That is accurate.
I want to add to it a little,
The Daimler group is hell bent for leather to create a proprietary truck.
Trucks have been built with vendor components (with the exception of Mack and IH years back, but even they folded and offered other components to satisfy big truck and rental fleets) for an eternity, it is one of the reasons that finding good Heavy Duty People is next to impossible. There are so many variations in specs that it boggles the mind.
We have to live and breathe this stuff in order to support it.
Trailers are still out way there, many times we crawl under the trailer to identify brake valves, suspensions, etc. There are just too many options.
Back to Daimler. They have a vision of a truck with all Daimler owned components. In the medium duty line they succeeded with the MBE900 engine, a six-speed manual gearbox and an Alliance rear axle. Offered the powertrain with a Mega-discount and extended warranty so they got some out and on the road.
Class 8 trucks are not there quite yet.
Detroit Diesel was purchased with the above mentioned vision of Daimler in mind.
Penske had already gone in and cleaned house at the Detroit Diesel engine plant in 1987. Too many people were not doing their jobs, there was no accountability for sloppy assembly and it was driving the reputation of the then current 71 and 92 series right into the ground.
He saw the need for the SERIES 60 which was on the drawing board at that time and got some produced and into some test fleet trucks. The fleets had strict orders to report any failures to Detroit, who in turn would ship out another engine. The customer was to simply swap engines and return the failed unit to Detroit. That way the engineers had un-molested evidence to help identify failed parts.
It worked well and helped pioneer an engine with the above mentioned production run of 1,000,000 plus units. They are still being assembled by hand for the Mexican and marine markets up until next year.
Now the emissions standards have sent the SERIES 60 to the grave, it simply can't handle the EGR and related hang on crap to be clean enough.
The DD series engines were designed from the start to be clean enough to handle the current and upcoming emissions laws with relative ease.
The DD15 was first out of the gate, now there is a DD13 available.
They are trying to get a C7 size out, that should hit the road in a couple of years.
That indicates to me that the current Mid-Size Cummins offerings in the Freightliner trucks is a short term thing. This is one of the issues that continues to create tension between Daimler and Cummins.
The MBE900 and MBE4000 series were an attempt to inject some German technology into the US marketplace, the 900 were not too bad but you could not give me a 4000 series. They are now history again due to emissions.
The DD15 and DD13 series have been quite reliable so far, time will tell. They are based on a global platform so if they will stay together you will see them in everything as time goes on.
