If there is enough space, the Hispano Suiza must be able to reach a top speed of 225 kilometers per hour.Leno’s aero car is also equipped with a horn that must have been lifted from a locomotive, so Californians know when to get out of the way.

As usual, three quarters of the video consists of a technical analysis and some background information, only in the last five minutes of the video we see the car in action. For the lovers of pre-war monsters with aircraft engines , this is highly recommended.
