Explore supercar engineering with the LEGO Technic Koenigsegg Sadair’s Spear Megacar 42232, a detailed 4,104-piece building project for adults aged 18 and over. Assemble the V8 piston engine and discover the workings of the nine-speed gearbox with paddle shifters. Front and rear triplex suspension and working steering bring extra mechanical detail to this collectible model. Lift the rear clam to activate Ghost Mode, opening the doors and front hood while the side mirrors fold in one coordinated movement. You can also open the doors and front hood independently when the rear clam is closed. Measuring over 59 cm long, the finished megacar makes an impressive display for vehicle enthusiasts. The LEGO Builder app provides digital 3D instructions with zoom, rotation and progress-tracking tools. This rewarding construction set is a thoughtful gift for adult car fans who enjoy building and exploring intricate mechanisms.
