  • Studebaker entered the automotive business in 1902 with electric vehicles and in 1904 with gasoline vehicles, all sold under the name "Studebaker Automobile Company".

    In their final year of production, 1965, Studebaker made just under 20,000 vehicles. The company produced gasoline cars from 1912 to 1965. It is unknown how many total vehicles they produced and sold

    elio

    Each Elio comes equipped with a Safety Management System that includes three airbags – a reinforced roll-cage frame, Anti-Lock Braking System, and 50% larger crush zones than similar vehicles.

  • The efficiency of the power plant and distribution network in delivering the electrical "juice" to the Tesla is ~ 30%, i.e. the REAL "fuel consumed" at the power plant (in terms of oil, natural gas, wind power) for the Tesla translates to only 40 to 43 mpg. Surprised?

    The reason for the much higher "fuel consumption" of the Tesla is that it must carry an extra 425kg of batteries (~5 people) all the time. No fuel tank that gets lighter on "empty".

    And this does not yet consider the issue of having to heat the Tesla. The drive train of the Tesla produces no "waste" heat. That waste heat from combustion of gasoline in a normal car is 70% of the total. It comes "free". For the Tesla the waste heat stays at the electrical power plant. For any Electrical Vehicle in a cold winter you must therefore add ~ 30% in fuel consumption (or the mpg divided by 1.3). Now the Tesla is down to 35 mpg..

    Giga factory breaking ground date

    The only explaination I can think of is that he might break ground this month at several locations and decide which one he will use at the end of the year. That is still an expensive approach, buy the land, start developing them, and then decide which one to use. Never heard of that approach before. Only 27 days left in June to find out

  • Which one is it going to be

    Today's news
    Musk also said that Tesla will not pick a final site for its long-awaited "Gigafactory" until the end of the year. The goal of the plant is to mass-produce lithium-ion batteries and lower their cost.

    May 7 News
    Tesla Motors founder Elon Musk said Wednesday that his electric car company would break ground sometime next month on its $5 billion “gigafactory,” with a rival site to break ground a month or two later

    I don't disagree with most of your posts, just pointing out the fact that coal is used, And what about China which is suppose to be one of their large markets. It is years away from getting away from coal. The model S and other current electric cars will be obsolete while some ICE vehicles are improving their mileage over 50 MPG already. Who knows which will be greener/less expensive by then, how fuel cells, solar power etc.

    Google "how green is TESLA" for some current answers.

  • SpaceX Dragon Version 2 Uses 3-D Printing for Rockets

    Elon Musk introduced the latest spacecraft from his company SpaceX, the Dragon Version 2. In a short presentation yesterday evening from SpaceX headquarters, Musk dropped the drape on the spaceship designed to hold seven passengers and built to be reused. The operating panel pulled downed from above the seats and resembled a large Tesla dashboard. Musk called the interior esthetically pleasing in that it was clean and simple. The rockets are printed from a 3-D printer that uses a special high strength alloy, making the idea of 3-D printers more than a novelty for crafts.

    So if you’re going to stack a Tesla’s per-mile emissions against those of a gas-powered vehicle, you’ll need to start by looking at the composition of the electrical grid. Nationally, the grid is roughly 40 percent coal, 25 percent natural gas, 20 percent nuclear power, and about 10 percent renewable sources, led by hydroelectricity. So it’s fair to say that your average Tesla is powered in large part by burning fossil fuels(40% produced by coal).

    The California New Car Dealers Association asked the state Department of Motor Vehicles to investigate Tesla Motors advertising practices that it claims “deceive consumers by making unsubstantiated and illegal savings claims in violation of several state and federal laws.”

    The auto dealers group said it had documented numerous examples of Tesla’s “disregard for the laws created to protect consumers” and calls the Palo Alto, Calif.-based electric vehicle startup’s practices illegal.

    The group said its “analysis exposes the company’s misleading claims that customers can take advantage of multiple incentives, gas savings, and tax savings resulting in low monthly vehicle payments, when it is unlikely that customers will actually realize such savings

    Fifty years after he became the first drag racer to break 200 miles per hour in the quarter-mile, Don Garlits is aiming to hit that mark again -- only this time in an electric car.

    ADVERTISEMENT
    ADVERTISEMENT

    The 82-year-old’s Swamp Rat 37 is a high-tech dragster fitted with a 2000 horsepower electric powertrain that’s as quick as it is quiet.

    The car is a collaborative effort with several electric racing specialists, including battery manufacturer High Tech Systems and powertrain builder Lawless Industries.

    The rail dragster features six GE motors connected to a two-speed rear end and can hit the 60-foot mark about as quickly as the nitromethane-powered monsters in the National Hot Rod Association.

    Garlits said the difference is that everything is really silent at the starting line, but then “you step on the go pedal and, I mean, you take a ride!”

    During a shakedown run at Bradenton Motorsports Park on April 30, Garlits made a 7.258-second pass at 184 mph, breaking a widely-recognized existing record of 156 mph.

    a 220 volt gas generator will run about 5 hours on 5 gallons of gas(about $25 per charge)

  • Tesla claims a person will get a $1900 per month savings over a comparitive vehicle over 3 years due to it's guarenteed resale value. How can that be true($68,400 savings on resale value)

    Guaranteed Resale Value
    If you do your financing with Tesla, we guarantee that the Model S will have the top residual value of any high volume premium sedan brand (Audi, BMW, Mercedes or Lexus) after three years of ownership. Spread over 36 months, it means your effective monthly payment is lower by this amount.
    -$1,906 / mo.

    I have to guess the thumbs down is directed at TESLA because Elon made these statements, their not mine

    Assumptions used from TESLA website on savings for not having to spend time at a gas station vs charging

    "Detouring to a gas station and refilling the tank takes time out of your day. Plugging in Model S takes seconds, just like your phone, and you’ll wake up to a full charge every day.

    Monthly gas stops
    Time spent driving to a gas station and refueling 10 Minutes
    What’s your time worth? $50/hour"

  • cbx6cylinder cbx6cylinder May 29, 2014 2:07 PM Flag

    Found this
    "Tesla says the 60-kwh battery provides a range of up to 232 miles (the EPA pegs it at 208 miles), and the 85-kwh battery (a $10,000 option) provides up to 300 miles (the EPA puts it at 265 miles). Here are some examples for recharging times: With a single onboard charger plugged into a standard 110-volt outlet, Tesla says you will get 5 miles of range for every hour of charging. From zero to 300 miles would take about 52 hours at that rate. With a single charger connected to a 240-volt outlet, which Tesla recommends, the pace speeds up to 31 miles of range for each hour of charging, and a full 300-mile charge takes less than 9.5 hours"

  • cbx6cylinder cbx6cylinder May 29, 2014 2:03 PM Flag

    If that is true, at 13K miles per year, it would be about 3500 hours of charging on 110V per year. Another way to look at that is 3.7 hours per mile assuming that 81 hours is based on a 300 mile battery

    Of course, no one uses 110V to charge.

    Model S ======= failure

    The battery savings alaone from the giga factory won't get them there on the model S if this article has any truth to it. Lot's of other savings will need to come from elsewhere

    "If Tesla's all-in current battery pack cost is $260/kWh (the most widely rumored number), it would mean that the S60's pack costs the company $15,600. If this were to be shrunk down to a 48kWh pack for the Model E, it would reduce the cost (at today's prices) to $12,480. If the company were able to then further cut that cost by 35% thanks to the gigafactory, it would reduce the 48 kWh Model E battery pack cost to $8112 which would be $7488 cheaper than the S60's battery. Essentially then, if we put the "2017 gigafactory priced Model E48 battery" into today's S60, there would be an estimated savings per car of $7488"
