Mack Trucks Discussion Thread

As far as I know, Australia emission rules are similar to Euro 5, while the European 530 HP MX13 is an Euro 6 complaint engine. Might explain the difference.

Yeah, I figured as much.

The US emssions laws are not worse or better, but rather different. Focuses on different things. But all that matters little when the trucking industry has been using that loop hole for many years now, 10 - 12 years? maybe... to get around it and built probably millions of gliderkits. That seem to be more or less dying now unless something changes soon. They cant build more gliderkits at large scales anymore, you can still do it in your barn at home tho. But not for long.
But the way things are going in the US... who knows... not even sure the rules set a year or 3 ago, cant recall... still applies.. xD

The MX13 510, 530 and our 460 and 550 are all the same engine. Same internals, same injectors, same everything ... it's just the computer program (map) that is different.

Same as the Cummins X15 485 and 600. One can buy a Cummins 485 and then have the 600 'map' put into the computer and you have a 600hp X15.

Many operators down here option the X15 600 (or even the 580) and then after they have 'run them in' (usually around the 100,000km mark) will have the computer re-mapped to 610-620hp. What's more, Cummins Australia will still cover the engine under full warranty @ 620hp. Go over that however and you're on your own.

European emissions regulations focus on the CO/CO2 emissions, while USA regulations focus on the NOx if I recall correctly.

As those gases are generated in different amounts depending on the working profile of the engine (more or less oxygen, compression, fuel, ignition temperature...); same base engines are tweaked to behave a little different in its working profile in different markets to lower the emissions more sensitive on there. That causes the rated HP of the truck to change too between those different working profiles.

Also, sometimes it's a matter of resilience. An engine could be tampered to give more HP but at the price of less durability under certain work scenarios. US, Europe and Australian markets are very different not only in regulations but also in the kind of roads and jobs the trucks will have to endure. Companies test that, apply their maths and decide the average HP they can squeeze of an engine that will work in the "average duty" on those markets while preserving the desired level of resilience.

A lot of the new imports (Scania, DAF, Merc, etc.) are now Euro 6. The X15's are still e5 specs though. Not sure with the MX13's, as I'm sure KW Aust (Paccar) gets them from DAF.

Mack was in the game from the start. But only like AI model and had no name, everyone know it's Mack.

Yeah the front grille and the mud flap gives it away. I am glad Mack Trucks hasn't said anything. What if.......just what if branding comes along with the Anthem for the cement truck as well.

[Marcello Julio]

Nobody has commented on this subject here in this thread, I'm impressed
Well, Anthem is coming

Lol. Perhaps because we all been in the ATS teaser thread or the SCS discussion thread. But yeah, it does make the most since in here after all.

So anyone with me for it coming this week? Obviously if 1.37 doesn't go live, we won't get the Anthem. I am waiting for SCS to post a stream date. Otherwise, they will just post 1.37 ending and with it, comes the Anthem. 2 more brands to go in ATS.

[dk00?]

I say there's a good chance it's this week.
