Hi all,

Although I have not yet completed my current car project, I have already been planning the next one. After taking inspiration from the Midlana, my next car will be a scratch built mid-engine sports car. The design of my Midix has several key differences from the Midlana. In addition to some aesthetic differences that I wanted, I have designed my car to allow it to be used for as much daily driving as possible. Over the last few years, I have been putting together content to plan out the build, and I recently decided to turn this content into a website, which I have just launched:

https://midixsportscar.wordpress.com

Below are my CAD renderings of what the car will look like.

Due to time and space constraints, I do not plan on starting this build for a number of years, but I wanted to plan it out anyways well in advance.

Any feedback is welcome!

Interesting. You might want to run some type of "torque box" structure through the console area to stiffen the chassis. And raise the sides of the chassis up as high as you're comfortable with. GM did those two things to the C4 Corvette chassis, which still isn't the stiffest chassis around, but your roll cage can help with that.

Flip side, there were a lot of kit cars that got along just fine with a VW floorpan and some flexible fiberglass bodywork bolted to it...

Hi TRX, thanks for your feedback.

Good suggestion regarding the torque box through the center section. I had planned to add a tall tunnel structure through the cockpit section (similar to a Locost) to serve this purpose. I hadn't got around to adding them in the CAD model of the frame yet.

I had also thought about how tall I could make the sides of the frame that run underneath the door opening, but I suspect that I can't go much higher without making it difficult to get into and out of the car. As you mentioned, the roll cage should help quite a bit with keeping the frame from flexing.
