Perhaps I should pay better attention...had not heard the last one was already off the assembly line ... :o

That is a bit of a surprise. I thought the SERIES 60 had already gone the way of the square wheel and 8 track at least in automotive applications.
The 60 series has been gone for automotive use for a while now MTU has phased it out for Marine and industrial use now only German made engines and the old 2 strokes, the DD13 is leaving for German designed engines made in the USA so they say
I got to sit in on a DDC training class for the Guild members before the S60 came out. Later, I toured the new addition of the Redford engine plant that was still under construction for the 60, even as the first units were being built. Some things that amazed me were the system that torqued all the head bolts at once, the electric tracks in the floor that automatically moved the engines through the plant, and the robots that painted the engines. My company hauled all the Detroit parts and engines from MI to the distributor for OR and WA for 12 years so I got to see a lot of cool iron. Series 60, the best engine ever built, IMHO.
I would agree that it was a good tough engine even though I'm a longtime CUMMINS stock holder so I say this coughing. :)
All kidding aside, at the time DETROIT was new at 4 cycle engines in the heavy duty range at the time this engine was rolled out so for first timers, they did a good job. They had the 4 cycle 8.2 that was introduced in 1980 but from many accounts it stunk. Let's not forget that the SERIES 60 was the foundation for the SERIES 50 which was a 4 cylinder version(2 cylinders cut off the block. It was popular though in a bus, you had to live with the extra vibration that you can't really get around with that design. But if you can get past that, alot of people like it. I guess the EPA was a contributing factor in it's downfall plus the six cylinder designs from CUMMINS gave them an edge in buses being much smoother running.
That's a marine engine pictured-no air compressor and a water cooled rear mounted turbo.
And no EGR.

"Series 60, the best engine ever built, IMHO".
I really like hearing that Mark
I had a 1995 pre EGR S60 with 7 speed manual Eaton-Fuller in the D3 of the hockey team's. Great engine! So much torque! Go up the hills with the cars. The sound of it though is quite awful, being used to the sweet old 2 stokes... And vibrates at idle.

I went to MTU site, and they are still listing the S60 in both 12.7 and 14.0 liter. It would really get me scratching my head if they cancelled the Series 60. Good Luck, TomC
Has MTU ever reached Tier 4 with the 60 series last I read the 12.7 was tier 2 and the 14L was tier 3,I am trying to find the phase out that published a couple years back but who knows it may be renumbered like 1560 to match there others,but I did read where it was gone.
I am surprised how fast the 60 series reached 1 million the old 2 strokes never reached that mile stone till 1965
I'm glad someone else mentioned the vibration. Amazes me that my 6v92 runs so much smoother than the series 60 or 50.

You can stop the vibration on the 50 and 60 series just tap the cruise control and add rpm to idle then they smooth out if they have the right engine mounts
in my experience v engines run smother than inlines in general , big or small. I am a bike guy and love my v4 s for smoothness.
Slight difference between a bike engine and a 14 liter Diesel engine.
I checked with my Freightliner factory rep. And yes, the Series 60 is history on all fronts. Factory Reliabilts will be made for years to come. But new engines are no longer made. Good Luck, TomC
very true but look at a ford 300 6 inline and 302v8 which is smoother . Engines design come with inherent traits ,horsepower torque smoothness. Hard to get the best of all those in one design .Packaging of said qualities is also a factor.

So true. Some transit agencys repowered their buses with CUMMINS ISL's that originally had the DETROIT SERIES 50 because of smoothness issues. I can personally testify how great the old FORD 300 6 was. My previous work van had one and it was great. It was great for around town and fairly smooth running too, But, if I would have bought that van as a personal vehicle, I would have chosen the 302 V8 just for the overall improved smoothness over the 6 and that nice V8 grumble. It'll be interesting how these new ECOBOOST engines hold up over time with FORD. You can only get one V8 on the new F150 now and the EXPEDITON doesn't even offer a V8 now just the 3.5L V6 ECOBOOST. Oh well.
It's the 2 stroke design the 6L71 DDEC is as smooth as any V6 or V8 the 903 Cummins V8 will shake the bed sheets off the bed in a bus so will the 3208 Cat.I never heard of Transits replacing the diesel 50 with Cuminns but they did replace the 50 CNG with the Cummins CNG model the 50 CNG was a dog
That surprises me about the CAT 3208. Here in Milwaukee, our transit system had some small GILLIG buses back in the 1990's with the 3208 and those engines were as smooth as glass and as quiet as a V8 gasoline engine. I don't know what the problem was with the CUMMINS 903 in being so rough for a V8 but those were generally regarded as stinker engines in buses anyway with bigger problems.
Some Canadian transit agency repowered their buses that had the S50's with CUMMINS ISL's but I lost that link. I think we can all agree but DETROIT 2 cycles being the smoothest of all. I do love the description that someone applied "Swarm of bees in spam can." :)
Hi All, I've always had F250s with V8s, 460s, 390s, 352 and a 5.4 ltr, 1st year of the modular engine, Triton, it was a factory CNG dedicated, not dual fuel, powerful, smooth, decent fuel milage, liked it, except it spit out spark plugs! Ford wanted $2500 to fix it, how did ford get away with this, my mechanic repaired it for $250, with a modern version of a helicoil, next spit spark plug was $625, from a different shop, by the time the third ones simptons appeared I had enough, how could such a great truck have such a huge flaw, sold it and got an old 300 straight 6, great truck engine, a little thirsty, but no spitting spark plugs, lvmci...
Yeah those early FORD V8 and V10 engines had that problem but that issue was long corrected. Sadly, such a thing can burn someone for a long time on a product. Makes you wonder how they could have missed that one back about nearly 20 years ago when they rolled out that engine line.
You wonder if they will still produce these engines as they did with the 8V92 2 strokes for the military. Still might make them (8V92's) for the fighting guys. Sounds like the Series 60 will be a pretty tough engine to replace.
They haven't cast any new blocks for the 8V92 series in 5 years they just make parts and sell the re con engines plus sell the few new ones left, try buying a new head for a 8V92 none to be had according to WW William only a re con same with DD crank only aftermarkets are available.
Interstate/ McBee has taken over the Relaiblit line they run the plant in Utah now DD has nothing to do with anylonger
Yeah, That's what scares me on my 8V92 that is it's going to crash long before the coach does. Only have 76,000 miles on it now but still worried.
