Portofino vs 911 Turbo Cabriolet: chronicle of a drag race at 348 km/h
The launch: 0 to 100 km/h
Off the line, the Portofino hits 100 km/h in 3.55 s versus 3.65 s for the 911 Turbo Cabriolet. The 0.10 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Portofino is doing 177 km/h against 166 km/h for the 911 Turbo Cabriolet. The gap is 0.23 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Portofino crosses the line in 10.92 s versus 11.42 s. The 0.49 s gap represents roughly 28 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Portofino continues to build its lead. At 600 metres, it runs at 249 km/h versus 230 km/h. At 1,000 metres, the Portofino finishes in 19.36 s versus 20.54 s, with a 1.19 s lead.
What the numbers don’t tell you
Electronically capped at 312 km/h, the 911 Turbo Cabriolet 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 (2.58 kg/hp vs 3.24 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.18 seconds. The 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Ferrari Portofino is slightly faster than the Porsche 911 Turbo Cabriolet to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
