CONFIDENCE 93%Why this result?
The Bmw M550d xDrive is faster at 0-100 km/h, but the Porsche 718 Boxster GTS compensates at high speed thanks to higher peak power or top speed. At 400 m, Porsche 718 Boxster GTS leads by 0.34 s.

Bmw M550d xDrive vs 718 Boxster GTS: chronicle of a drag race at 290 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M550d xDrive hits 100 km/h in 4.46 s versus 4.47 s for the 718 Boxster GTS. The 0.00 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the 718 Boxster GTS is doing 155 km/h against 146 km/h for the Bmw M550d xDrive. The gap is 0.09 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 718 Boxster GTS crosses the line in 12.32 s versus 12.66 s. The 0.34 s gap represents roughly 17 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 718 Boxster GTS continues to build its lead. At 600 metres, it runs at 217 km/h versus 204 km/h. At 1,000 metres, the 718 Boxster GTS finishes in 21.96 s versus 22.91 s, with a 0.95 s lead.
What the numbers don’t tell you
The Bmw M550d xDrive features all-wheel drive (AWD) against the 718 Boxster GTS’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Bmw M550d xDrive is capped at 250 km/h, the 718 Boxster GTS at 290 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 3.77 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.77 seconds. The 0.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M550d xDrive and Porsche 718 Boxster GTS are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
