Non-electronic LEGO vehicle sets include working steering and mechanical controls using gear elements and linkages that let builders steer or move parts such as loaders, doors and other movable components.
Some vehicle- and ship-style sets add electronic modules and chargers to provide powered motion, motion-activated sounds and lights, while other sets provide powered play through mechanical systems (gears, loaders, steering linkages and spring-loaded elements) and list no required battery.
Interactive sets use a small electronic module plus smart tags that trigger motion-activated engine sounds, lights and other effects in response to how the set is moved or played.
Some kits include a packaged lithium‑ion battery and a charger for the interactive module. Many vehicle-style sets list no battery and rely instead on mechanical play features.
Mechanical vehicle sets focus on physical functions—gears for steering, loaders for grabbing/lifting/tipping, and spinning or spring-loaded elements. Interactive electronic sets add a module and smart tags that produce motion-triggered sounds, lights and other electronic effects.
Smart tags activate the interactive module to trigger dynamic sounds and lights based on how the set is moved or played.
