Off the line, the Z4 sDrive30i hits 100 km/h in 5.45 s versus 5.47 s for the Boxster Manual. The 0.02 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Boxster Manual is doing 135 km/h against 136 km/h for the Z4 sDrive30i. The gap is 0.02 s. The gap remains stable from the start.
At 400 metres standing start, the Boxster Manual crosses the line in 13.65 s versus 13.70 s. The 0.05 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the Boxster Manual continues to build its lead. At 600 metres, it runs at 192 km/h versus 189 km/h. At 1,000 metres, the Boxster Manual finishes in 24.66 s versus 24.81 s, with a 0.15 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 Manual is capped at 262 km/h, the 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 (5.15 kg/hp vs 5.54 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.46 seconds. The 0.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
