Portofino M vs Bmw M850i xDrive: chronicle of a drag race at 352 km/h
The launch: 0 to 100 km/h
Off the line, the Portofino M hits 100 km/h in 3.47 s versus 3.83 s for the Bmw M850i xDrive. At this point, the Portofino M leads by 0.36 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Portofino M is doing 178 km/h against 161 km/h for the Bmw M850i xDrive. The gap is 0.48 s. The gap remains stable from the start.
At 400 metres standing start, the Portofino M crosses the line in 10.86 s versus 11.74 s. The 0.88 s gap represents roughly 48 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Portofino M continues to build its lead. At 600 metres, it runs at 250 km/h versus 225 km/h. At 1,000 metres, the Portofino M finishes in 19.27 s versus 21.08 s, with a 1.82 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw M850i 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 (2.56 kg/hp vs 3.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.51 seconds. The 0.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Ferrari Portofino M is slightly faster than the Bmw M850i xDrive to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
