Off the line, the Boxster Manual hits 100 km/h in 5.47 s versus 6.65 s for the Bmw Z4 sDrive20i. At this point, the Boxster Manual leads by 1.18 s and sits roughly 13 m ahead.
At 200 metres, the Boxster Manual is doing 135 km/h against 126 km/h for the Bmw Z4 sDrive20i. The gap is 0.77 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster Manual crosses the line in 13.65 s versus 14.82 s. The 1.17 s gap represents roughly 50 m of track - a gap visible to the naked eye.
Past 400 metres, the Boxster Manual continues to build its lead. At 600 metres, it runs at 192 km/h versus 176 km/h. At 1,000 metres, the Boxster Manual finishes in 24.66 s versus 26.78 s, with a 2.12 s lead.
Both rivals are electronically governed, but not at the same level: the Boxster Manual is capped at 262 km/h, the Bmw Z4 sDrive20i at 240 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 (5.15 kg/hp vs 7.13 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.30 seconds. The 1.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
