Set 40894 recreates the steering wheel from the Koenigsegg Sadair's Spear hypercar as a 228-piece Technic building experience for adults. The model includes working features that mirror the real vehicle, with a speedometer that stays level as the wheel turns and a gear indicator that responds to the pedal shift. A printed logo tile at the center of the wheel adds an authentic finishing touch, making it a polished display piece for a desk or shelf. At just under six inches deep, the completed model has a compact but substantial presence that suits fans of automotive engineering and supercar design. It works well as a gift for adult builders who appreciate detailed mechanical projects tied to real-world vehicles.
