The link shows the cars released fo far. While they all seem to have the hump except mcclaren thefront wings designs are a thing of beauty on some cars. Cant help thinking that the lower front designed not to take a drivers head off in a side collision, on some cars its so thin it looks like it would slice into the cockpit like a hot knife through butter.
