Bmw M550d xDrive vs 718 Boxster S: chronicle of a drag race at 285 km/h
The launch: 0 to 100 km/h
Off the line, the 718 Boxster S hits 100 km/h in 4.16 s versus 4.46 s for the Bmw M550d xDrive. At this point, the 718 Boxster S leads by 0.30 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 718 Boxster S is doing 157 km/h against 146 km/h for the Bmw M550d xDrive. The gap is 0.30 s. The gap remains stable from the start.
At 400 metres standing start, the 718 Boxster S crosses the line in 12.06 s versus 12.66 s. The 0.60 s gap represents roughly 30 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 718 Boxster S continues to build its lead. At 600 metres, it runs at 218 km/h versus 204 km/h. At 1,000 metres, the 718 Boxster S finishes in 21.69 s versus 22.91 s, with a 1.22 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M550d xDrive is capped at 250 km/h, the 718 Boxster S at 285 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 (4.61 kg/hp vs 3.87 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.77 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 718 Boxster S is slightly faster than the Bmw M550d xDrive to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
