From Toyota Wiki

The Daihatsu Costa was a Concept car introduced at the 2005 Tokyo Motor Show. It is basically a City car designed to be taken to the beach.

The Costa is a light, weighing only 1,654 pounds (750 kg). It has no doors, similar to a Golf cart. It is powered by a 660 cc Turbocharger 3-cylinder engine. Its light weight and comparatively powerful engine make it relatively fast for its size.

There are no plans to bring the Costa into production.
