Rousch has been working for EM for almost 3 years? Curious question after reading your link. It states that EM has decided to bring Rousch on board as a partner along with the rest of their world class partners, but can you link that Rousch has actually contracted and accomplished engineering work for EM, or is Rousch waiting on EM’s funding like all the other partners?
Roush was contracted for engineering work. That's what they do. So finding proof that they redesigned a widget on the car is impossible. I do know this. Elio raised $16M in Reg A+. Right after that, Roush is announced at an engineering supplier. After that, Elio gets a new body and chassis along with suspension changes (which you can see if you look). Doesn't it seem to be a coincidence that all of that happened that way?
As for now, the MoU is with the powertrain manufacturer, not Roush. Roush is only there to see what will work and what will not. Then do exploratory work to determine what it will take to put that powertrain in the car. If you notice, Elio gets $2.5M and a few months later this MoU is announced. A coincidence? I think not.
After this, Roush will then fit the new engine and do testing to make sure it works. That will not happen until Elio raises more money. As Paul has said in the past about the money that they get, they burn through it right away. I bet that $2.5M was gone in about a month. Also, Roush works for money. No money, no work. They do not feel sorry for Elio. It's just all business. Plus Roush would not allow Elio to use their name unless they were getting paid and doing actual work.
