Description
About this set
The LEGO Technic Koenigsegg Jesko Absolut Grey Hypercar is an 801-piece model honoring a hypercar that ranks among the fastest you can legally drive on the road. Builders put together a moving V8 engine and a differential, then test the steering with a detachable knob that stows in the nose. The doors use a dihedral synchro-helix system, rotating 90 degrees and swinging outward like the real car’s.
It’s a solid challenge for kids 10 and up who love fast cars and want to see how they work. It also looks sharp on display. With the set retiring, new sealed copies will get harder to find.
Highlights
- Moving V8 engine and a differential
- Steering with a detachable knob up front
- Dihedral synchro-helix doors that rotate 90 degrees
