Ferrari F70: First Photo

We have what appears to be the first photo of the Enzo replacement - the Ferrari F70 – taken at a private viewing for Ferrari clients in China. Despite expectations that the new Ferrari F70 would be revealed before the end of 2012 – which is what Ferrari boss Luca di Montezemolo told us – we still haven’t had the reveal of the F70 in any form, and certainly not at the Los Angeles Auto show, where we expected Ferrari to debut their new hypercar as it’s the last motor show of note for 2012. It now looks like – short of a non-motor show reveal – that the new F70 will bow in at Detroit in January, but ahead of that it seems Ferrari are already showing the F70 to select clients.
