I don't think Porsche, as a company understands as time change the market change, people change, standard/benchmark change. What was good enough improvement in the old days (5 to 30 HP gain with added weight) may not be good enough in today's market?

As Porsche has never been a HP leader may be ok for yesterday's buyer but may or may not be acceptable for today's buyer. Even if being a HP leader is not a must for sports car buyer today. But I'm sure by offering the smallest of HP in its class is not going to be Attractive either.
