Off the line, the Bmw Z4 M40i hits 100 km/h in 4.54 s versus 5.07 s for the Boxster S. At this point, the Bmw Z4 M40i leads by 0.53 s and sits roughly 5 m ahead.
At 200 metres, the Bmw Z4 M40i is doing 147 km/h against 143 km/h for the Boxster S. The gap is 0.36 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw Z4 M40i crosses the line in 12.70 s versus 13.18 s. The 0.49 s gap represents roughly 24 m of track — two to three car lengths.
Past 400 metres, the Bmw Z4 M40i continues to build its lead. At 600 metres, it runs at 205 km/h versus 199 km/h. At 1,000 metres, the Bmw Z4 M40i finishes in 22.95 s versus 23.72 s, with a 0.77 s lead. Despite a higher top speed (272 km/h), the Boxster S never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the Bmw Z4 M40i is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Boxster S at 272 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 (4.51 kg/hp vs 4.39 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.54 seconds. The 0.53 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.
