I'm always coming across mistakes like this, and have mentioned it before. Every car i've driven in real life that is in this game has been wrong. The handling characteristics, the basic statistics and stuff like incorrect rev limiters and gear ratios. All of this information is easily and freely available from various sources on the internet as well as the car manufacturers themselves.
The bit that annoys me though, is that someone has created the car then said yes, that is okay and finished. Someone else has come along, probably quality control, who has gone over the data and said yes, this is all correct. Then a game developer/tester has tried out the car, and apparently has had no issue whatsoever. How could someone not notice the incorrect gear ratios on the Focus? Which means you have to ask, are they even bothering to go through these basic processes? Do the people who are involved in making this game actually like cars? Do they know what they are doing? Do they even have any interest in any of this? If Ford treated their cars with such a lack of detail, they'd be bankrupt within a year.....
