Apart from the obvious fact that it's so damn fast.
The Lamborghini Aventador SV is obviously a pretty outrageous looking car, but what with the regular Aventador being so outrageous, it may not be obvious in which ways the new version has been changed. So here we have Filippo Perini, head of design at Lamborghini, talking about the SV and what has been done to change the styling. It is slightly unfortunate that pretty much all of these changes have had to do with weight or aerodynamics, and not because they look good.
But such is the current state of supercar design, where cars have become so fast that even the Italians can't make things solely on the strength that they're beautiful.
