Could this be the fastest production car to ever lap the Nurburgring Nordschliefe? According to our spy photographers, yes.
What makes it so special? Well, at first glance, there's little to differentiate this car from the 'regular' LaFerrari that was revealed in Geneva a year ago.
But look a little closer and you'll notice the absence of paint on this LaFerrari's carbon bodywork, as well as the wide-set wing mirrors and rear wing extension. The side glass has also been replaced by lightweight lexan, with sliding panels in lieu of power windows.
And with all 499 production LaFerraris already sold and no race program announced, this is in all likelihood a development mule for the upcoming LaFerrari XX.
Like the Enzo-based Ferrari FXX and 599XX (above), the LaFerrari XX will be non-road-legal development of the LaFerrari road car, with an emphasis on reduced weight, sharper handling, more downforce, better traction electronics and racecar-like dynamics.
But unlike the FXX, the LaFerrari XX is not expected to pack any more horsepower than the 708kW/900Nm+ road car it's based on.
Curiously, Ferrari customers fortunate enough to buy an XX model (and they'll need deep pockets: the FXX sold for roughly £2 million) don't get to keep their car.
Instead, Ferrari only allows them to be driven on selected racetracks at a time of the company's choosing, and data gathered during these events is used by Ferrari's research and development team to design the next generation of Ferraris.
So when will the world's moneyed elite be able to slap down a deposit on the LaFerrari XX? Given Ferrari only offers XX models to its most loyal customers, the odds are high that they'll all be sold long before Ferrari formally announces it.
That said, expect to see it make its public debut at the 2015 Geneva Motor Show.
