Tesla Roadster Runs For 241 Miles In E-Rally

N!NJA writes with the mention of a recent alternative energies rally where the Tesla Roadster managed to cover 241 miles on a single charge, with another 38 miles of juice still left in the battery. "That would give the Roadster a theoretical maximum touring range of nearly 280 miles — 36 miles more than Tesla itself reckons the car will cover on a charge. If the numbers stand up to official scrutiny, Tesla will hold the world record for the longest distance traveled by a production electric car on a single charge. Of course, it should be pointed out that the Tesla was driven by a company staffer doubtless practiced in eking out every last mile from a charge, and that the speeds averaged on the run were hardly blistering — 90kph (56mph) on the motorways, 60kph (37mph) on trunk roads and 30kph (19) in the mountain roads. Tesla reckon the average speed for the entire journey was 45kph (28mph)."

      Ok, I guess if you have a family, but the parent poster was, I think, referring to making something like the Tesla more affordable....a 2 seat, well crafted, performance vehicle that doesn't look like a fugly Prius.

      Most people can only afford one car, and most people need a family car. So that one car will be a family car.

      They'll get as excited as they can in buying that car. If they're given the choice between a KIA or BMW sedan, they'll get excited by the BMW.

      If Tesla can make an exciting, innovative family-sized car, they'll find themselves with a big market.

Of course, I can then instantly fill it back up at any of the very abundant filling stations around the country/world, and it runs just as well with the tank nearly empty as it does with it full (actually better, on account of the missing weight).

They have better torque characteristics, less moving parts and simpler maintenance. Once battery technology advances enough that the range is acceptable, electric cars will take over from combustion engine cars because they are simply better vehicles.

    When you look at the amount of energy stored in a gallon of gasoline compared to a ton of batteries you'll see why.

    That's just silly, though. EVs are exactly the opposite paradigm as gasoline cars. In gasoline cars, the fuel is light while the engine is heavy. In electric cars, the motor is light while the batteries are heavy. The Roadster gets its performance with a motor the size of a small watermelon that weighs something like 40 pounds. In short, battery packs aren't competing with the gas tank for weight and space; they're competing with the gasoline car's engine for weight and space. If you crunch the numbers, you'll find that the two powertrains will be approximately the same when batteries hit 350Wh/kg or so. Commercial cells currently top out at about 200Wh/kg, but there are about two dozen different techs in the lab that can 50%-800% increase the energy density of their respective electrode (anode or cathode). The odds of every last one of them failing to make it to commercialization are vanishingly small. Li-ion still has a very long run ahead of it.

    Don't you think if there was money to be made in this market someone would have tried when gas was over 4 bucks a gallon?

    When do you think it was that several dozen different marques announced EV programs? Nowadays, it's easier to count the companies that *don't* have EVs they're planning to mass produce. For example, among the biggest sellers in the US, there's only one: Honda. And they've already announced plans to make an electric motorcycle, so even they may not count.

    I drove 280 miles today (central NY to upstate) and it took me 3.5 hours, meaning I traveled an average speed of 80mph for the journey. Even at an average of 65mph (the proper speed limit) the journey would take 4.3 hours. 4 hours is a far cry from 10 hours traveling.

    What are you talking about? Your average person is not traveling 4.3 hours every day. Indeed even you didn't travel 4.3 hours every day. and I severally doubt you averaged 80mph. Hook up a meter to your car. Stopping for gas and/or eating, pissing or whatever tanks your average. You probably averaged less than 50mph. Trust me.

    While gas (and money) is a commodity that I would save by traveling with an automobile than ran on an alternative fuel source, there is a negative cost, an exchange of time. I save money, but I lose time. If you calculate how much I get paid an hour and convert the lost hours to dollars, it's more cost efficient for me to take a gas powered car over 4 hours than an electric car for 10 hours.

    The Tesla can easily keep up with your silly assed car. The only time wasters is if you have to recharge, which is generally done at night when you aren't billing any of those precious and expensive billable hours anyway!

    Even if the electric (or alternative fuel source) cars are cheaper to run and operate, time must also be factored in as a commodity, and weighed accordingly. But if these cars continue to run at considerably slower speeds than gas fueled cars I don't see many people shifting to them.

    Yes, with the key word here being "weighed". Comparing a long haul drive is not a fair comparison at all and it's not what you usually do. Most people drive 30 miles a day on average. You need to weigh for that heavily. Many people drive cars that are way underpowered compared to a Tesla. You sound like an idiot who doesn't know the first thing about what you are talking about!

    Very true, but how often do you drive the car 250 miles in a day, where you can't park it somewhere to charge overnight?

    I'm very impressed with the 241 miles the car managed to get. This is a real road course, not some "range of 200 miles" crap we keep hearing, where 200 miles is if it's rolling off a mountain and you'll really be lucky to get 100 miles. This course covered highways and mountain roads, with varying speeds and inclines. No fakery here, and it had room to spare. Gives me a lot of hope that electric cars could actually be realistic.

    Now if they could just shove a small gas generator in there somewhere so I don't have to worry about being stranded. I'd rather get going again with a 5 gallon gas can then waiting for a tow truck.

    When driving the Tesla Roadster like a sports car you'll get much lower mileage. Jeremy Clarkson only got 55 miles around the Top Gear track, as you can see in this poor quality clip.

    The remaining problem with viable full electric vehicles is energy storage. You need to solve the problems of capacity, charge time, and duty in all weather conditions. Perhaps a high density ultra-capacitor can solve these problems but no one has demonstrated a production unit yet. Maybe 2009 will be EEStor's year but who knows. It's also possible that hydrogen fueled vehicles will become the more practical option, despite the high cost of developing the refining and distribution infrastructure to support them.

For years after the oil crisis people were demanding fuel efficient autos but the big 3 wouldn't offer them. So the Japanese auto makers ate their lunch by making more efficient cars. That was when Japanese cars had to be imported and weren't made in the US. Eventually Detroit started importing Japanese cars but rebranded them. I once bought a Chevy branded truck but when I opened it up to work on the engine it was a Japanese company that made it.
