The 40HP was a luxury car produced between 1907 and 1909 by the Spanish automaker Hispano-Suiza.
The 40HP was launched at the end of 1907 at the Salon in Paris. A year before the orders were open, the first of these cars was ordered by the then King of Spain, King Alfonso XIII. He was a car enthusiast and a great admirer of Hispano-Suiza.
The cars were fitted with a four-cylinder in-line engine which had a capacity of 7433 cm³. The car had competition such as the Renault 35CV, Peugeot Type 113 and Panhard & Levassor 35CV. The performance of the car was good, considering that it could reach 100 km/h when fully loaded.
The production of the car was ended in 1909.
