Nothing but the rumors yet...
Last time unofficial sources talk more and more about future Ferrari SUV, which is, they say, to appear at 2010 Geneva Motor Show. Ferrari FS599 Fuoristrada, as they call it, will be built using the Porsche Cayenne/VW Touareg platform. Of course, no one has even estimate technical data for a car, but some say that the SUV will have Fiorano's engine, which will pull the 2,2-ton car to 100km/h in less than 5 seconds with its 600 Nm. Maximum speed would achieve 300 km/h. As for a price - not less than EU250,000.
P.S. Pics, as I can judge, are derived from Cayenne.
As for me, I think it's one of the worst things to come if they will develop the car, especially based on Touareg/Cayenne. At least, they have never built tractors, what I can't say for Porsche and Lamborghini
