718 Spyder vs Bmw M550d xDrive: chronicle of a drag race at 310 km/h
The launch: 0 to 100 km/h
Off the line, the 718 Spyder hits 100 km/h in 4.27 s versus 4.46 s for the Bmw M550d xDrive. At this point, the 718 Spyder leads by 0.20 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 718 Spyder is doing 156 km/h against 146 km/h for the Bmw M550d xDrive. The gap is 0.30 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 718 Spyder crosses the line in 12.04 s versus 12.66 s. The 0.62 s gap represents roughly 31 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 718 Spyder continues to build its lead. At 600 metres, it runs at 224 km/h versus 204 km/h. At 1,000 metres, the 718 Spyder finishes in 21.49 s versus 22.91 s, with a 1.43 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw M550d xDrive never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.46 kg/hp vs 4.61 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.77 seconds. The 0.20 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 718 Spyder 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.
