The 4,480 cc engine delivered and was said to be capable of going from in top gear and to rev to 5,000 rpm. The car was exhibited at the 1939 New York Motor Show: "The highest price car in the show this year is tagged $8,900. It is a Lagonda, known as the "Rapide" model, imported from England. The power plant is a twelve-cylinder V engine developing 200 horsepower."
