      Hopefully those improvements can be "backported" to the S and X, reducing their price.

      • why would they lower the prices on those? They compete against cars that are 50-100% more in price range. In addition, they will take about 1/3 to 1/2 of the market place in the 80-200K vehicles with these 2 and that is without a fraction of the salesfloor as well as no marketing budget, that MB, Audi, Caddy, BMW, Lexus, etc have.

        So, with that in mind, Why would they want to lower their price?

      Since the summary is unsurprisingly lacking any details, I found this feature the most important:

      "Tesla is shooting for a battery cost for the Model E of 30 to 40 percent less per kilowatt-hour than the Model S. This will help Tesla hit its price target of $30,000 to $40,000, competitive with the BMW 3-Series. Part of the cost reduction will presumably come from the huge "giga-factory" Tesla envisions to build Model E batteries."

      So.. it's vaporware. That's what we call it when a company pontificates about the amazing advancements of their not-yet-invented technology, right?

      Here's another, less 'vapor-y' statement from TFA:

      The Model X will actually have a lower drag coefficient than the super-slick Model S. But because of its increased frontal area, the total drag will be higher. Combined with a slightly heavier weight, the Model X will have an energy consumption about 10 percent higher than the Model S. (Musk did not say whether the Model X battery size would be increased in order to maintain the same range as the Model S.)

      So, it's going to be heavier, create more drag, and use more energy (and thus, probably have a lower range) than a Tesla S. Oh, and it has AWD standard, and all sorts of fancy electronics to keep those gullwing doors (because that's what those are called, Elon) from whacking into stuff.

              The Lambo doors are fragile. Single mount point requiring frame stiffening. Open them in a garage, and you better have 4 feet of clear space above because that is how far they stick up. (There are parking garages with way less than that).

Regular (manual) car transmissions already impose a ~15% hit on fuel economy; that's how much energy is lost just using some gears to multiply your torque (and decrease the output shaft rpm by a proportional amount). CV joints also impose a fuel-economy hit. Of course, it's pretty hard to drive without these, so we accept them, but putting more gea

As it is he's got no chance of selling US-centric cars in the rest of the world and will forever be painting himself into a niche.

          "The golf segment" means "compact car". I think "Mid size" would be generous. If you want a compact, Tesla is not catering to you. Sorry. Largely due to the fact that even in a smaller dress (Like the original Tesla Roadster) it will still be outrageously expensive (Like the original Tesla Roadster) for its size.

          If you want something right now, your best bet is probably a Ford CMax or Nissan Leaf. The stupid little thing that Mistubishi is pushing is a city car. While they have their applications,

    • Tesla should have concentrated on producing a credible hatchback, Volkswagen Golf competitor they could sell worldwide. If they could get a section of that market then things would change very rapidly.

      Just like Nissan has with the Leaf? Or Mitsubishi with the i-Miev? Or Honda with the Fit Electric? Chevy Spark? Focus Electric?

      There's a whole lot of competition in that market; I don't think it'd be unfair to credit Tesla's relative success with the fact that they DIDN'T try to do that.

      • Just like Nissan has with the Leaf?

        The Golf market segment is not one inhabited by the Leaf. That's just daft.

    • And you do realize that the Model S and Model X are BOTH hatchbacks!!!

      An all electric Golf-sized hatchback that costs $60k+ would be a much smaller niche than a full-size CUV at the same price point. Tesla will supposedly build a $40K Model E as their low end sedan, but the Model X will be much more expensive. Your Golf competitor already exists. It is the Nissan Leaf.
      • They would have to make it cost less then $60,000, and there would be the challenge and the potential.

        Anyone who thinks the Nissan Leaf is a Golf competitor is an idiot.
        • Actually, you are the idiot. VW is now delivering e-golf, has a weaker motor, much slower speeds (the golf will do 0-100 km in 11.2, the regular leaf does it in under 8), same distance and costs more.
          BUT, to make matters worse, they do NOTHING for the heat issue, in the same way that Nissan has blown this.

          The leaf is not that great, but it beats the daylights out of the e-golf (and the golf for that matter).
      • actually, the Model E is NOT their low-end sedan. It is an executive compact and will be their mid-range car. They actually have plans to deliver even lower price cars, but not until after 2020.
    • Amazing that you were modded up. The golf is a POS that ppl buy because it is cheaply made and over charged for. That is the LAST car that anybody should EVER consider copying.

      Instead, Tesla is doing the right thing. They are starting higher end, making profit that allows them to grow. At the same time, they are installing showrooms, service centers AND super chargers all over America and Europe. This is all funded by currently 30K cars / year, and next year, it will be 50K cars / year. Compared to the bi

  • Musk says AWD has never been put on a car with no loss of efficiency before.

    2012 Lincoln MKS:
    FWD version: 17/25 mpg.
    AWD version: 17/25 mpg. And the AWD version is more powerful.

    2013 Cadillac CTS:
    RWD version: 18/27 mpg.
    AWD version: 18/27 mpg. AWD version has same power (same engine) as RWD version.

    So yes, AWD has been added without a loss of efficiency before.

    Elon, it would be fantastic if you would bother to check to see if what you say is true before you say it.

      Both cars get around 1 MPG less with AWD compared to their 2WD counterparts with same engine. And for the Lincoln, SAME ENGINE is the key word. The AWD Lincoln is able to achieve the same MPG as the FWD one assuming you upgrade to the EcoBoost engine, which, while yes is more powerful, is a com

      He talks about no loss of efficiency with the SAME ENGINE. Check your examples, one does not have the same engine, the other doesn't really maintain efficiency if you check around for tests.

      Erm, these are not efficient cars. 18 MPG is 13L/100 KM which is shocking fuel economy.

      There is more loss to an AWD drive train compared to a FWD or RWD drive train, it can be minimised but its impossible to eliminate it. So chances are the Lincoln and Cadilac simply fudged the figures (easy to do when you already have shocking fuel economy).

  • Honestly, they would be wise to sell just the chassis with the drivetrain. That approach would allow for kit cars to be developed on these. I suspect that it would also lead to other companies developing some interesting type cars.
