    Solar panel on the roof

    Sure thing.

    Solar panel on the roof

    Aptera has attracted a lot of concern-trolls and ankle-biters in various forums... I prefer to wait and see what happens... but you do you.

    Solar panel on the roof

    The original owners of Aptera were kind of forced out when the company existed in the past. They bought the rights back and started up again with a new and updated design that is miles beyond the old one, and have kept control of their company this time.... not at all the same thing as being in...

    Solar panel on the roof

    I believe Tesla would have to cover their rear window with solar to come anywhere near close to the square footage available on the Aptera... which covers not only the dash, roof, and hood, but the entire rear hatch.. a stretched out and fairly large area on the car. Thanks for not ignoring the...

    Solar panel on the roof

    It does not need a great number of buyers... only 6,000 per year to start seeing a profit and they have over 47,000 reservations so far... once they are on the road, they will get plenty of interest as a completely unique vehicle. It does not have to appeal to a mass audience, and does not have...

    Solar panel on the roof

    Aptera is said to have 34 square feet of solar panels which is about right for 700 watts. You have indeed ignored the stated efficiency of the vehicle so as to dismiss the solar harvest being of any use... as if it were like any other car.. cars which would indeed not see much use for solar...

    Solar panel on the roof

    As I said, even if it is only 1/4 of what they claim, that is still ten miles a day parked in the sun... not a gimmick, but just one of the many unique features of the vehicle. I don't expect their advertised numbers to be accurate (anymore than any other advertising), except perhaps under some...

    Solar panel on the roof

    You may have missed part of my point... it's the low coefficient of drag of the Aptera vehicle itself that makes a small solar yield a viable and worthwhile effort. As I mentioned, even if the yield is much smaller than the stated optimal, it will still make a difference with such an efficient...

    Solar panel on the roof

    You are mostly correct... however, it is the coefficient of drag as well as weight that limits how useful solar on a vehicle can be. You should look into the reborn company of Aptera. They are past the prototype stage and are starting production intent builds for crash testing etc. The initial...

    Charging 80 or 100%

    I have always charged my 60 ah i3 to 100% whenever possible, and it often sits with a full battery for 3 or 4 days to a week at a time. Seven years I've been doing this... also plenty of DC fast charging. Not even a hint of range loss after 102,000 miles. It should be obvious that when you have...

    Windows open ?

    You have inadvertently pressed a button on the remote. Long press opens the windows. This is a silly feature that is nice on hot days, but can get your i3 water logged if it is raining.

    Scary catastrophic tire failure (not on an i3)

    I bet that tire was way over-inflated.

    [i3 BEV] Drivetrain error

    Not an expert, but was this vehicle in a crash? The high voltage connection to the traction battery may have been disabled as a safety feature immediately after a crash. You may have to visit an independent BMW repair shop and ask them for help diagnosing the error codes... they MIGHT have the...

    Carrying Cargo 'n Things with Our i3's...

    It was a stack of foam boards and very tiny shower stall... the whole thing weighed under 150 pounds. I used 8 suction cups and multiple straps. Drove it 80 miles on the highway without any safety concerns whatsoever. Hard braking and swerving would not budge it. There was some range...
