I'm looking for a car to convert to run off electric and I need some data on the Opel GT that I haven't been able to find, to see if it would be a suitable choice.
I have the curb weight, gear ratios, and rim sizes.
I do need, however, the following information:
What is the drag coefficient of the vehicle?
What is the frontal area of the vehicle?
Do you happen to have the gross vehicle weight rating? How about for front and rear?
Dry weight of the vehicle?
What is the approxamate weight of the engine?
Weight of gas tank and fuel feed systems?
Weight of the exhaust systems?
Any idea on the amount of space within the engine area and the trunk area? Dimensions?
Also, what sorts of suspension upgrades could I use if I wanted to increase the maximum gross vehicle weight rating? Are there any particular leaf spring sizes I'd need?
My intent is to cheaply build an electric vehicle that gets 0-60 MPH ~7 seconds, tops out at around 120, 1/4 mile in high 15 seconds or less, does approxamately 80 miles per charge at a steady highway speed(Or 120-ish on a cycle drive), and can handle at least as well as the .83g it attained on a 216 foot skidpad back in '73, preferably better though. This would entail using 20 Evercell MB80 nickel zinc batteries 12V nominal weighing at 50.2 lbs each all wired in series(For a total of 1004 lbs. of batteries and 240 volts), a DCP Raptor 600 controller that's 18 lbs, and an ADC 9-inch series wound motor weighing in at 143 lbs. Add in about 400 pounds for driver, adaptor plate, wires, fuses, ect.
In order for this car to be suitable, I will need to keep final curb weight below 2,700 lbs and I'm looking for an overall Cd.A of less than 5.5(Coefficient drag times frontal area in square feet).
The Evercells have a power density of 280 watts per kilogram, meaning, I'd be able to push about 170 horsepower maximum through the motor(Not constantly though, I'd damage the batteries if they were nickel zinc.). The torque from start up would be able to smoke tires, so I'd probably need a different tranny and drive axel so I don't break anything. But lets say the car weighs 2,700 pounds. That's a power to weight ratio of .063, which given that electric vehicles produce peak torque from start, this would be well capable of impressive acceleration, easily in that target I'm looking for. The aerodynamics are a huge factor in energy consumption and acceleration past 40 mph, thus they are also important. I'd want to place as many batteries as possible towards the center of the car, usually behind the driver's seat, to keep the weight balanced and to keep the center of gravity as low as possible to nail the car to the ground.
All in all, this would cost me about $10,000.
If this car can meet my needs, I'll be buying one in the near future. If not, I'll keep looking somewhere else.
This is intended to be a starter project, at least until I'm able to build a car from the ground up.
Thanks.
