Porsche Taycan J1.1 vs Renault Megane 4 RS 280: which is truly faster?

Off the line, the Taycan hits 100 km/h in 5.13 s versus 5.80 s for the Megane 4 RS 280. The instant torque of 345 Nm from the electric motor makes the difference. At this point, the Taycan leads by 0.67 s and sits roughly 6 m ahead.

At 200 metres, the Taycan is doing 148 km/h against 138 km/h for the Megane 4 RS 280. The gap is 0.50 s. The challenger starts to claw back ground.

At 400 metres standing start, the Taycan crosses the line in 13.02 s versus 13.86 s. The 0.84 s gap represents roughly 40 m of track - a gap visible to the naked eye.

Past 400 metres, the Taycan continues to build its lead. At 600 metres, it runs at 215 km/h versus 194 km/h. At 1,000 metres, the Taycan finishes in 22.91 s versus 24.70 s, with a 1.79 s lead. Despite a higher top speed (250 (i.e. 155 mph - industry threshold) km/h), the Megane 4 RS 280 never recovers its launch deficit.

Both rivals are electronically governed, but not at the same level: the Taycan is capped at 230 km/h, the Megane 4 RS 280 at 250 (i.e. 155 mph - industry threshold) 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 8.37 seconds. The 0.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
