Please learn the simple formula. You have no clue what is power and what is torque.
P= torque x rpm.
ALWAYS!
So that means power is everything. That’s why formula 1engines rev to 20. 000 rpm.
To explain it simply. You can bring out your torque wrench. The biggest you have and tighten a bolt to 400Nm. Once it’s tight you can have the lever horizontal 1 meter and put 40kg on the end. 400 N.
Nothing moves it can sit there for 1000 years and no work is done. You still have 400Nm on the bolt!
Totally useless. Torque is nothing without movement. Her that is revolutions.
Or to be the right unit. Angle velocity.
1 rpm= 0. 105 radians/ second.
This means simply that power is the product of torque and rotation.
You can rotate a little ball beating 10. 000 rpm and it takes no effort no torque to do it so you have about zero power Watts, kW,
But moving something heavy fast uphill gives both torque and speed. Therefore it’s power.
At last. Just reving your engine without load. Gives very little power, it’s only the friction inside the engine that is torque. So 7500 rpm but just torque enough so it doesn’t stall.
So power is everything. The rest is a gearbox and you can get any torque you want on the wheels. 50 hp 10. 000 Nm is not strange. Just divide the power with the torque and you get the revs.
Remember to use the right units.
Don’t present power torque and revs. It’s all the number in the equation. Take away any and it’s simple math to get it.
Please learn basic physics.

I don't think Porsche have lied. Porsche sells cars all over the world and that means that they're sold in hot countries, cold countries, countries that are at sea level, countries that are at much higher altitude, countries that have dry air, countries that have high humidity etc etc
All of these factors affect the power output of an engine, so every car sold will produce different power outputs based on their location.
I understand that Porsche always quote their power outputs based on being in the conditions that reduce power output the most. This means that, wherever the car is sold, you won't get less than the quoted power figure.
Is that lying or honesty

Fake news.
Porsche are quoting hp at the flywheel, and you’re measuring it at the rear wheels with a correction factor for drivetrain loss. 725 vs. 711 is within the margin or error of whatever was assumed. That’s not accounting for variability due to ambient temps and manufacturing tolerances.
Edit: Unless this is true RWHP in which Porsche are WAY underestimatingbut someone above said the dyno stated 620RWHP.

This can't be a surprise to anyone. Porsche has traditionally understated their horsepower claims and inflated their 0-60 times just slightly. It's a conceit, if you ask me. They can under promise and over deliver and still have better claimed numbers than their rivals. Meaning they don't even have to put their best foot forward to sell their sports cars. Until recently with the catastrophic pricing, that is.

and that’s WHEEL HP. Most manufacturers as we all know use crank to fluff the number. So, crank I’ll get that Porsche is around 868 crank HP and 1, 023 crank torque. Just assuming a 20% reduction in drivetrain efficiency loss, plus or minus dyno efficiencies, conditions, blah blah blah it’s an approx. guess. That’s a lot of hp and torque regardless.

The dyno measures only power to the wheels, not engine power. So the engine power is totally fake and make up number, trying to 'guess' how much drivetrain loss there might be and artificially add that number to the wheel power number. But it is just a guess and some dynos add more, others less.

No. THAT particular car has 724hp. The guaranteed minimum hp is 711hp. In this case its a 2% difference greater. There is always some minute variability even in the very best powertrains.
Amazing powertrain. The electric turbocharger system is a work of art.

I’m pretty sure in Germany or something it’s illegal to sell a car that provides less horsepower than initially claimed. So mostl manufacturers, especially the one selling around or from there actually say they have less horsepower than actual

Probably the only few companies which gives lesser numbers than the actual ones unlike the hyped up ferrari ones which r well known for lying and giving tuned up cars for reviewers and then delivering tuned down cars for customers.

So 725 instead of 711hp That's less than 2%. different dyno or different day will have bigger differences than that. 2% is nothing. And torque is 6% The car is exactly what's advertised. Not sure why Porsche lied about anything.

Despite being owned by VW, Porsche is one brand that I can actually trustwell, not entirely, but I have faith in them as a car lover. It is interesting when carmakers goes conservative with their car's power output, to say the least

Non-touch lcd screen is not supposed to be touched. It causes visible ripples, and can permanently deform or damage the internal layers and pixels. I have some clients who do the same, that's so annoying.

Depends on a lot of things, humidity, temperature and elevation, 700-730hp are the expected numbers, also every dyno reads different, they didn’t lie, they just went conservative to not look like liars

Bit like BMW but pretty sure most manufacturers understate their bhp figures as the engines need to work in a multitude of environments eg: Hotter climates and higher altitude climates with thinner air.

Car manufacturers have to state average figures. It can go up or down depending on ambient temperatures, differences between engines due to manufacturing tolerances, quality of fuel etc etc

Reminds me of TVR. A guesstimate was always good enough as long as the lowest was achieved. Cerbera 4. 2 was quoted as having 350 bhp but many examples have 350 up to 380 bhp.

That's a lot of shouting for 14 additional horsepowers on a high performance engine. On a different dyno the results would be different. It's a magnificent engine though.

Give me naturally aspirated engines any day. May not be as fast turbos/electric but they’re generally more reliable and have a more pleasing exhaust note.

The thing I love about Porsches is that other cars need over 1000hp to do what a 700hp Porsche can do. Porsche is the best at converting hp to performance.
