Build and display the LEGO Technic Koenigsegg Jesko. Features sleek black and gray design with orange accents. Inspire boys and girls ages 10 and up to build their own luxury hypercar toy with the LEGO Technic Koenigsegg Jesko Absolut Grey Hypercar building set for kids (42173). A rewarding challenge awaits kids who love buildable model sports car toys as they assemble all the details. And the build is just the start! This car building toy pays tribute to one of the fastest road-legal hypercars in the world and comes packed with features for car enthusiasts to discover. Young builders can explore engineering concepts as they build the moving V8 engine and differential. Then they can test the steering using the detachable knob that fits inside the front of the car. A cool feature of this racing car for kids is the dihedral synchro-helix door system which allows the doors to rotate 90 degrees and move outwards, just like those on the real hypercar. This LEGO Technic sport car toy makes a great gift idea for kids who love vehicles. It comes with the LEGO Builder app, which lets builders zoom in and rotate models in 3D. Contains 801 pieces.
