It was amazement at the IAA Frankfurt Motor Show just 25 years ago. The new 911, generation 996, abandoned its traditional air-cooled engine in favor of a liquid-cooled block (still 6-cylinder flat). Purists cried foul, for fear that this engine would no longer sound like a Porsche should sound.
Close to the Boxster
But there was something else. For the first time, this 911 shared a large number of parts with another model: the Boxster, with a completely identical interior. The front end of the 996 was also very similar to that of the Boxster. Explanation, Porsche was not doing very well at the time, and production costs had to be limited. Bet won, since this generation of 911 was a solid commercial success, with more than 30,000 copies sold each year of production.
