Porsche's GENIUS New Turbo Design

Turbos are great.
They can make a car quicker, more economical and they even make cool noises.
Perfect, right?
Well, they’re definitely not without they’re pitfalls, and that’s why Porsche have cut theirs in half!

⭕ Why this Wing Won’t Catch On

⭕ Why New Cars are EASIER to Steal

Before we get into that, let’s have a recap on how a traditional turbocharger works.
To quote a certain fuzzy haired car journalist “exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster”.
So what is this witchcraft?
A turbocharger’s purpose is to force air into the engine, hence the term ‘forced induction’. Inside a turbo are two impellers connected by a shaft, one is known as the ‘hot side’ which takes exhaust gases from the engine in order to rotate. As they’re connected, the compressor side, also known as the cold side, spins as well, drawing in air and compressing it.

Would you want one of these on your car?? The seem pretty cool! *Don't forget to subscribe!*

Combine it with a hybrid system, and you could keep the thing at full boost literally 100% of the time while in race mode, and in eco mode, it could keep the compressor off and utilize some of the exhaust gas energy to drive the hybrid system slightly more efficiently

[igamehard]

Feel it's worth mentioning as this is a Porsche video. Porsches anti lag doesn't work the way you described, they leave the intake slightly open when you lift off throttle to keep the turbos spinning

[mollymarsgal]

An electric-driven turbo is similar to Rocketlab's Rutherford rocket engine, which uses an electric motor to drive the turbopump.

We should all get behind Porsche for everything they’re doing to keep ICE alive

Me: "Sitting in my 2002 grand voyager 2.4l and thinking about adding turbo to it" 🙈🤣

[slapmynutz]

I swear Merc had an idea really similar to this that they applied to their 2014-present f1 engines.

[repapeti]

The first thing that comes to mind when hearing "electric turbo" is cheap ebay computer fans that barely move air, leafblowers from Mighty Car Mods and Hoonigan with their "Homemade Quad Turdo Setup".

[privatesector]

I came up with this idea 30 years ago and they laughed at me...

And yet here it is and nobody's laughing now...

Smashing vid. I must admit, I do miss turbo lag, it’s brutally enjoyable. Saab’s come to mind 🤣.

I believe a wastegate will no longer needed as if the car has a 48 volt system, the excessive power from the turbi-generator would be just transfered to the battery.

Now new 911 (992.2) is released. They used exactly the same technology as defined here. Well done with your video. No clickbait.

[Vamanos]

I miss the Volvo inline 5 and 6 cyl capable of running 87 octane per manufacturer unless towing (all of them typically rated to 3500lbs tow cap.)

[vytautassimonis]

maybe it is just me but i like feeling the turbo spool up that makes the car so much more fun on the street

[Gnerko]

Wonder if this could/is also used to increase fuel efficiency. The compressor side of the turbo could be activated upon full opening of the throttle, such that during partial load the turbo isn’t forcing air through a partially opened throttle valve, which normally leads to increased pumping losses. The gas pedal then becomes sort of a pressure regulator for the intake, with the computers regulating throttle position and turbo activation; more gas = more intake pressure.

[corporalpunishment]

I think this video miss represents the fundamentals of Porsche's design. This is not a turbocharger it is a power recovery turbine paired with a electrically driven centrifugal supercharger effectively a turbo compound engine. This engine will ultimately be paired with a hybrid powertrain to make use of the power generated by the turbines. Similar in concept to the 1950s aircraft engine the wright R3350 turbo compound except it replaces the fluid couplings with a generator and a mechanical supercharger for a electric one. This concept could potentially double the thermal efficiency of the engine.

[RuohongZhao]

New Volvo T8 power train used something similar, use the regen electricity to power the electric turbo. But that system may be more energy saving driving but not performance enhance driving.

[HDAspen]

This is why I love Porsche, they really are trying to save the internal combustion engine

[alwinrichaards]

Mercedes also uses this system for a few years, but its 48V, love the evo...

[stefanweilhartner]

it would make sense to use it in a 48V hybrid system.
you could always regenerate more electric energy from the exhaust gases.
so, if you have more energy in the battery, you can use more of that directly with a motor/generator on the drive train.
