Home Brew Exo-Projects

Here is a car that I have been working on, the project started as a single seater reverse trike 3 wheeler and morphed into this. I am planning on hayabusa or ZX14 powerplant and most of the suspension is custom designed. I am using donor hubs, diff and steering rack.

I am not sure about which direction to go with the bodywork, I have been staring at this for too long! Let me know what you think (I will appreciate any feedback, even the negative!).

Welcome :wave:

Your cad design seems to have good start. What is your time line in building your creation?

The body seems to me big / wide, maybe it is my eye. What if the top body stops to the interior side rails?

[aaron540]

Thanks for the input, I think this body does make the car look wider than it is.

My time line is probably based more upon my daughter and my soon to be born son/daughter (this comes third to family and work). Probably 2-5 yrs to finish the design and build. I have so far only machined brake brackets (on my home brew cnc mill, another project that I am still working on) and I have purchased the shocks, steering rack and steering wheel. But I do have the big chunks of aluminum for most of the machined pieces (2X6 in section for the uprights!).

I am trying to lock in the chassis design so I can start getting some tubing rolled and start having some fun with the welding.

I like it! It seems like the motor may want to rotate towards the back a little more to have better access to the heads. It will raise the center of gravity slightly, but I would do it anyway for easy maintenance / repair. Or if the seat is easily removed you could work on it that way too. Have fun!

Here is what I had started designing, initially I was interested in a Radical SR3 like car. Then my interests turned toward a 3 wheeled single seater exo car. I still think the 3 wheeler would be an awesome car, I am kind of torn between the two cars. I think its nice to be able to carry a passenger. I would probably be building the 4 wheeler design below if it didn't take so much time and money to make a decent body.

Those first sketches of the reverse trike design are somewhat similar to the Peugeot 20CUP that has just been announced.

Ya, there are a few others also, VW's GX3 and the SUB are 2 other pretty cool looking 3 wheelers. I had designed a reverse-trike 3 wheeler solar car in college and the biggest problem we had was the CG ended up too close to the front wheels so during braking the weight transfer created a dangerous situation were the car would easily spin. I had read that the Peugeot 20CUP had a similar problem. With the exo 3 wheeler I was working on I tried to keep the weight evenly distributed between the 3 wheels to minimize the tendency to spin out under heavy braking.

Hi Aaron,

Nice project and I like the idea of a 3wheeler that trasforms into a 4wheeler very much.

Looking forward to more of your Cad work and if you're interested, I could work out a few rough sketches of mine for your chassis, just for fun of it......:)

Cheers

I like the new two seater four wheeler design. Please keep us updated on your project.
