Inspire kids to build their own model race car with the LEGO Technic Koenigsegg Jesko Absolut Grey Hypercar building toy for 10-plus-year-old boys and girls (42173). A rewarding challenge awaits kids who love buildable model car toys as they assemble all the details. The build is just the start! This race car 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 of the LEGO vehicle by using the detachable knob that fits inside the front of the car. A cool feature of this vehicle toy 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 model car set makes a great gift idea for kids, boys and girls aged 10+ who love vehicles. It comes with the LEGO Builder app, which lets builders zoom in and rotate models in 3D.
