Build a fully working V8 race car model that teaches mechanical engineering concepts as you assemble a visible eight‑cylinder V8 engine, a real four‑speed manual transmission with reverse and neutral, a drive‑wheel differential, shock‑absorbing suspension, and adjustable left/right steering; the kit includes 233 pieces and a full‑color 40‑page manual to guide hands‑on STEM learning, requires 2 AAA batteries (sold separately), and is recommended for ages 10+.
