Aeromotor, yes this is Grassroots

 Couple of more images of the new chassis. Seen in the background is the old chassis.

This thing is straight ridiculous! Keep up the good work!!

 Thank you! That project took a lot of time, but it was worth it and the new chassis and interior panels truly redefine the car now. Cheers!

Inspirational work. Great art. 

Thanks for posting here AeroM, too bad I missed your earlier responses...7+ years ago

Getting back to my original question, I see you're now running an Audi V8 engine in your latest prototype, are you also using the Audi transaxle?

 Thank you all for the kind words! I appreaciate your opinion! Oh, and Happy New year!

In reply to GameboyRMH :

 Except for the original old chassis that used a PRV V6 engine coupled with Renault 5-speed manual transaxle, all the next chassis used an AUDI V8 4.2L engine producing 340HP. However, I'm not sure about the exact transaxle model for this one since I'm only the designer of the chassis, suspension and body as a sub-contractor, whereas the manufacturing of the kit and optional installation of the drivetrain through the years was done by "Aeromaster sportscars" upon individual customer specifications that vary for every kit. I designed the newer Pro chassis pictured above to utilize a widely available transaxle from "Getrag" used in 2006-2008 Cayman S, Boxster S, and Cayman R (like this one: http://forums.pelicanparts.com/10446602-post1.html ).

This is some great work. Even if this is something I could never afford to own I love seeing how people solve problems to build cars.

 Thank you! It's a really time-consuming process but I believe that the satisfaction of seeing the end result and driving the car once it's done is worth the effort. Cheers! :)

Porsche and VW/Audi stuff is the same, Audi parts from Europe are very cheap if you can get it shipped

This reminds me a lot of the transformation made by exomotive as their kits evolved. Particularly the custom cut tubes and alignment tabs. Slick. 

In reply to OHSCrifle :

 When it comes to tubular steel frames, CNC-laser cut tubes with tabs and holes are the way to go, especially when they are combined with laser cut jigs. They offer a great precision and ease of assembly prior to the welding process. Both are crucial for series production.

 Pictured below are some assembly instructions and laser cut tubes for my previous CAD project for an electric supercar that I started back in 2013. It would be nearly impossible to build it without the laser cutting and engraving of the metal tubes and plates, considering that it also needed more than 700 holes for rivet-nuts for installing the body panels, interior panels and various components.

 A couple more images showing the project from different perspectives.

 Some photos of the finished rolling chassis, less the engine and transmission. :)
