Daimler (the parent company of Mercedes-Benz) has revealed more specifications of the electric version of the Mercedes-Benz SLS AMG.

Here are the currently released specs of this beautiful car:

  • 740 HP propulsion system.
  • 738 foot-pounds of torque.
  • A top speed of 155 MPH.
  • 0 to 60 MPH acceleration time of 3.9 seconds. Despite the heavy weight of electric vehicles, their high-torque motors can still get them going quickly.
  • 60 kWh battery bank. This is large enough to power about 40 American homes simultaneously for an hour. This battery pack weighs 1,200 pounds.
  • A curb weight of 4,600 pounds.
  • Plays sounds when starting, stopping, and moving. (Personally, I think it is time for people to let go of engine sounds, if they are not real — there is no point in bothering with them!)

Maybe I should start mentioning the number of houses electric car batteries can power, since they can be used (with the right infrastructure) to back up the electricity grid. We are moving towards a future in which electric cars may actually be used to back up solar, wind, and other power plants. Utility company CEOs and others have been discussing this for awhile. What do you think — should we start including number of houses electric car batteries can power in such posts?

Before getting to excited about this Mercedes supercar, you might want to check out the price tag. The electric Mercedes-Benz SLS AMG is to be sold for $538,000 (i.e a whole ton of monopoly money). Nonetheless, the green light has been given for production. Good for those in the 0.01% who want to drive an electric supercar.

While this may not seem relevant to most of us, however, because of the high price, the technology resulting from the research and development of such a high-end vehicle — a vehicle pushing the boundaries of technology —  could trickle down to lower-end technologies. It’s likely that it will. What Mercedes learns from this fun project could help the company (or others) design cheaper mid-range electric vehicles for the masses. We’ll see.

    About the house powering option – couldn’t hurt, but it’s not really that useful. We have a lot of business people talking about how electric cars could stabilize electric grids, and while they could do this by actively controlling their power demand, they will not (or should not anyway) be used to supply power to the grid unless battery technology changes significantly. From the perspective of the Engineers who design these systems – they simply are not designed to handle that yet.

    “Good of those in the 0.01% who want to drive an electric car. ” => Sounds like very few people want to drive electric cars. I understand what you meant, but consider rewording.

    • Ronald Brakels

      Sometimes the spot price of electricity goes over $10 a kilowatt-hour here. That’s more than enough to pay for battery pack wear and tear. A price difference of 30 cents between what electricity is bought and sold for should be enough to pay for itself, although one might want to go for a higher figure if one is pessimistic about how much it will cost to replace a car battery pack in the future.

      • Otis11

        Well, if those price differences are actually seen by the end user, yes it would make sense to use the car in this way, but it would actually make better sense just to get a battery pack for your home. The Home battery pack doesn’t have to have as high of charge density and so the cycling doesn’t matter as much as in a car.

        So while I can see some people wanting to do it, it will never be the best option given current battery technology.

    perhaps you should consider what is the price per kWh and estimated cycle life of the battery pack. Then you can calculate what is estimated price of electricity per kWh that is fed from vehicle into grid.

    You must remember that every time you are discharging EV battery, it reduces the value of EV, because it reduces the range. Do you really think that reducing range is worthy?

    The price of vehicle to grid electricity when using Tesla’s NCA batteries (life time around 2000 cycles) is something in order of $500 per MWh + the annoying range and value reduction of EV. At that price point, perhaps you would rather want to put into operation few extra coal plants to provide intermittent electricity!

    What EVs are good for is that Lithium batteries like that the charge is maintained as constant as possible at around 40 % of capacity. Therefore for daily commutes capacity range 20–40 % is more than enough. And only when there is plenty of wind and solar available, battery can be charged to the 90 % level that is maximum recommended charge level. Full charge and full discharge reduces the cycle life of EV batteries.

      I’ve also wonder anout using current EVs as grid backup. Time to they take extra power when there is too much yes. But with “only” 2000 cycles I don’t want to loose the range. Now when were are talking 10k-30k cycles, without real drop off, then grid backup is there. Now it is more backout for when the grid is gone.

    Maybe not number of houses, but number of hours would be a more descriptive energy unit since we are all inherently selfish and only want to think about our own house.
    By the way, where did you get the figure of 3kW per household from? I know my house is far below that, and according to “http://www.eia.gov/tools/faqs/faq.cfm?id=97&t=3″ the figure for American houses is about 1.3kW

    • Pete Stiles

      My annual average is 7 KwH per 24 hours so roughly 1/4 Kw per hour

      • http://www.facebook.com/jrpearce Justin R Pearce

        the units of kW already include a time dimension, so you get just a usage of 0.25 kW or 0.25kWh/h
