Renault Megane 4 RS Trophy 300 vs Cupra Born: which is truly faster?

Off the line, the Megane 4 RS Trophy 300 hits 100 km/h in 5.44 s versus 7.23 s for the Born. Despite lacking instant torque, 300 hp of power compensates. At this point, the Megane 4 RS Trophy 300 leads by 1.79 s and sits roughly 15 m ahead.

At 200 metres, the Megane 4 RS Trophy 300 is doing 140 km/h against 122 km/h for the Born. The gap is 1.12 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 15.39 s. The 1.83 s gap represents roughly 74 m of track - a gap visible to the naked eye.

Past 400 metres, the Megane 4 RS Trophy 300 continues to build its lead. At 600 metres, it runs at 195 km/h versus 160 km/h. At 1,000 metres, the Megane 4 RS Trophy 300 finishes in 24.36 s versus 28.98 s, with a 4.62 s lead.

Both rivals are electronically governed, but not at the same level: the Megane 4 RS Trophy 300 is capped at 260 km/h, the Born at 160 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.41 seconds. The 1.79 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
