Ferrari F70 Enzo test mule

The arrival of any new Ferrari is bound to be anticipated eagerly by legions of fans around the world, but few more keenly than the successor to the famed Enzo.

Following in a line that dates back to the 288 GTO, through the F40, the F50 and most recently the Enzo, the new top-of-the-line hypercar from Maranello is now well on the road to readiness. We're told to expect its arrival in less than a year from now at the 2013 Geneva Motor Show, but while endless speculation has filled the void until now, we've now got our first batch of spy shots showing – to some extent, anyway – what Ferrari is working on.

While the widened 458 test mule in these spy shots is wearing a hideously humorous hodgepodge of sheetmetal and body cladding evidently thrown together in a back room in Maranello (with the lights off), we're told this is not an actual prototype for the Enzo successor – sure to wear a different name, but referred to internally as project F70 – but rather a rolling test bed for components that will make up the finished product.

That is expected to include an uprated (and backwards-turned) version of Ferrari's new 6.2-liter V12 from the F12 Berlinetta, producing more power and augmented by a hybrid electric assist. Despite the added hybrid bigs, the F70 is still said to be light in weight, and it will be sent gunning for the Bugatti Veyron with a targeted 0-60 run in under 2.5 seconds and a top speed in excess of 250 mph.
