Porsche Cayenne (8-speed Tiptronic S) 958.1 vs Porsche 718 Boxster: which is truly faster?

Off the line, the 718 Boxster hits 100 km/h in 4.65 s versus 7.55 s for the Cayenne (8-speed Tiptronic S). At this point, the 718 Boxster leads by 2.91 s and sits roughly 19 m ahead.

At 200 metres, the 718 Boxster is doing 147 km/h against 119 km/h for the Cayenne (8-speed Tiptronic S). The gap is 1.75 s. The challenger starts to claw back ground.

At 400 metres standing start, the 718 Boxster crosses the line in 12.76 s versus 15.50 s. The 2.74 s gap represents roughly 108 m of track - a gap visible to the naked eye.

Past 400 metres, the 718 Boxster continues to build its lead. At 600 metres, it runs at 204 km/h versus 166 km/h. At 1,000 metres, the 718 Boxster finishes in 23.08 s versus 28.16 s, with a 5.08 s lead.

Both rivals are electronically governed, but not at the same level: the Cayenne (8-speed Tiptronic S) is capped at 230 km/h, the 718 Boxster at 274 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 (6.68 kg/hp vs 4.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.88 seconds. The 2.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
