Although there are plenty of people who have a definite favorite, it would be genuinely difficult for us to say whether we prefer the Pagani Zonda or the Huayra. They'd be more art than vehicle if it weren't for the fact they're so balls-out fast. So for those who can't pick a favorite, we have the following video of examples of both cars on a track together. The video was made by Miller Motorcars of Greenwich, Connecticut, one of the first US dealerships to get a Huayra.
So you can think of this as an ad if you want, but it's really just a great video of some great cars.
