### Instruction:
How many parts were brand new in the Porsche 993?

### Input:
The 993 was much improved over and quite different from its predecessor. According to Porsche, every part of the car was designed from the ground up, including the engine[3] and only 20% of its parts were carried over from the previous generation.[4] Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective."[5] Porsche's engineers devised a new light-alloy subframe with coil and wishbone suspension (an all new multi-link system, Weissach axle), putting behind the previous lift-off oversteer[3] and making significant progress with the engine and handling, creating a more civilized car overall and providing an improved driving experience.[4] The 993 was also the first 911 to receive a six speed transmission.[6]
