Re: Freightliner Trucks Discussion Thread
They are. DRL stands for daytime running light, which means the light is always on when the vehicle is on. That's different than LED which stands for light emitting diode, which is a type of light bulb. The DRLs on the Cascadia are LED.

Re: Freightliner Trucks Discussion Thread
They are mandatory in Canada,i believe.But only for the trucks registered in Canada.If a truck registered in the US drive in Canada,but the truck has no DRL...i think it's not a problem.

Re: Freightliner Trucks Discussion Thread
DRLs are not a requirement in the US, which is why some new trucks such as the Mack Anthem and Western Star 49X don't have them. That's also why the stock Freightliner Cascadia headlights without DRLs are still legal as well.
Re: Freightliner Trucks Discussion Thread
Fuel efficiency problem:
Cummins efficiency engines are available for the Cascadia, too. I've tried them and was disappointed! While I have very good fuel efficiency with the Lonestar and the 49X while using the X15 efficiency, the Cascadia has about 1 mpg (and often more) less (500HP and 18 speed Eaton; comparable loads and routes provided). The Cascadia has excellent fuel mileage with DD engines and transmissions (especially the 400HP with the integrated transmission).
Has anyone got an idea, why this happens? Thanks!

Re: Freightliner Trucks Discussion Thread
Detroit is the official engine and transmission manufacturer for Freightliner. The truck was specifically designed to be the most optimal and efficient with those drivetrain components. While you can still spec a truck with Eaton transmissions and Cummins engines, it won't be as ideal if you're looking for fuel economy.
Re: Freightliner Trucks Discussion Thread
I don't think fuel efficiency is realistic in this game. Probably your weight or transmission effected the situation.
Re: Freightliner Trucks Discussion Thread
That is purely a marketing spiel to drive more sales of vertically integrated components to increase total revenue capture for the parent....there is very little (i.e. it is neglible) fuel economy difference in modern class 8 based on specific powertrains. The bigger impacts are on properly specing for the job and aero.supersobes wrote: ↑04 May 2021 13:59 Detroit is the official engine and transmission manufacturer for Freightliner.

The reality on their engine/trans combo is it is simply too early to tell what the net impact on TCO will be until these trucks go through a fleet cycle to understand resale values and maintenance costs over the cycle but there certainly is not a difference in fuel economy alone to justify their vertical solution vs competitive iron.
