Inspire boys and girls aged 10+ 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 kid ... s who love buildable model car toys as they assemble all the details. And the build is just the start! This 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 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 801-piece set car makes a great gift idea for kids who love vehicles.
