Off the line, the Boxster hits 100 km/h in 5.60 s versus 6.63 s for the Bmw Z4 sDrive20i. At this point, the Boxster leads by 1.03 s and sits roughly 7 m ahead.
At 200 metres, the Boxster is doing 134 km/h against 123 km/h for the Bmw Z4 sDrive20i. The gap is 0.54 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster crosses the line in 13.86 s versus 14.82 s. The 0.96 s gap represents roughly 40 m of track — a gap visible to the naked eye.
Past 400 metres, the Boxster continues to build its lead. At 600 metres, it runs at 185 km/h versus 170 km/h. At 1,000 metres, the Boxster finishes in 25.21 s versus 27.16 s, with a 1.95 s lead. Both vehicles have similar top speeds (252 vs 238 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Boxster is capped at 262 km/h, the Bmw Z4 sDrive20i at 241 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 7.21 kg/hp) and transmission (Unknown vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.69 seconds. The 1.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
