Aston Martin has a V12 correct, which is quite close in terms of design to the Jaguar V12 that used for practically forever. However putting a V12 in a modern Jaguar would be crazy due to the fact that there are UNIBODY cars. The old ones wighed a ton, well 3 to be exact due to the fact that they were all steel SEMIMONOCOQUE. which could support the tourqe produced by the V12 a few times over. The unibody just wouldn't handle it, it would have to be beefed up to the fact that even with the added horsepower of 4 cylinders it would perform the same. Add to that the fact that Ford has said NO to the V12.
