I will add photos once I get the required posts. any help appreciated  |
I suspect that VW has already 'optimized' the Passat's nose,respecting the 16-degree approach angle.(VW 'invented' optimization).
In 1976,the original Rabbit/Golf nose was withing 2% of an 'ideal' aero nose.
If your Passat was within 2% of the ideal,you could not expect more than a 1% improvement in mpg from a nose modification.
To get the 2%,I believe that you'd have to push the lower edge of the nose forward to at least get its face vertical,while maintaining an air dam which was as low as the bottom of the cars belly.
This would aggravate scrubbing on driveways,so the lower lip would have to be flexible.Here's kinda what you'd be looking for
