Ferrari already confirmed directly to Autoblog that the XX is under development. There are even spy photos of it testing at the Nürburgring (pictured above). It reportedly clocked an astonishingly fast six-minute, 35-second lap at the historic track. The latest scuttlebutt about the track-focused supercar, according to Top Gear, is that it ditches standard car's hybrid 6.3-liter V12 engine with a combined output of 949 horsepower and 663 pound-feet of torque in favor of a Formula One-derived V6 turbo hybrid. That would be a huge change but would likely cut weight. The more insane LaFerrari could debut as soon as January or February of next year.
Ferrari says it's difficult to make the XX accelerate much quicker than a standard LaFerrari, but slick tires, revised suspension and aero changes should cut lap times. A version that doesn't have to worry about road car laws and just focuses on being fast could be truly mental.
