Waiting on New Trucks thread.

Not sure who you’re referring to. I know turbo compound engines have been out a number of years and taking advantage of downspeeding has been going on for even longer. The compounding has allowed even further downspeeding of drivetrains. It wouldn’t be possible without that.

Not sure what your aim is with the second part. I bet you’d be blown away by the engineers, if you actually knew them. They’re comprised of “real world” intelligent people.

I maintained healthy relationships with the fleet, tractor, and trailer managers. I was intensely interested in what was going on, what they were up to, how things were improving, etc. I regularly wandered the shop bays, talking to techs, trying to learn more, etc. I regularly bought the entire shop pizza and sandwich platters for their lunch. As one of the highest mileage generating drivers, running 9+mpg, one of a few running west coast routes, every person in the transportation operations side of the business knew who I was. I still hold the highest 70hr mileage number for the company. I loved working there and gave them my all.

The oil pan isn’t structural. The composite construction is quieter and transfers less noise and resonance. I’d say it’s a pretty smart idea.

 

That thing was awesome! I saw one awhile back, as I was bouncing across Indiana I-70.

 

Where I worked had a tech change a head gasket. He used brake cleaner to clean the surfaces. Once together, he started the truck, which ignited the vapors in the crankcase, which blew off the oil pan. There was oil all over the shop, techs, boxes, everything. Don’t do that.

 

Seen they have a lot getting 10 plus on the that Scania but again slower area as well. They hug that gap better then US does from what I have seen.

 

Look at the new I believe A26 if I remember right. The new drive train coming out this year will be much better. I agree though they messed up bad before.

 

And that is what spawned my question about aerodynamics being directly proportional.

 

I was thinking 362, but I'm not sure.

 

Yes. And, they run very deep kingpin setbacks, single screws, and triaxle trailers. That’s something I’m very curious about. There has to be a reason. And, based on IG, all I need is a Scania and hot women will be chasing me down. Haha.

 

Most of the reason is the small areas they have to turn in. Seen a lot on them a few months back and that was the main reason for what they do. Also they have the weight in the right area of the rear wheels for traction in the winter time.

 

I believe the deep king pin settings, 3 axle trailers (set further forward under the trailer) and 2 axle tractors is more of a product of their length laws and off-track.
