Is Porsche Understating The New 911 Carrera S’ Power Figures?

Toyota has recently made headlines for understating the true horsepower and torque of the new Supra. It appears that others might be following the same practice.

Motor Trend recently got its hands on the latest 2019 911 Carrera S and headed to a local tuning shop to strap it onto a dyno and see what it’s capable of.

Porsche claims the car’s 3.0-liter twin-turbocharged flat-six pumps out 443 HP and 390 lb-ft (528 Nm) of torque. Judging by the numbers churned out by the dyno, those figures appear rather conservative.

The publication reports that the new 911 Carrera S produced an average of 414 HP and 406 lb-ft (550 Nm) at the wheels during multiple runs. Taking into account a possible drivetrain loss of 15 per cent, that could mean the Carrera S is in fact delivering around 476 HP and 467 lb-ft (633 Nm) at the crankshaft, but it is hard to determine the exact drivetrain loss of a particular car.

In the not too distant future, Porsche will release a number of new 911 variants that will slot above the Carrera S in its range. We know that a new GT3 is just around the corner, but before it is unveiled, we will probably see the car manufacturer release the new Turbo and Turbo S. Sources tell us they will use an updated version of Porsche’s 3.8-liter twin-turbo flat-six, with over 600 HP for the “base” version and up to 650 HP for the S.

    The stock 911 is faster than the old Turbo at 3 second to 60, wonder what the the Turbo version will hit.

  • Kagan

    Well first you don’t know maths. With your assumption it would make 487 hp!

    Second maybe it has much less drivetrain loss.

    Third, you don’t know how to measure.

      I’m interested in your maths.


    they had to do these because turbo will make into production

  • SteersUright

    Did anyone consider that drivetrain loss might be significantly less with these newer transmissions?

    • Especially with Porsche, they are squeezing every bit of efficiency they can.

  • Nastinupe1911

    Yeah… the question will be, which Porsche will they use for the comparison? If they use the Base 911 then it will get spanked in the performance department, but the 911 S or GTS will be another story.
