Mitsu doesn't have the financial power to rollout cars at the same speed as Hyundai does, but they'll get there.
Their focus is on small cars now and most likely we'll see the iCar and the new Colt long before the Galant, Endeavor or Eclipse replacements.
since mitsu is a huge conglomerate, if their auto sector fails, then their soy sauce, glass manufacturing, etc... can bail them out. mitsu does have the finances to improve their cars, but it will come at the expense of neglecting other, more profitable parts of their conglomerate. remember, mitsu and hyundai are very similar; both are huge conglomerates. hyundai also has divisions that deal with tourism, shipping freight, department stores and heavy industries.
as others have mentioned, mitsu is not on the radar of anyone. mitsu does not have a single offering that makes it into the top 3 of any segment....unless AWD, turbocharged, rally-inspired sport compact is a segment. seriously, would anyone speak of a lancer in the same breath as a civic, corolla or 3?
