Bilar We proudly present the World's Smallest Running Car! Nippendenso (Japan Electric) developed this Micro Car. At 4.78mm (yes, milli-meter), it's about the size of a grain of rice. A 1/1000-scale replica of the 1936 Toyota Model AA sedan, the front-wheel-drive Micro Car is powered by a three-volt 0.67mm electric motor (more power, arghh..argh.argh) with just five moving parts! The motor includes a coil that uses 1,000 turns of wire. Wow, or better yet, Whoah!
