The first generation of Porsche 911 debuts in 1963. So, the 911 model of Porsche is 58 years old, and still is one of most popular cars in the world.
Porsche first joined the flat-engine fray when Ferry Porsche put a VW Beetle 1.1 litres, four-cylinder engine into his Porsche 356. The air-cooled flat engine was also an ideal choice for sports cars such as the Porsche 911 as its low design lowered the car’s centre of gravity, giving a sportier and more dynamic style of driving. Unlike today’s modern water-cooled engines which are closed circuit, the air-cooled engine released engine heat directly into the air. Air-cooling reigned supreme up until the introduction of the Porsche 911 996 in 1998. This makes the Porsche 911 993, produced from 1994-1998, the very last of the air-cooled 911s.
With the type 996 – Porsche took the bold step to stop using air-cooled engines. The flat engine design was preserved – but the cooling changes. A newly developed water cooling system is presented in type 996. It becomes the first 911 with water-cooled flat engine.
Porsche 996 is an internal design of model 911. It is manufactured in the period between 1997 and 2006. In 2004 is presented the 997, which later replaced 996.
