Known by the internal code M4630, the 3.0 litre V6 bi-turbo motor in the Macan S is a derivative of the M4660 motor first seen in the face-lifted Panamera last year, but with Macan-specific air-intake system and cylinder heads.
That said, for long-term reliability as well as product differentiation, Porsche decided that the Turbo model should start life with a bigger engine. As 3.6 litres is a familiar displacement in the Porsche 911 flat-six engine family, it is no coincidence that the Macan V6 Turbo motor should also share these iconic numbers. With its longer throw crank and connecting rods, the 3,604cc M4635 engine derivative has a bore and stroke of 96.0 x 83.0mm, and ends up with exactly 4.0 cc more than the iconic 3,600cc 911 flat-six.
What about the '18 model Turbo? I had heard that this was the last year(?) that Porsche used a Porsche engine? After that, they switched to all Audi blocks? Education needed please.
The engineers sit near each other and use the same design manuals. One engine gets more goodies and spicier tuning than others and carries a higher internal manufacturing cost and is installed in a vehicle with a higher selling price.

That's true.
but honestly I would worry a lot more about the PDK than the engine, besides the TCC leak there really isn't any widespread failure of the M463X.

What's funny is if you Google 'EA837 Macan' nearly all of the results that come up are from this user spreading fud on forums like this.
Why is the last item in this table a Macan Turbo when the Turbo doesn't exist since the latest ICE refresh? And the numbers for the current GTS are not correct (they are essentially what the old Turbo was)

There's a little bit of confusion with model years in this table, and it looks like they may be using UK style model years (IE purchase year and not design year). There technically was a 2021 Turbo (design model year) but of course the GTS became the top dog in 2022 and got Turbo level power (same engine, just different tuning).

From Bimmerpost.com:
The EA839 is not the same in the Macan, it's in the S4, SQ5 etc and has ring failures it seems. I'm not sure if the forged bottom end in the 2.9L variant has these issues, but there are serious issues with the S4/SQ5 platform. I have a buddy who dropped cylinder 4 and 5 just recently. Tuned ones have a tendency to drop #6. Call any local audi shop and ask them what they think of the EA839.
