Pagani Huayra in Purple with Tricolour Calipers (video)

We have video of what looks like a new build Pagani Huayra, still plastic wrapped, in purple with Italian Tricolour brake calipers. That’s because the Pagani Huayra has not, as far as we can tell, managed to get a European Certificate of Conformity or managed to be Federalised for the US, so sales are impossible. But Pagani are still producing a few cars – although they’ve probably built more Zondas in the last two years than Huayras – but it looks like this Huayra – caught on video outside Pagaini’s premises in Modena – is a new build.

Fisker Karma S concept

Fisker Automotive revealed the newest addition to its lineup at NAIAS 2009, exactly a year after the independent carmaker unveiled its first concept vehicle, the Karma. Called the Karma S concept, the four-seat convertible was designed by Henrik Fisker with input from a newly assembled design team taken on to help bring the Karma sedan to production. The design of the S is likely to make it to the showroom almost unchanged.
