There's nothing wrong--your 190E 2.6 auto does not have an

overdrive. The transmission's top (4th) gear is a 1.00:1 ratio. The

2.6 cruises at 2900-3000 rpm at 60 mph naturally. You still should

be getting around 28 mpg. There are 5sp-manual conversions, and you

may even be able to convert to a later Mercedes 5sp automatic with

some work, which would certainly lower your cruising speed rpm.

This would probably end up being cost-prohibitive, however.
