAT8. At this point, the Megane 3 RS 265 leads by 1.10 s and sits roughly 11 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Megane 3 RS 265 is doing 137 km/h against 124 km/h for the 508 PureTech 225 EAT8. The gap is 0.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the Megane 3 RS 265 crosses the line in 14.03 s versus 15.28 s. The 1.25 s gap represents roughly 52 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Megane 3 RS 265 continues to build its lead. At 600 metres, it runs at 193 km/h versus 172 km/h. At 1,000 metres, the Megane 3 RS 265 finishes in 24.97 s versus 27.49 s, with a 2.52 s lead. Both vehicles have similar top speeds (250 vs 240 km/h), preventing any comeback.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Megane 3 RS 265 never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.19 kg/hp vs 6.88 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.07 seconds. The 1.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Renault Megane 3 RS 265 has a clear edge over the Peugeot 508 PureTech 225 EAT8 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
