Is that a fact on the Elio? If so, would that mean shifting on mountain highways?
No, not a fact. I said “Just a guess...”
I have scoured the net, both Elio and technical websites. Nowhere is the final drive mentioned. In fact the only reference to gears is that you can have manual or auto five speed. (With five speeds, 5th gear is normally an overdrive.)
You couldn’t sell me one of these things unless it had a mower deck on it.
My motorcycle has a bigger motor and I think it’s too small.
Is there some sort of vehicle that doesn't downshift going up mountain highways? Maybe "mountain" means something different to you.
