Ford's new engine is so small it fits in carry-on luggage

Spirit Airlines would have a field day with this.

Ford’s new 3-cylinder engine is so small it can fit into a piece of carry-on luggage.

At least its aluminum block is.

A team from Ford brought the heart of the smallest engine it makes to the security checkpoint at Detroit Metro airport in a roll-on bag, put it in a tray and ran it through the X-ray machine to demonstrate just how tidy it is.
