Fuelly's response to my suggestion..
My suggestion: Under 2013 Ford Focus, you should add a filter, or engine class for the ST since it is a high performance turbocharged version that is rated at a lower MPG than the other trim levels for 2013. Right now the ST's are mixed in with others, skewing the data. Just a thought.
Fuelly's response: Thanks for the suggestion. We don't track vehicles past the model level and that's a blanket rule across all vehicles. There are
instances like this where it might be nice to track trim levels, but
with our small staff we need to have rules to keep things manageable.
Many people include details like this in the vehicle name. So
sometimes you can spot differences that way.
