Macan S 340 vs 354 engine
Discussion
Hi everyone,
While browsing for a new car, a (used) Macan has become a possible contender.
I'm looking at pre 2018 faclift Macan S and I wondered about the engine.
While I figured out the past 2018 has the VW EA839 2'995 ccm V6 from Audi, I can't seem to find much info about the 2'997 ccm V6 they used before.
A post on a french forum claims it is a Porsche block with Audi heads. Is this correct?
Does anyone have any more infos about this engine?
I did some digging into this a few years ago having had 3 Macans before the 2018 change over to the 2.9 litre Audi sourced unit. Some people thought that the original V6 was a derivative of the old VAG VR6 but that was easily discounted due to the evident difference in the angle of the cylinders between each bank.
What I found was that the original Macan Petrol 3.0 V6 was derived from the V8 Porsche developed for use in the Panamera and Cayenne with 2 cylinders knocked off. I believe that the Turbo Models 3.6 V6 is a further development of the same engine with a longer stroke and possibly other modifications. I didn't dig into the origins of the V8 so that could put a different take on things. The diesel V6 in the Macan is a VAG unit as Porsche did not want to develop their own and of course these were all discontinued anyway after the emissions rigging scandal.
Since the VAG 2.9 V6 had already been successfully developed to reliably produce higher outputs than the Porsche 3.0 and 3.6 units the decision was taken to use these rather than develop the in house units any further. At about the same time a group wide decision was made after VAG went through a review of all the engines in their portfolio that Porsche would develop V8s, Audi would develop V6s and VW would develop 4 and 3 Cylinders obviously saving huge costs across the whole business.
That's about all I know, perhaps others know more.
