Well I thought that I'd post about my thoughts for an aerodynamic first gen Z car.
The goal for this theoretical car:
1. Street legal (lights, signals, wipers, etc...) and feasibly driveable for around town use.
2. Provide ample downforce in the 70-140MPH range.
3. Reduce drag to a minimal amount to increase the effectiveness of horsepower when a car is being run in a category with limited engine work.
4. Still look like a Z car when finished (no radical roof, front end, or rear end changes that alter the personality of the car)
5. Be affordable for most people (body shaping under $4,000 for DIY in a garage)
I believe that the G-nose is an excellent starting point for front end enhancements but not the end-all "fix" to the lift/drag problem. In fact a regular Gnose may even make the lift problem worse without an air dam by acting as a funnel to cram air under the car.
Here is an initial sketch that I never finished because I changed my mind about some things. (never erase designs...they could be good to look back upon)
Now I do have some alterations that I will make to this design. The front end seems very good for a top speed car but may not provide adequate cooling and venting for a track/street car.
After watching NASCAR for several hours and looking at the high downforce/low drag/high cooling concepts I have a few new front end ideas.
I will address issues such as underbody airflow, wheelwell problems, front end treatments, hatch work, and other treatments to the car that will improve aerodynamics but not go too heavily into $$$$.
Note,
I am a Mecanical Engineering student so I am still working my head around many of these subjects but I have put many hours into reading about aerodynamics just so I could apply this to my aspirations to be a good all-around engineer.
OTM
