Wow, those are some pretty significant differences. 15 hp vs. 20 hp? Why on earth would they do that? Did they happen to mention if there are also corresponding differences in the battery pack?
Why they would require 92 octane is also strange. And I always assumed that l/100km was the international standard. I guess that must have been an incorrect assumption...
DRL's only operate with high beams - well, there you go - a switch to turn them on and off!!
And the engine is rated at only 93 hp? Do they happen to mention at what rpm? Is there something about Mexican laws that would necessitate Honda underpowering the car, or is this somehow the normal HCH II, and they boosted the power for the American market? And the explanation you give for the performance when it is low on gas is just, well, strange....
