I have a new 07 Sonata 4 cyl. This is agreat car and engine. Unfortunately, I understand that it will not run on E85 formulated fuel. What happens If I were to run E85? Is Hyundai doing anything to resolve this delima? Will there be kits made available that will solve the problem and maintain the warranty? I suspect that sometime in the near future, unless we wake up and complain, E85 will be the only fuel available, with it's poor performance and higher price.
