IS 350 F Sport RWD vs Megane 3 RS 265: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the IS 350 F Sport RWD hits 100 km/h in 5.76 s versus 6.08 s for the Megane 3 RS 265. At this point, the IS 350 F Sport RWD leads by 0.33 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the IS 350 F Sport RWD is doing 137 km/h against 137 km/h for the Megane 3 RS 265. The gap is 0.17 s. The challenger starts to claw back ground.
At 400 metres standing start, the IS 350 F Sport RWD crosses the line in 13.83 s versus 14.03 s. The 0.20 s gap represents roughly 10 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the IS 350 F Sport RWD continues to build its lead. At 600 metres, it runs at 193 km/h versus 193 km/h. At 1,000 metres, the IS 350 F Sport RWD finishes in 24.69 s versus 24.97 s, with a 0.28 s lead. Both vehicles have similar top speeds (250 vs 250 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals share the same electronic speed cap: the IS 350 F Sport RWD and the Megane 3 RS 265 are governed to 250 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 (5.58 kg/hp vs 5.19 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.63 seconds. The 0.33 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 350 F Sport RWD is slightly faster than the Renault Megane 3 RS 265 to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
