WELCOME TO EM! I've been waiting for years for someone to Ecomod a 550 Spyder!!!

The following is very simplistic, but I think it shows what the possibilities could be :

Code:

    x constant / 3000 lbs = 46 MPG

=> x constant = 46 * 3000 = 138000 constant

Assume diesel engine adds 100 lbs => 1300 + 100 = 1400 lbs

=> 138000 constant / 1400 lbs = ? MPG
=> 138000 / 1400 = 98 MPG POSSIBLE(?!?!?!)

I'm not car mechanical smart, but as long as there is enough clearance, I would think it could be done. I am thinking the "normal" FWD layout of a TDI would interfere with the process (or just increase the cost of doing it). The mid-engine 550 was just a reverse-mounted boxer engine. I also think you could get even more MPG with a smaller displacement TDI engine from Europe. But maybe that would make things harder to to certify.

I edited your title to say "550 Spyder" instead of Pyder. I hope that's ok. I guess Pyder could be an "in the know" contraction of "Porsche + Spyder".
