Calling all curious tinkerers and future mechanics! Build a race car from the inside out, one satisfying snap at a time, and discover what makes those wheels go.

• Explore a visible V8 engine with crankshaft, pistons, and exhaust fan; a working four-speed manual transmission with reverse and neutral; a drive wheel torque differential; shock-absorbing suspension; and adjustable left- or right-hand steering.
• A 40-page, full-color manual guides the build and introduces gears, engines, and mechanical engineering. Requires 2 AAA batteries, not included.
