World’s Smallest V-12 Engine That Can Literally Fit In Your Hand


For the motor heads out there who think that only gigantic V-12’s are possible, prepare to be amazed. A Spanish engineer, José Manuel Hermo Barreiro, has spent more than 1200 hours in creating the world’s smallest V-12 engine. Designed and crafted by the engineer himself, the 12 cc engine runs on compressed air (o.1 kg/ sq. cm). Patelo has already said that he did not build the engine for commercial purposes, but that it is meant for educational use. He has dedicated the model to his four grandchildren. As small as this engine may be, it carries a big lesson: nothing is impossible.
