It's been described by the best-known names in the business as the best supercar ever made. Top Gear's Richard Hammond, for example, stated that the car is so unreal "it may be a unicorn." And yet the Pagani Huayra is cannot (yet) legally be driven in the United States. A new report coming from CNBC claims that despite Pagani receiving 18 orders for the car in the US, the National Highway Traffic Safety Administration has yet certify the Huayra as street-legal.

Up until now, Pagani has sold 105 Huayras worldwide but is only producing around 40 a year. But despite the waitlist, wealthy US supercar collectors are more than willing to pay nearly $1.6 million for something that's not even fully legal in the US. So why the long delay? Pagani claims it's simply a formality and that the car has already passed the necessary tests. Approval, according to the Italian boutique supercar-maker, should come sometime in March. That would make it the first Pagani certified for the US, the previous Zonda having been kept away. Once it gets the rubber stamp, the first US Huayra should be delivered in July.
