Bonet i Dalmau was an early Spanish automotive venture based in Barcelona, associated with Francesc Bonet i Dalmau, the owner of a well-known textile company in the city.
The marque was notable for producing what is considered the first Spanish car, a three-wheeled vehicle with a single wheel at the rear, powered by a single-cylinder Daimler engine producing only one horsepower. The vehicle was too light to be practical, but it represented a pioneering effort within the country's early automotive history.
Following this initial attempt, Bonet i Dalmau went on to design a four-wheeled vehicle. However, the project was ultimately abandoned due to unresolved technical problems with the differential, and the venture did not progress into further vehicle production.
