Ferrari Portofino vs Porsche 911 Turbo S 991.2: which is truly faster?

Off the line, the 911 Turbo S hits 100 km/h in 2.94 s versus 3.55 s for the Portofino. At this point, the 911 Turbo S leads by 0.61 s and sits roughly 8 m ahead.

At 200 metres, the 911 Turbo S is doing 176 km/h against 177 km/h for the Portofino. The gap is 0.40 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Turbo S crosses the line in 10.55 s versus 10.92 s. The 0.37 s gap represents roughly 23 m of track — two to three car lengths.

Past 400 metres, the gap narrows. The 911 Turbo S maxes out at 326 km/h while the Portofino keeps accelerating towards 348 km/h. At 600 metres, the gap has dropped to 0.32 s.

At 1,000 metres, the 911 Turbo S finishes in 19.14 s versus 19.36 s, with just 0.22 s to spare. The Portofino fails to fully close the launch gap.

On paper, the Portofino combines 600 hp, 760 Nm and 1,545 kg — a clear theoretical edge over the 911 Turbo S. Yet the 911 Turbo S launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the 911 Turbo S has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs — exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.

Electronically capped at 330 (i.e. 205 mph — industry threshold) km/h, the 911 Turbo S 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 2.72 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 4.72 seconds. The 0.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
