As a track-only model, the Ferrari FXX K was based on the LaFerrari, pairing a powerful V12 engine with the KERS hybrid system to deliver over 1,000 horsepower. This LEGO Technic set lets you recreate it in brick form. It captures the car's wild aerodynamics, including the dual rear wings, as well as the opening butterfly doors and hood. The signature V12 is on hand, complete with moving pistons, as is a realistic differential. Once built, it measures nearly a foot long, making for a substantial addition to any LEGO collection.
