Damn that’s slow, my daughters 240D does the quarter mile in 19 seconds at 58mph.

At a steady 40mph then move to 60mph in its final gear and warmed up .No a/c .A new change of events for the 85 turbo 300d ,having some defined trannie issues ,acting up as of this morning with slow forward movement .It maybe a trannie issue.Ill report back when I have more info ,wont be able to get underneath it til mon.

It was during the drive home last night ,during around 50 mph it felt like it lost drive power for just a short second then regained .This morning jumped in it and the drive is real slow .Ill have more to go on in a few days.

I find the same behavior you do. The OM603 will wind up a bit more than the 617, so it'll keep pulling until ~4000 RPM or so then starts running out of breath. I have my bowden cable adjusted so that my shiftpoints at WOT are ~4300RPM and gives a nice driving experience, it drives about like a gas car.

When I ran the acceleration tests above, I got to 40mph, then held that speed for several seconds, then accelerated to 60. If I just started counting during an acceleration from 0-60 and began the count at 40, it would be about half the time since the turbo is already spooled and the engine is already at max power.

If I tried to go from 40-60 without downshifting to 3rd I’m not sure I’d ever get there.

Interesting.
Last night I adjusted the throttle linkage and checked for vacuum leaks - had a slow one at the 5-way plug into the thingy on the valve cover so I disconnected the EGR and ran two separate lines in/out of it, and reset the Bowden cable to 0 (just until all the slack is out at idle) along with a small tweak of the linkage, and my hard 1-2 and slipping 2-3 shifts are much improved. After I adjust the valves and check timing chain stretch I'll feel better about running it up there enough to set the shifts points as you describe and see how it feels.

It maybe the b2 piston at fault here. No forward but have reverse .Was lucky and didnt get caught on the open road. Might try this repair ,wasnt looking for a car problem so close to christmas though .Its funny that a 300sd I owned had the same exact symptom ,acted like it slipped out of gear briefly the regained ,was able to drive it home but failed the next morning ,didnt realize til that morning I had a problem .If your 40 to 60 mph is slow you might have an upcoming problem like this one!

Around 7 seconds, in an old dashcam vid I had trying to pass an inattentive motorist. So this was at 4th gear and with AC.

The bike will do it in about 1 second in first gear. I'm going to try timing it in the car. The seven second figure some have tossed about sounds right.

Edit: I got to do some testing on the back roads today. Leaving it in third gear, I get 40-60 in 8 seconds. Starting the run in 2nd and upshifting at the top of the second dot got me 6 seconds. I did a timed 0-60 run of 14 seconds, but I bogged it pretty badly on the launch, so I probably cost myself at least a second.
