Determining Best EV Donor Cars (Electric Vehicle Conversion)


After you have considered what exactly you will need from your EV, (# passengers, cargo capacity, distance per charge, etc.) it appears that the curb weight of the vehicle is one of the most important aspects to consider. You are going to be adding nearly 3/4 of a ton of batteries to this puppy (in some cases), so the lighter you start, the better. MPG is stated here as it generally relates to the overall aerodynamic performance/ efficiency of the car or truck. The sample below are simply for comparison, and as the numbers have been culled from the internet - I can not guarentee accuracy. Not necessarily the absolute best choices. That has yet to be determined.



Year Vehicle Style Curb Weight MPG

1990 Geo Metro 2dr hatch 1650 lbs 38

1999 Hyundai Accent 2 dr hatch 2088 lbs 28/37

2000 Chevy s10 2 dr, 2wd, short 3,040 lbs. 23/29

2000 Chevy Camaro 2 dr coupe 3,306 19/30

2000 Jeep Cherokee 2 dr 2 wd 3,014 lbs. 20/24


Keep in mind that Curb weight is the weight of the vehicle, including all fluids without passengers or any cargo. Vehicles with a larger gasoline capacity will have a larger amout of weight attributed to the fuel. Example, the 1990 Geo Metro has a 10.6 gallon tank or holds approximately 84 lbs of gas, while the 2000 S10, with a 19 gallon capacity holds about. Keep this in mind when choosing a donor.


While I was compiling this list - I found someone else had already done the same, and with a little more detail. Check i t out at DIY Electric Car.
Other tips I keep coming across are;
1. Don't reinvent the wheel with your first conversion
Find something that has been done before. It means the parts exist, and potentially someone to ask for guidance should you hit a snag.
2. Use a car less that 10 years old.
As cars get older, parts are harder to locate. Factor in that you may not need replacement manufacturer parts until years in the future - so this seems like a darn good tip.

Daydreaming about EV Donor Cars - and more Questions

As I wait for my first Electric Vehicle book to come in (Convert It!), I have spent a lot of time cruising Craigs List for possible donor cars...and daydreaming. Keeping in mind that I have no clue what I am doing (ignorance is bliss, right?) lots of crazy ideas run through my head.

Ideally I want a 4 passenger vehicle with a 50 mile range and enough oomph to hit the highway, at least occassionally. If money were no object, then hey sure - why not a Hummer ... but I am trying desperately to keep my fantasies in the real word. (Not easy for an Aquarius)

The perfect car would weigh as much as a toaster and have the capacity to haul around the entire New England Patriots team ... as I haven't seen that yet - here are the ideas that bang around in my head.

If the Ford Ranger is such a good vehicle for conversion, why not the Bronco II? Pretty much the same vehicle with a back seat and a roof, right? Not the most aerodynamic of vehicles, I admit. OK, so the back seat and roof add extra weight. How much? I don't really know. Wouldn't the small cargo area in the back be perfect for battery storage, considering its size and proximity above the rear axel? Would a 4x4 come "stock" with enough extra suspension to fill my weight/ battery needs? Is it easy enough to just dump the 4x4 portion of the transmission and go 2wd? Again, Im not a mechanic. The big clue here is that I haven't seen one done as a home conversion online ... so I am guessing the other enthusiasts have ruled it out.


How about a mini van? A 7 passenger van should have a decent suspension, right? Remove the far back seat and theres plenty of room for batteries and 4 people, isn't there?



What about a Camaro or Firebird? I don't know about the suspension - but there is a ton of room under that hood isn't there? Even if the back seat is almost useless to begin with - heck - we aren't going too far on any given trip anyway - and it IS a backseat (read 4 passengers)

I realize, even if one of these is possible, I have a sneaking suspicion that my research will result in a smaller, more aerodynamic vehicle or a pickup truck - at least for my first conversion - leaving me with just a 2 seater. I can live with that. The VW bug is pretty easy to get ahold of - same with an S10 or similar small truck. I have secretly wanted a bug since before I ever had my drivers license anyway.


Whos knows? Really....Who Knows? I would love for others to weigh in. I'm actually trying to beg for insight ... without sounding like I am begging. Is it working?
