Question 300E 2.6 and 300E: Differences in engine?

300E 2.6 and 300E: Differences in engine?

Are both M103 engines, is one more reliable than the other, do they have the same issues, and is 2.6 a lot less powerful?

'92 300E
Thumbs up

I may not fully understand your question... but my w124 is a 300E period and not the 300E 2.6. and the only difference I know of the 2 is mine is a 3.0Liter engine, as the 300E 2.6 is a 2.6 Liter engine. Obviously, the 3.0L is going to have more power, but I have heard the 2.6L gets better gas mileage.

I hope that answers your question.

same engine family. obviously because they have differing displacement they arent the same engine. i think the bore sizes are different.

reliability is the same.

20 horsepower difference

260E , 1989 (for now)
Bore and stoke are different.
camshaft are different,
Fuel injection system have different settings/calibration,
Transmission are not the same,
rear-end ratio are not the same,
This is only a few of the differences.
