I understand that they solved all the problems with the earlier straight six in the 98-99 E300d models, and according to this gov.fuel economy site they got the best mileage http://www.fueleconomy.gov/feg/compx...esel&year=1999. And I know that a straight 6 engine is the best internally balanced design.

My question is did they make the wagon in a diesel too...I have been looking for one all over the internet.

If not I have been considering a 85 300TD.

 

thanks dude I guess thats why I couldn't find one.

Did they put the 2.5 liter in the 87 wagon?

I have read that the 2.5 was a good engine, there are so many diesels made by Mercedes its hard to understand. guess the 87 300TD was the less desirable om603 and if so are there any after market parts to resolve the head, and Cat. issues.

I have a 2002 golf TDI but would prefer a larger wagon thats why I have been checking out the Mercedes. I like the older 123 chassis, but I am looking to get the best MPG's possible. I also like the idea of the Simplicity of the 617 engine, but looking at the Gov Fuel economy sight. they are not as economical as the 98-99 e300's. Of all the wagons I like the W210 chassis.

Has anyone done a 606 diesel conversion in the 210 wagon.

Or performance mods for the 123 300td, and maybe a tranny swap with higher gears.

 

these are the best MPG figures on Fuel economy.org. but I am not sure how accurate they are.

http://www.fueleconomy.gov/feg/diesel.shtml......85 190 2.2, 4 Cyl

.http://www.fueleconomy.gov/feg/diesel.shtml....87 190d 2.5, 5 Cyl

http://www.fueleconomy.gov/feg/diesel.shtml.....98 E300 6 cyl

I am surprised at how close the MPG figures are on the 2.5 % cyl,and the 2.2 4 cyl, and even more surprised at the MPG's of the 3.0 6 cyl.

Unfortunately the 85 300td is low,
