Review: 2021 Porsche 911 Turbo S – The Perfect Sports Car Is Now Even Better.
The speedometer eventually indicated 194 mph (313 km/h), and if the driver had kept it floored, we have no doubt he would have eventually seen 205 mph (330 km/h), which, according to Porsche, is its official top speed.
Aided by the advanced aerodynamics and 3.8-liter twin-turbocharged flat-six engine, which has evolved from the Carrera’s 3.0-liter mill and puts out 641 HP (650 PS / 478 kW) and 590 lb-ft (800 Nm) of torque, the new 911 Turbo S rockets to 60 mph (96 km/h) in well under 3 seconds.
