Ferrari 488 GTB 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 3.03 s for the 488 GTB. The 0.09 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the 488 GTB is doing 188 km/h against 176 km/h for the 911 Turbo S. The gap is 0.12 s. The gap remains stable from the start.

At 400 metres standing start, the 488 GTB crosses the line in 10.20 s versus 10.55 s. The 0.35 s gap represents roughly 21 m of track - two to three car lengths.

Past 400 metres, the 488 GTB continues to build its lead. At 600 metres, it runs at 261 km/h versus 245 km/h. At 1,000 metres, the 488 GTB finishes in 18.27 s versus 19.14 s, with a 0.87 s lead. Both vehicles have similar top speeds (339 vs 326 km/h), preventing any comeback.

On paper, the 488 GTB combines 669 hp, 760 Nm and 1,470 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 (2.20 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 4.23 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
