Detroit introduces fully integrated powertrain

Your sweet spot has moved a little to the left. Uptime has increased and integration is doing great things for your performance. Out of context, you’d wonder what kind of B movie you were watching. But not today.

Today, it’s all about the truck. On Thursday, May 22, Detroit introduced the fully integrated Detroit powertrain with proprietary products joined to provide seamless integration of the engine, transmission and axles.

The demand today is for high performance, excellent fuel economy, reliability and ease of use.
Owners look for weight reduction, more time on the road and less in the shop. Daimler says that’s what it’s striving to achieve across all of its brands from Freightliner to Detroit.

Daimler’s next big generation of integration is the new Integrated Detroit Powertrain (IDP). This integrates three specifically engineered Detroit components – the engine, transmission and axle. The goal is to create a system that is efficient, provides on-the-road performance and is reliable.

According to Daimler Trucks North America General Manager of Marketing and Strategy David Hames, Daimler’s internal goal of achieving 5-7 percent fuel economy improvement every two years was realized with the introduction of the Freightliner Cascadia Evolution. And that was before the DT12 Transmission and new 6x2 axle configurations were added.

If you keep stacking those 5-7 percent fuel economy increases together, you’ll quickly realize that 8 mpg fuel economy is not only realistic, it’s already happening.

In the quest for ever-improved fuel economy, Detroit has gone straight at the sweet spot. Longer gear ratios and lower operation speeds – downspeeding – doesn’t necessarily mean driving slower. But it does mean moving the power and torque curves to the left. So you can still drive 63 mph (or 65 or 75), but your rpm for the sweet spot (that magic place where your torque and power curves maximize your fuel economy) can be lower. That’s driving smarter even if you don’t slow down.

It’s not news that an automated transmission shortens the learning curve for inexperienced drivers and takes a little of the pressure off an experienced professional. Where it makes a much bigger impact is on the bottom line. Trucks that aren’t facing drive train issues due to operator miscues spend less time in the shop. And that’s money in the bank.

When it comes to money in the bank, Daimler’s approach to vertical integration also takes into account total cost of ownership. Not only how much you pay for the truck, but how productive the truck, with a clear focus on reducing downtime. And they point out that the real cost of ownership means keeping your money right where you want it – in your wallet.

Detroit’s put the whole package together. So when you’re ready to spec that new truck for yourself or your small or growing fleet; one stop shopping with real accountability and warranty may be as close as your fingertips.

That package will first be available for the Freightliner Cascadia Evolution in January and then all new Western Star 5700, which is coming later this year.

Available in early June to the customers and consumers, Demand Detroit’s new app will be available for your iProduct or Android. With a wealth of information about the features and benefits of the DD15 engine, DT12 transmission and axle configurations; you'll have 8 mpg in your headlights. For today, you can go to for the information you need.
