A Ferrari FXX K Evo has recently come to the Mugello Circuit for a test run of its roaring V12; hit Play to see and hear it in action.

The FXX K Evo is a lightweight modification of the standard FXX K, complete with enhanced aerodynamics and downforce. Both are derivatives of the LaFerrari model and inherit its 6.3-liter twelve-cylinder in conjunction with an electric motors and KERS system. The cumulative output amounts to 1,050 PS (1,036 hp / 772 kW) and 900 Nm (664 lb-ft) of torque.

The standard FXX K came out seven years ago in a run limited to 40 units. The Evo hit the track three years later and was available as a ready-made car and a conversion kit. Ferrari did not reveal the production quantity for it.

A year and a half ago, a 2015 Ferrari FXX K coupe with 250 km (155 miles) under its belt sold for U.S. $4.3 million at an auction, nearly 1.5 times as much as it cost when new.

The XX vehicle range has been in production since mid-2000s. The company uses road-legal Ferrari chasses for it, and treats buyers to closed track day events on famous circuits.
