How difficult/expensive would it be to convert a rwd import into an electric car with the motor(s) in the trunk? Would it be better to have the batteries closer to the motor or in the front where the engine would normally be? Would it be better to have an independent motor for each wheel or just one motor for both wheels? Is there any way to get a car like this to 120-140 mph? What would be the best car to try with as far as lightweight? I am obviously not a car guy, and this is just an idea for a project if it is possible to accomplish. This car would be built like a racer/drifter depending on what is possible.
Please no haters, this is just curiosity.
@dick car guy- What if the car was for short races, 1/4 mile or short drift courses. and the transport was mainly towed by trailer? Wouldn't it require less batteries and possibly offer longer battery life from less use?

well I was looking this up myself yesterday, and from what I read it's enough info to discourage me from wanting to convert unless my engine dies on me. What I picked up from research generally was a complete kit will cost anywhere between 4000-8000 dollars, u need countless hours of work or you can get someone to do the work for you for $3000, and mileage and speed is limited (around 50-100 miles on a full charge and up to 80 mph). Oh you also need your entire front engine bay and a good part of your trunk to house the bulky batteries used to power your vehicle.
I'm not trying to discourage you from going through with this conversion, I'm just letting you know it's not easy.
If you really want an electric car, I suggest you search around your area where someone is selling his/her already converted electric car. Although theres only a few out there, you're bound to find some. Good luck on your project!

Is it possible to buy a hybrid or electric conversion kit for a conventional gasoline engine car?

wow
I was thinking about buying a bmw 3 series sedan but the only thing holding me back is the fuel mileage it gets. I started looking into conversion kits that can turn a car into a hybrid or electric car. I couldn't find any specific kits so I don't know if the technology is out yet. Could someone please tell me if it is those kits are out there. Please list as much info as possible!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks

If you are shopping BMW's, you are not worried about MPG. It doesn't just the MPG because if its a performance engine, you will be buying the highest octane gas by mandate of the maker, or else the engine pings to an early death which might the goal if you want to get a new engine.
Here is reality. Yes, you can put in an electric or hybrid engine, but it will have to be retrofit, as there is no such thing as plug and play on car engines, even from the same maker. So it will take a lot mechanical rigging and working to get it in the car, much less tuned and reliable. I would expect to pay a good mechanic four times what it would cost to replace the engine, with the idea that it could go up to eight times depending on what gets involved once he digs into it. So instead of $3k, you might want to have between $12-24k just for the conversion minus the price of the car.
Here is the other part and scary engineering that you will get into is where to put the battery bank, what kind of batteries will you buy. If you want good batteries, expect to chunk in another $20k. But it doesn't stop there, what about the braking system that generates some of the electricity of the hybrid? What about the computer system that operates the engine and dc motors? Get out your wallet for that too...
So once you get done, your near $60k in a conversion, minus the price of the car, you might not have it working. Just look at the common issues with electric cars http://answers.yahoo.com/question/index;_ylt=AqWgEK1EFb2vwPcUKTPSW5h0.Bd.;_ylv=3?qid=20090610220941AAokgel
Why not just go buy a Prius as a donor and save yourself the engineering. Or better yet, just go buy a hybrid ready to roll with e-z financing?
