I'm sure there was some issue but not catching something so major and obvious as fuel differences seems unlikely. That's almost as big as 50/60hz between the US and well.... most everywhere else.
At least I hope not, otherwise, I'm going to lose some serious faith in their engineering department(s). I'm thinking they've had a few glitches in the first pre-production batch that they ran back in September for QA purposes (the same ones making the car magazine circuit), and they're trying to make sure they've got these and any other as yet undiscovered glitches out of the system before they release them onto the general forum-happy public to avoid such popular title posts as "my-RAM-ED-is-DOA".
