Honda's S2000 developed a reception as a great handling sports car over the past decade. Unfortunately for fans of torque, its high-revving four cylinder was found severely lacking. One S2000 owner has come up with a solution, and it's also greener than your average Honda roadster. We don't really know many details about this car or the owner, but it has apparently been converted to electric drive. The owner recently took his first drive after hooking up the batteries and has posted the video on YouTube. If anyone out there knows the owner of this car, please have him contact ABG and fill us in on the details of this story. In the meantime you can check out the video after the jump.

Update: Thanks to reader matthijs for jumping in with a link to a blog that documents the development of this 2003 S2000. The owner actually used lithium ion cells from Thundersky totalling 23 kWh, so it will be interesting to see how the car performs.

      Whiney Curtis controller and the loudest vacuum pump I've ever heard. Why cut corners when you spend big bucks on lithium??

      That's a great project, and a really good blog. Nevertheless, I was pretty surprised when I saw the choice of motor. The ADC is a beefy motor, but I don't know if it's up to the task of moving a 3000lbs car around town. I used that motor in an 800lbs snowmobile, and it was okay (that said, that was at only 72 Volts). I'm just a little worried the motor will get overworked while trying to keep up with traffic and he might hit that temperature limit in the motor. If I were him I would have looked at maybe ditching the transmission too and getting a more powerful motor.

      HP is what gets you performance numbers, not torque, do some reading on the concept. More HP will always win. Nobody cares about torque.

      Im interrested to buy the old ice along with the old engine management unit.

      There is PLENTY of road noise from the tires for the blind to know that a car is coming, however the controller manufacturers need to do something about the controller whine and power steering & power brake pumps which are annoying.

      GOOD JOB!

      If one values efficiency over performance, one converts a Prius into a plug-in or a Honda CRX to electric. But an S2000 is already pretty efficient as is for a car that can go 0-60 in 6.7.

      And I'd prefer you not sniff at me as if you're so superior. Unless you've foresworn the use of plastic and electronics, the consumption of beef, dairy products, and other meats, and the heating or cooling of your home or place of residence, you've got a pretty sizable carbon footprint yourself. Given that you're obviously using a computer and almost certainly not living without climate control, that makes you a hypocrite.

        You think I'm a stoplight racer, huh? Thanks for the laugh.
        • 8 Months Ago
        I do believe you have some personal issues if you think I'm directing it at you. It has nothing to do with superiority. You asked why one would do that and I answered it. The fact of the matter is people drive what they drive and drive the way they drive as a reflection of their personality.

        Last I checked, most S2000 owners are big tools. If someone has an S2000 and doesn't act like he's got a cracker up his behind while getting to the next light, that's a breakthrough in personality and level of comfort with oneself. If that strikes a nerve with you, too bad for you.

        If using the computer usage thing is your best come-back to a personality problem, try again.

        The S2000 is not terribly efficient. It gets worse highway mileage than a Corvette, which has twice the HP and is large enough to have a usable trunk. And a Corvette does 0-60 in 4.6 seconds.
        • 8 Months Ago
        You bring it on yourself for me to think that. My original comment was neither directed AT you or named you. You chose to do that...for whatever God-forsaken reason only you can answer.

      I love electric cars, but why would you convert your car to electric if it means sacrificing a good 3+ seconds on your 0-60 time (and probably the balanced weight distribution to boot)?
        • 8 Months Ago
        I know perfectly well that electric drive makes better performance possible, but the spec sheet Marc linked to estimates the 0-60 time at 10 seconds.
        • 8 Months Ago
        Petroleum is a non-renewable, expensive, polluting, inefficient hydrocarbon fuel and it starts bloody conflicts between nations. That's why you would convert a S2000.

        The original S2000 is a awsome car, oil burner or not.

        Torque at the wheels is acceleration. But torque at the wheels is determined by both torque and speed at the engine output shaft. And HP measures both torque and speed, torque does not.

        And engine will more HP and the right gearing will out accelerate one with less HP (even if it has more rated torque) every time.

        Electric cars have better drag racing times than electric cars.

        Electric = more torque
        gasoline= more horsepower

        torque = acceleration

      Converting a Honda S2000 to electric is like performing a mastectomy on a Playboy Bunny.
      • 8 Months Ago
      Thinking ahead 15 years or so to high gas prices and carbon taxes and I might consider such a conversion with my 2002 S2000. There would have to be advances to the lithium cells as far as output and cost are concerned to make this worthwhile.


      "Last I checked, most S2000 owners are big tools." - Please lets stop with the anecdotes, personal attacks, and stereotypes. Maturity: Look into it.

        My S2000 gets between 22 and 28, depending on how heavy my foot is on any given day. 30 is possible when driven conservatively

        Stop quoting just combined figures when comparing cars. You can only get away with quoting just combined figures if you happen to drive exactly 45% of the time on the highway.

        My point was not that the Corvette is more efficient than the S2000. It is that the S2000 is not particularly efficient. If it were efficient, a car that makes twice the HP and is much larger could not match it, even on the expressway.

        How about a Cobalt SS? More HP. Far faster and more powerful, handles approximately as well, costs less and gets 25 combined (22/30). And this despite only having a 5-speed. And it can carry 4 people, and is even available with 4 doors.

        The S2000 is not particularly efficient.
        • 8 Months Ago
        People use the highway figures to inflate probable MPGs. Most people do a mix of highway and city driving hence my approach. 45% is a more realistic figure than 0%

        Actually the auto corvette get 18 MPG avg with 15 in town. Figures I have never seen on my S2k except at the track. And once more you have to pay more for a Corvette to get less mpg.

        You can't compare the utility of a Cobalt vs. that of the S2k b/c they have totally different goals.
        Why do they make 2 seat roadsters at all would be the next question in that stream of logic. People should buy Mazda 3s instead of Miatas?
        • 8 Months Ago
        No, not at all.
        Why Not knows that a S2200 was a play thing, where the Vette has to be practical.
        and to stop any strawman arguments. (Honda knows that they could have had better gearing. S2000 5,8,11,13,17,20, S2200 4,8,12,16,20,24)

        The Cobalt SS isn't really faster than the S2200, it runs neck & neck in the 1/4.

        An electric S2000 is a blank canvas, a huge blank canvas.
        There is so much room to stick loads of batteries once you remove the engine, transmission/driveshaft, exhaust system, coolant system.
        The x-frame chassis should keep the batteries low and centrally mounted, I would have been more enthused if they would have done a nice burnout in the video.

        If an electric S2000 had a 45/55 weight distribution (like a Boxster) pulls 12@110 in the 1/4, then mission accomplished could be waved.
        Maybe CR quicker steering ratio & wider rear tire?
        • 8 Months Ago
        The S2200 doesn't have variable valve timing or eEGR.
        That plus absurdly shortly gearing means crap mileage.
        and top speed is in 6th gear where the Vette is 5th.
        (can the S2200 do 150 with the top down?)
        6th gear of the S2200 is shorter than 4th of the Cobalt SS (where is the direct injection Honda?)
        3rd gear of the Vette auto is taller than 6th of the S2200
        6th gear of the Vette stick is more than twice as tall as the S2200 6th gear (even the Z51 package too 0.57 vs 0.50)

        Hey MikeW I think you are using this thread just as an excuse to put down a discontinued car and that you have no interest in the electric S2000 at all. That you just like to compare other makes to GM products b/c you envision yourself as their great defender and that you have no interest in the green theme of this blog in general.
      • 6 Years Ago
      Well..I guess some people value efficiency and other things over 0-60. One has to outgrow that nonsense. Sign of maturity.
