Off the line, the Bmw Z4 M40i hits 100 km/h in 4.55 s versus 5.60 s for the Boxster. At this point, the Bmw Z4 M40i leads by 1.05 s and sits roughly 9 m ahead.
At 200 metres, the Bmw Z4 M40i is doing 147 km/h against 134 km/h for the Boxster. The gap is 0.72 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw Z4 M40i crosses the line in 12.71 s versus 13.86 s. The 1.15 s gap represents roughly 52 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw Z4 M40i continues to build its lead. At 600 metres, it runs at 204 km/h versus 185 km/h. At 1,000 metres, the Bmw Z4 M40i finishes in 23.00 s versus 25.21 s, with a 2.21 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 252 km/h), preventing any comeback.
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 at 262 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 (4.57 kg/hp vs 5.15 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.61 seconds. The 1.05 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.
