If you look at it in a different light, it would have been very derogatory for the engineering talents of Porsche if they were not able to improve on a 15+ year engine design and as a result they were forced to keep using it indefinitely.

Other premium manufacturers like BMW and Audi improve and change their engines every year or so that very few take notice.

But like many things Porsche this engine acquired mythical status! It is like the 993 Carrera that many admire and swear to it. I drove one the other day and it felt like a cart(not kart)compared to a Boxster S MkI.

Put everything in the right perspective please!
