Tesla Roadster

By Deane Barker on July 20, 2006

Battery-Fueled Car Will Smoke You: Another superfast electric car. 0-60 in three seconds.

The trick? The Tesla Roadster is powered by 6,831 rechargeable lithium-ion batteries — the same cells that run a laptop computer. Range: 250 miles. Fuel efficiency: 1 to 2 cents per mile. Top speed: more than 130 mph. The first cars will be built at a factory in England and are slated to hit the market next summer. And Tesla Motors, Eberhard’s company, is already gearing up for a four-door battery-powered sedan.



  1. same cells that run a laptop computer

    i shudder at the cost of replacing those after two years…

  2. The company claims the batteries should last at least 100,000 miles before they need to be replaced. This type of roadster typically doesn’t rack up that many miles, people don’t usually commute or haul groceries in them. (Case in point: my 1997 Lotus Esprit with 18,000 miles on it.) It’s true the batteries will need replacing eventually and it will cost $XX,XXX — unless the price of batteries has fallen by then, which it might.

  3. I share Zobeid’s concerns about the batteries, but even worse, I’ve heard (but don’t know) that Lithium-Ion batteries degrade at about 20% per year even if you don’t use them! See more at

  4. If I could find a Electric Car that could run on batterys over 350 miles per overnight charge I’d buy it !!!! Just Buy the Extended Warranty on the batterys. And do Freeway speeds all Day long..

  5. I’m not a die hard fan of electric, but I hope the technology gets there. I know that Tesla site lists the discharge-recycle at 500+ and says that their testing shows greater than that.

    In an interview with CEO Elon Musk he said they were guaranteed to have 100k miles. I don’t know at what level of performance that guarantee would kick in, but at commercial rates right now that’s not a huge cost. It would eat into a lot of what you consider fuel savings, but all the added up oil/filter/belt and engine repair that go into a normal car offset that as well.

    There’s quite a lot of recent development in the battery world. Faster cycle times and less degradation. I know the 20% was for graphite Lith-ion and doesn’t hold for polymer style at all.

  6. I’m buying one. Settled today. I simply can’t stand how good this car is not to. It’s a bit expensive compared to a Lotus Elise, yes. But it comes with more complete kit and it fits my taste for a clean, trackworthy, agile performance car.

    When the mainstream manufacturers realize that car enthusiasts and people who recognize the imminent environmental crisis are not mutually exclusive, they should ring me. Because we’re here and we have money to spend. Until then, I’m putting the money they’re after where my mouth is and I’m buying a Tesla Roadster.
