sonic racer

A typical Sonic slot car race set is sold as a complete kit and usually includes two slot cars, two controllers, a lap counter, guardrails, about 16 track pieces, plus stickers and signage so you can set up races right away.

Slot car sets commonly include about 16 track pieces—roughly eight feet of track—and support multiple layouts, such as figure‑8 configurations and other looped designs that can be assembled in different shapes.

Most slot car race sets are battery powered. Listings reference AA and C alkaline batteries—one set specifies a requirement of four AA batteries—and batteries are typically not included.
