    Dear Aptera,

    HOW MUCH do the SMALLER BATTERIES than the top 100 kwh (and thus less weight) IMPROVE these capabilities (which less vehicle weight by definition does):

    1. Max payload weight

    2. Acceleration

    3. Top speed

    4. Miles per kWh

    ?

      @Torsten Freund Aptera staff rarely provide direct input into threads but you can see some of the estimates in this thread. More precise numbers probably won’t be available for quite some time.

        Over on reddit there is a similar thread. I think the consensus is that the smaller battery sizes will probably have have a smaller power output, which pretty much means that we can’t calculate anything meaningful for acceleration until they give us the details. Fingers crossed for tomorrow. There’s only a day to wait (even if that time seems to be going extremely slowly!).

        Thanks for the links, Gabriel and Michael. Good point about power versus acceleration. Aptera themselves said earlier that there will be .2 – .4 seconds “difference” in 0-60 m. between the 25 kwh and 100 kwh. Well, to be seen. Yet, the three other capabilities – max payload weight + top speed + miles per kWh – should still by definition improve with less weight (due to smaller batteries or any other weight reduction for that matter). I would just like them to answer HOW MUCH. Not the TOTAL amount/number, because you can’t really until real world testing, but the DIFFERENCE should be possible to state.

    I assume the web site was very recently updated, but the performance numbers seem to be slipping. The power of the motor, which had been 50KW has been reduced to about 43KW. Also, in a recent podcast, Steve Fambro mentioned that the weight went up a bit due to the change to the skateboard design. Those two things have changed the published 0-60 times to 4 sec for the AWD configuration and 6s for the FWD configuration (from the previous 3.5s and 5.5s respectively).

      I think the reduction in power … the base M700 motor on which the Aptera is based is rated at 70kw and the Aptera motors were originally established at 50kw motors and now, as pointed out, have been further reduced to 43kw.

      This suggests the motors have been physically altered from the ‘standard’ Elaphe motor in this class. I suspect they just dialed back the power by limiting the output of the single motor inverter to keep with the promise of 10mi/kwh economy.

      That McLaren is looking at Elaphe motors/inverters for racing and super-car power tells all of us that there is a long way to go before we reach the penultimate of performance for in-wheel motors.

      This bodes well for future addition of higher-output motors in actual sportier, more-pricey offerings from Aptera.

        If what you say is true then I see inverter swaps being very popular. I too was looking forward to having a sub 4sec 0-60 vehicle. I like the efficiency, but lets face it I’d give up a bit to get back the 3.5sec 0-60 previously advertised, as this is to be my sports car substitute. Especially now that DCFC has been confirmed and will be more than adequate. This is of course assuming the limit will not be the current draw on the 400mile battery pack for the LE, in which case that will be the hard limit for acceleration, with no mods in sight.

        Eve 50e cells are rated for 3c (full discharge in 20 minutes). The motors are likely not the limiting factor – the cells are. High end cells like those in the model s plaid can handle 7.5c pulse discharge but typical commodity cells can’t. They have no burst rating and 3c with this pack will limit output. The 66kwh will achieve full power and likely be a little faster despite more weight.

    Whether you guys decided to buy in because of the advertised 3.5 0-60, or if it’s irrelevant to you, it was a major part of the draw of Aptera for me. A half second loss on the 0-60 is big, now it’ll just keep up with gas guzzlers, I was excited for a Solar car that would leave them behind. Fast charging is something that can be added easier than acceleration can on an electric car. I’m sure there will be no option for making it faster that doesn’t void the warranty.

    I get from a usability standpoint DCFC is a bigger deal to most people, but I was all in on that acceleration, and my enthusiasm is significantly dampened. I’m not interested in arguments that 4.0 is fast enough blah blah blah, they should have been more conservative in their earlier advertising if they couldn’t actually hit that number. Acceleration scale is exponential, not logarithmic, half a second may not sound like much, but it’s a BIG gap if you actually care about the acceleration, which I massively do.

    Aptera has a lot of draw backs, which to me were more than made up for by solar charging and fantastic acceleration. Now… Other options are starting to be more attractive, if I’m not getting the speed why make the sacrifice in size and passenger carrying?

    What do we think? Will there be any sort of go fast modifications short of drivetrain replacement that can make the car faster? Or are we gonna be stuck with factory specs?

    It’s great if you’re the putter around type driver, all about effeciency, but recognize you’re not everyone, and the Aptera was marketed to appeal to the acceleration freaks like myself, as well as efficiency nuts.

      ok, guys, here’s an old hack: Wanna get your 0-60s back?
      1) Get the off-road package

      2) Swap the tyres out for ones with a smaller radius

      You will get your 0-60 back. Your top speed will likely be 88 MPH instead of 101, but hey, you win some, you lose some. Enjoy! Oh, that’ll be $5.

      p.s. your spedometre will read that you’re going 87.5% of the speed you are really going, so you will be less likely to get a speeding ticket. Same as your odometre and your computer will report that you will run out of battery way before you actually do.

      But you’ll get your 0 – 60 back!

        Wrong. If you install smaller tires then the reported speed will be greater than actual speed, not less. When turning at the same RPM (reported speed) the tires will cover less ground (actual speed) than the speedometer is celebrated for.

    Thanks for posting. I am glad to see there is one other motorhead (besides myself) that appreciates acceleration.

    Beauty comes in many less obvious forms such as acceleration, braking, and suspension. Many others can only see the more obvious forms of beauty such as painting, sculpture, and nature. Those Philistines !

      I am an investor but will not be able to attend the webinar on Friday. Could someone that is attending please ask the question, if Aptera hasn’t already answered it by then, “why was the acceleration performance estimate downgraded to 4.0 seconds for 0-60?” Being conservative on specs? Gamma showed them that 0-60 in under 3.5 sec. wasn’t going to happen? Something else? Thanks in advance.

    I’m with you Jason. It’s a disease.

    Vroom vroom. 🏎

    Will have to wait for real world numbers before I change anything
