I think I found the weight of the Panhard LM64 correct me if I am wrong because the site is in French and I am not so up to speed on that language but it stated a weight of 570kg or 1256lbs!
Here is the link to the page =
Panhard CD LM 64 : LA ROUTE NOUS APPARTIENT!
With a weight of 1,256lbs and cd of 0.13 the Panhard is a pretty good representation of what I am aiming for with the Tigon. I am hoping with the Tigon I will be able to get to 1,000lbs which if I was going diesel only I definitely think I can get there but its going to be really tough in a hybrid version. I am all ready at 706lbs so there is not much wiggle room with the hybrid.
