Bmw M440i vs Boxster S: chronicle of a drag race at 272 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M440i hits 100 km/h in 4.83 s versus 5.07 s for the Boxster S. The 0.25 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Bmw M440i is doing 146 km/h against 143 km/h for the Boxster S. The gap is 0.14 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M440i crosses the line in 12.93 s versus 13.18 s. The 0.26 s gap represents roughly 13 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M440i continues to build its lead. At 600 metres, it runs at 205 km/h versus 199 km/h. At 1,000 metres, the Bmw M440i finishes in 23.15 s versus 23.72 s, with a 0.57 s lead. Despite a higher top speed (272 km/h), the Boxster S never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M440i is capped at 250 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 (4.53 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 0.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M440i is slightly faster than the Porsche Boxster S to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
