Jay shows us what it's like to drive a World War I aircraft on the street with his 1915 Hispano Suiza that features an 18.5-liter airplane motor.

      Man, am I ever looking forward to this !  That engine was the absolute pinnacle of engine technology ... it would be 50 years before many of its features became avaialable in consumer autos and 70 before they became common !  towit : OHC, Aluminum Block with replaceable liners, Aluminum head, we still don't see dual ignition in stock autos, despite the advantages.   It SURE IS like an airplane in the cockpit.  !!  What a freakin' trip !

      Local folks on the freeway know it’s Jay from a long distance back. It’s the only way a car that old, that big can be going that fast. Gotta be a Jay restomod !!
      OK, maybe the flying silver hair is a clue.

      Nope, sorry Jay. Antoinette had a V8 aircraft engine in 1907. And, more or less the same engine was used in a car the year before, and the basic root of that engine was patented in 1902. The Hisso could be called the first really reliable V8 aircraft engine, though.

      Jay....if you're ever in northeast PA we have several airplanes with this motor. Eagles mere air and auto museum. Fuel pumps on these are propeller driven off of the main prop.....ours are rated at 180hp (non-turbo)....

      A machine gun? Well, OK I guess. A Lewis gun literally clamped to the edge of the basket / cockpit! No shoot through the prop, the Germans did that with the Eindecker. The SE5 was an anachronism even in WW1!

      I'm pretty sure Wolseley built that engine for the RAF SE5, probably under licence. If memory serves me correct, it was called the Wolseley Viper in that guise. As for 300HP: I worked at the now defunct Royal Aircraft Establishment (defunct thanks to Thatcher). A SE5 was restored to flying condition there and the prop was tested on the prop spinning tower. It would absorb 200HP at 2000 Rev. The Viper engine could turn it as 2000 Rev but I think not more.

      Jay I was wondering. Is that the same shirt you bought before you moved to LA from NYC? WE both have silver hair now. That Sunbeam was junk.

      Hello Jay, I can understand why you say this is one of your favorite cars to drive. There are not too many people out there that have the understanding, I know I wouldn't have. It like you said you almost have to be a pilot.
      This was a good video for me. I just started watching your youtube channel recently. I am very happy for you that this gig is working out for you. Your old show changed and its better that you left. It'll never be the same. Please keep making this show.

      The guys who ran Hisso's in Sprint cars must had some balls... I had a discussion with an employer at a resto shop once about Wolseley Engines,which were OHC and used designs taken from the Hispano Aero engines, but as Morris came on the scene they also made OHC engines using wolseley Designs in the Morris big Sixes and the little minor. Before they made a minor with a sidevalve. As result some of the MG's had an OHC engine too. He couldn't understand that Wolseley engines had their design based on a WW1 Hispano.

      All those people who live or work within a few miles of Jay's place are a very fortunate bunch. Seeing his cars and bikes go by every week must be an awesome sight to behold, especially when he's driving a car like this.

      Brought to mind by Jay's comment about how much better modern oils are: A lot of WWI-era aero engines (not this kind--the rotary ones, like the Gnome) were originally designed to be lubricated with castor oil. Since those engines had total-loss lubrication systems, pilots of rotary-powered aircraft with the engine at the front would get a lot of the oil thrown back in their faces in flight. Inevitably, they'd end up eating quite a bit of it, with... predictable results. Oh, for the glamorous life of a dashing Great War airman. All that and a two-hour life expectancy too.

      Hey Jay,….I think your camera vehicle needs a tune up. Looked a big cloud of carbon coming out the back of it when you started out on the highway entrance.

      At 16:05 Jay should have pulled up along that white Rolls Royce and started freaking like he was just bowled over seeing a Rolls. Oh yeah, that's right. Its L.A. Nothing special about Rolls spotting. Takes something really odd to turn the heads of the jaded. Like a car with an aeroplane powerplant.
