Detroit to offer integrated powertrain in 2015
Fleet Owner / May 22, 2014
A new integrated powertrain package – linking together a proprietary engine, automated transmission and axles – will be rolled out by the Detroit division of Daimler Trucks North America starting in January next year.
Initially available only for the Freightliner Cascadia Evolution Class 8 tractor and then later in 2015 for the Western Star 5700, Detroit’s new integrated powertrain combines a DD15 engine with a new “downspeed” rating of 400 hp and 1750 lb.-ft. of torque with the company’s DT12 automated transmission and axle products.
Brad Williamson, DTNA’s manager of engine and component marketing, told Fleet Owner by phone that two rear axle options will be offered with Detroit’s new integrated powertrain: a 6x2 rear axle configuration with a 2.28 ration and a non-driven tag axle on the tandem, reducing total weight by almost 400 lbs., along with a new 2.41 ratio 6x4 rear axle set up.
“To this point, we’ve offered each piece of powertrain separately; now we’re combining them into one package to maximize fuel economy, along with other benefits,” he said.
For example, Williamson pointed that by “tuning” transmission electronics and axle rations precisely to the DD15 engine calibrations “downspeeding” can now occur efficiently – meaning more engine torque can be made available at slower engine speeds of roughly 975 revolutions per minute (rpm) versus 1,050 rpm.
“This is something (downspeeding) that our competitors have offered for a while and now we’re able to offer it,” he said. “Basically, it is the ability to provide more torque at slower engine speeds and that helps save on fuel without compromising performance.”
Detroit’s DT12 transmission – equipped with what the company calls Intelligent Powertrain Management (IPM) – is what really will help drive further fuel economy savings, Williamson noted. By using pre-loaded terrain maps and global position system [GPS] location data to literally “see” the route ahead, the DT12 on cruise control can automatically adjust transmission and engine functions to save fuel while ensuring a smoother ride.
“This is something a driver simply cannot do, because they can’t see over the crest of a hill,” Williamson added. “By using pre-loaded maps and GPS, however, the DT12 can – so it will literally ‘know’ it can stay in 11th or 12th gear on a hill because it knows where the top is and how steep the grade is on the other side.”
In his view, the DT12 transmission is the "critical link" between the engine and the axles, and with the addition of the IPM feature, it provides a "seamless solution" that has a direct impact on fuel savings.
Williamson stressed that the other big benefit to DTNA customers from an integrated powertrain is that since all the components – engine, transmission, and axles – are built by one company, in this case Detroit, more detailed information can be shared between them and they can all be serviced at one location.
“That’s the ‘secret sauce’ if you will: we share all the available information between the components because, as I like to say, ‘they all speak Detroit,’” he explained. “We can also offer ‘one stop shop’ service as everything – the truck, engine, transmission, and axles – is ours. No more going over here to deal with an engine issue, over there for transmission service, with separate stops for axle work and truck maintenance thrown in as well.”
“We know exactly what our customers want: Leading technologies integrated from one source that allows the customer to easily implement into their business model and improve uptime, safety and efficiency,” noted David Hames, DTNA’s general manager of marketing and strategy, in a statement.
“We’re able accomplish the level of performance and efficiency the [new] integrated powertrain provides by designing, engineering, testing and manufacturing everything under one roof,” he added. “Every individual product was studied to make certain they were specifically tuned to work together to deliver maximum efficiency.”
Williamson also pointed out that Detroit is going to forgo the traditional “printed brochure” route and instead provide details on its new integrated powertrain through a new “Demand Detroit App” for both Android and iOS devices, which will be activated sometime in early June.
Kc thats just what I meant when I said if only D B would have bought Mack instead it would have (in my book anyway) a much better partnership! I think Mack America would have a lot more to say and do then they do now

It sounds to me like he used a soft steel? He needs to use well over 100,000 PSI steel on that frame. Hardened steel won't bow or bend like you said but it will crack! Find out what steel they usedthe old frame was cracked and took it to a shop, the cut it off in front of the front drive, replaced from there back and 4 days of running it, it now is bent out where the arm goes from the rear drive to the frame, and is also bowed down between the tandems under the 5th wheel plate.

If your lookin for the 8.25-20 2-piece rim I think they have been outlawed and then you had the Firestone split rim that was split from one side to the other an fit into a groove with a solid ring around the outside. They are both very dangerous rims and have been outlawed since the 60's I used to cut them with a torch when ever I came across one. I'm sure you know what your doin but I would stay away from anything from the junk yard

I have one with a V-12 RL700L at the time (1971) it was rated @ 475 hp mine is about 525 maybe? Your gonna have to move the cab back about 6" to squeez that baby in but it's gonna be well worth it!! It is by far one of the best engines ever made and not many will catch you if you are geared right, and they last for ever! There is nothin like the sound of a V12 or a V 8. Mack! Mack made a 6 " spacer between the cab an the hood and there is no cut away for the vent in the hood you also have to make room on the driver side for another air cleanerLooking to restore a 74' R700L. I've been going back and forth with my dad on which motor to put in it. I'm leaning to a V-8 Mack but my dad keeps saying he wants to put a V-12 detroit in it. Truck originally came with a V-8, but I was curious, was the v-12 detroit even an option in 74 or any other year for that matter?
