Off the line, the Boxster S hits 100 km/h in 5.08 s versus 5.35 s for the Bmw Z4 sDrive30i. The 0.27 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Boxster S is doing 143 km/h against 137 km/h for the Bmw Z4 sDrive30i. The gap is 0.18 s. The gap remains stable from the start.
At 400 metres standing start, the Boxster S crosses the line in 13.23 s versus 13.60 s. The 0.37 s gap represents roughly 17 m of track - two to three car lengths.
Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 198 km/h versus 191 km/h. At 1,000 metres, the Boxster S finishes in 23.87 s versus 24.59 s, with a 0.73 s lead. Both vehicles have similar top speeds (262 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 274 km/h, the Bmw Z4 sDrive30i 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.32 kg/hp vs 5.48 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.13 seconds. The 0.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster S 981 wins (5,08 s vs 5,35 s).
Boxster S 981 goes from 0 to 100 km/h in 5,08 seconds (calibrated simulation).
