Hi fellow ecomodders !
I have had my CR-Z for almost a year now and it has been a blast so far and I think I have reached somewhat of a plateau in terms of efficiency. I mainly use neutral coasting (engine ON), DFCO and DWL as techniques to boost my mileage and seems to be working since my tank average is sitting at 45-48 MPG consistently.
I am currently working on an arduino-based active grille block. It is somewhat functional but it still requires a few tweaks, especially if I want it to survive through our harsh Winter months.
I am also working on redesigning the front fascia and bumper to clean up the aerodynamics. To do so, I have created foam blocks inserts (same approach as the ones on my Toyota Echo). This project is also far from being completed.
Last, but not least, I want to build some sort of Kammtail extension/cavity box at the rear of the CR-Z since I know the big efficiency gains are there. This is where I need input from you guys/gals. My objective here is to extend the kammtail by a fair amount, maybe 10-15 inches MAX, rear visibility being the key factor. I want this design to make use of the existing, albeit primitive, rear diffuser.
Let me know what you guys think ! I shall post updates on the progress of each mod.
Cheers.
