Build and race your own LEGO Technic Ford Mustang Shelby GT500 (Set 42138), an authentic 544-piece model replica of one of the most iconic American muscle cars. Designed for builders aged 9 and up, this set faithfully captures the bold lines and aggressive stance of the real Ford Mustang Shelby GT500 drag race car.

The completed model features two pull-back motors that store kinetic energy — simply pull back and release the trigger to send the car speeding across the floor. A detachable rear cover lets you switch between play mode and a sleek display configuration, making it equally impressive on a shelf or in action. The set measures approximately 27 x 12 x 8 cm (10⅝" x 4¾" x 3⅛") when complete.

Compatible with the free LEGO Technic AR app, this set unlocks an augmented reality experience where builders can take on the role of a drag race driver, test their car on a virtual racetrack, and complete in-app challenges. The app enhances the building experience with interactive AR features tied directly to the physical model.
