    I thought I would share this. The story behind the company and president has many sides (crook, fraud, killed by big oil, etc.) but still worth sharing.

    My childhood dream car. I saved up my money and talked with the manufacturer (see hand-written notes on last page).

    It never went into production.

    All of its promises are now fulfilled with my Tesla Model S- VIN 4265.

    Wow, very interesting, thanks so much for sharing! When I was a kid growing up in California in the 70's, this was exactly the kind of car we kept hearing about...But then had to wait almost 40 more years to see become a reality!

    Incidentally, Is it just me, or does the front of the EXAR-1 strongly resemble the wedge-shaped nose of the iconic Lamborghini Countach? A.K.A. The first car I ever fell in love with...

    Good catch!, But I think the car was based on the Lamborghini Espada:

    I find it interesting that the Range is 75-100 miles. Not much has happened since then (except Tesla). All other manufacturers have the same Range.

    Couldnt work out how many kWh the battery is? Should compare efficiency and weight against the Leaf. 125-180 mpge?

    Does that REALLY say 19 hp? Mother of god.

    Edit: Crude calculation with that curb weight says 0-60 in 40 seconds.

    100 mile range is probably using very optimistic assumptions (plus you have to keep in mind the EPA testing has changed to much stricter standards now).

    Article only mentions 144V 1600lbs of lead acid batteries. Article claims 5 hours for 220V charge (40 amps peak) and 8 hours for 110V. 110V even at 15A peak only gives 12kWh of energy.

    By comparison, the 1996 lead acid EV-1 had 1200lbs of lead acid batteries with 16.5kWh (312V, 53Ah) of energy.
    http://avt.inel.gov/pdf/fsev/eva/genmot.pdf

    If they are assuming 125mpge for 75 miles of range and 180 mpge for 100 miles of range, that means they have about 0.6 gallons of energy, which works out to 20kWh if you use the 33.7kWh per gallon conversion (they may be using a different one).

    So pretty much no more than 20kWh, probably in the 10-15kWh range.

    Like most DC motors, that's probably the continuous power, peak power is probably 2-3x that, or about 40-60hp.

    great post.

    1600lbs of lead acid batteries and a 19hp motor. oof.

    looks pretty deloreanesque (although some years before, yes?) to me, but def seems based on that espada, which is gorgeous. never saw that before.

    thx all.
