The start: 0 to 100 km/h

Off the line, the 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 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 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 M440i continues to build its lead. At 600 metres, it runs at 205 km/h versus 199 km/h. At 1,000 metres, the 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 M440i 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 (4.53 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.
