Portofino M vs Bmw X5 M50i: 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 4.34 s for the Bmw X5 M50i. At this point, the Portofino M leads by 0.87 s and sits roughly 7 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Portofino M is doing 178 km/h against 150 km/h for the Bmw X5 M50i. The gap is 0.91 s. The gap remains stable from the start.
At 400 metres standing start, the Portofino M crosses the line in 10.86 s versus 12.43 s. The 1.57 s gap represents roughly 79 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 209 km/h. At 1,000 metres, the Portofino M finishes in 19.27 s versus 22.50 s, with a 3.24 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw X5 M50i 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 4.25 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.38 seconds. The 0.87 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Ferrari Portofino M has a clear edge over the Bmw X5 M50i to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
