How many parts were brand new in the Porsche 993?

Context:
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 and only 20% of its parts were carried over from the previous generation. Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective." 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 and making significant progress with the engine and handling, creating a more civilized car overall and providing an improved driving experience. The 993 was also the first 911 to receive a six speed transmission.<|im_end|>
