These changed body panels include wider fenders of course, and many of the pieces are made from carbon fiber rather than metal, but there are also some more unusual tweaks. For instance, the headlights actually had to be moved to a different position to make space for the Project 8's massive wheels and tires. The tires, for reference, are 265-mm wide at the front, and the rears are 305-mm wide.
There were also some changes for style. The air vents at the front that consist of many small holes in the bumper are a tribute to Jaguars of the past. The hexagonal shape of the holes apes that of the vintage Jaguar logo, which featured the word Jaguar in an elongated hexagon.
All in all, there's an impressive amount of new engineering that went into creating the Project 8. The results are, in a word, stunning.
