As promised, I wanted to discuss how my Cascadia Evolution has attained the significant fuel mileage increase over my already stellar 2010 model Cascadia.

Freightliner is only claiming a 7% increase in fuel economy over the first-generation EPA 2010 Cascadia model and a 5% increase over the 2013 model with next-generation aerodynamic enhancements.



 Lifetime fuel mileage for my 2010 Cascadia Lifetime fuel mileage for my 2014 Cascadia evolution

My previous truck was a 2010 Cascadia powered by the DD15 455 HP @ 1800 RPM 1550/1750 lb-ft @ 1100 RPM.

The current truck I drive is a 2014 Cascadia Evolution and is already exceeding Freightliner’s claims of a 7% increase with a 7.4% increase in fuel economy. In my previous blog, I wanted to share with you the results of the three months of April as they were each very close to my normal everyday operating conditions. The results were 13.7% over 2011 and 10.9% over 2012.

Most likely, the first 7% increase on the 2014 Cascadia Evolution came from a wide range of areas. Any one of these items alone would be fairly insignificant, however when combined the impact is huge.








 In regards to fuel savings, the engine also plays a role in the first 7% of this fuel mileage savings. The Detroit DD15 has undergone an evolution of its own for 2014 to gain in both performance and economy. For example, new friction-optimized pistons reduce contact pressure associated with the oil control ring. This not only helps enhance fuel efficiency, it improves durability.

The new variable speed water pump controls flow and power consumption based upon engine speed and coolant temperatures. This reduces load on the engine.

They’ve also implemented a next generation Amplified Common Rail Fuel System (ACRS) with higher injector pressure for optimized combustion control.

Finally, the updated DD15 uses a patented asymmetric turbocharger, which offers proven performance while reducing mechanical complexity. Working in concert, all of these improvements help increase fuel economy to levels which I could have never imagined.








The Cascadia Evolution .... Winning the battle at the fuel pump!!!

My First 10

I did some checking with the engineers regarding your question about the transmission. 2 to 3 % for the direct drive and 1% for each 10% of eCoast time. . I have been recording eCoast time at around 16% so that would equate to 1.6% fuel economy savings for the eCoast feature of my transmission.So this would make a total of 4.6% improvement in fuel economy.

I notice no mention of the transmission; any estimate of how much (if any) improvement comes from e-coast?

Henry has the "Total Package" for sure and he gets every drop of fuel mileage he can out of his set up. Great Job Henry keep giving us tips on how all of us can improve.

Got me James-still new though and I have been consistently well over 8 my best is 8.71-we really need to aero up these trailers

Very impressive! Best I've done so far is 8.8 on a 2013 Cascadia, DD15 std 10 speed & super singles. Hope to continue hearing about MPG. Thanks
