Couldn't pick a winner, all of them have their merits
There is a gravity race here in SoCal that takes place on one of the most treacherous roads with lots of tight corners and big drop offs. It is very interesting as different teams have different approaches: some subscribe to the thin tire/less rolling resistance for speed, while others went for the fat tire, go faster through the corners approach (the Chapman philosophy and which ultimately won)

From Honda (the winner) and the neatest car IMO - Full independent wishbone suspension with inboard coil overs and 4 wheel disc brakes
