Porsche 718 Cayman S vs Bmw 530e G30 : which one is faster?

The launch: 0 to 100 km/h

Off the line, the 718 Cayman S hits 100 km/h in 4.17 s versus 6.21 s for the Bmw 530e. At this point, the 718 Cayman S leads by 2.05 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Cayman S is doing 156 km/h against 130 km/h for the Bmw 530e. The gap is 1.50 s. The challenger starts to claw back ground.

At 400 metres standing start, the 718 Cayman S crosses the line in 12.12 s versus 14.41 s. The 2.29 s gap represents roughly 99 m of track — a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 718 Cayman S continues to build its lead. At 600 metres, it runs at 215 km/h versus 182 km/h. At 1,000 metres, the 718 Cayman S finishes in 21.89 s versus 25.92 s, with a 4.03 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 718 Cayman S is capped at 285 km/h, the Bmw 530e at 225 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 (3.87 kg/hp vs 6.51 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.47 seconds. The 2.05 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
