Off the line, the Bmw Z4 sDrive30i hits 100 km/h in 5.45 s versus 5.60 s for the Boxster. The 0.15 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw Z4 sDrive30i is doing 136 km/h against 134 km/h for the Boxster. The gap is 0.07 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw Z4 sDrive30i crosses the line in 13.70 s versus 13.86 s. The 0.16 s gap represents roughly 7 m of track — barely a car length.
Past 400 metres, the Bmw Z4 sDrive30i continues to build its lead. At 600 metres, it runs at 189 km/h versus 185 km/h. At 1,000 metres, the Bmw Z4 sDrive30i finishes in 24.81 s versus 25.21 s, with a 0.39 s lead. Both vehicles have similar top speeds (252 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 is capped at 262 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 (5.15 kg/hp vs 5.54 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.61 seconds. The 0.15 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.
