The "original", the Australian market Titan, looks so much better, without for example the tacky US market gray plastic fender extensions, chrome grille and headlamp trim, and front bumper. Volvo visibly decontented this truck for the US market.

I don't see a complaint with the splash guards on the fenders. I drove a 93 RW 713 that rubber splash guards from the factory that faded with time. The CL' s I drove all had big fender guards.  The ones on the titans look fine. There alot better than the huge ones on the granites that take up half the fender. 

I was talking to a guy from Michigan who has 5 titans. He's also pissed at mack. He said he's picked up some big jobs because of his titans . People want his trucks onow the job because they look rugged and strong. 

A sleeper option would have made the Titan a sales success. I go by the Mack dealer in Sioux Falls every couple weeks, and every South Dakota spec 4 axle tractor I've seen there had a sleeper. But 17 axle double trailer rigs running at over 75 tons gross weight are routine in South Dakota, and a 13 liter 505 HP engine just doesn't have the starting torque or HP to handle those weights. In a northern state where a blizzard can show up unannounced and strand your for days a sleeper is a necessity, and the lack of a sleeper doomed the Titan from the start.

Titans are rare in Michigan. But there are many RW 753 and CL 753 Michigan Specials still around. I drove a DM 800 with a 335 Cummins and moved Cat 235C's and D8K's in the 1990's. DM 800's like that were pulling 50 Ton trains at that time.  There are many GU 813's with 505's here also, pulling trains. But dropping the CL 700 was a mistake.  Titan needed more power choices, I think.

I think these will haul tanks like the Western Stars they have now.

Below is a picture of a broken down Star unit getting a tow.

Impressive. The M88 Herc weighs in a bit uder 155,000  pounds!

A 400 HP engine is plenty and even 300 HP will do the job at the U.S. federal maximum weight of 36 metric tons (80k pounds). But double that to the 75 ton or more weight of a Michigan train and 600 HP is needed and 700 HP would be preferred.

Not a bad place to be, Paul. In my observation nowadays too many people are generally in a big hurry but don't even know where they're going.

The problem is finding drivers that would drive a 300 or even 400 hp on longer steeper trips when there are oodles of 550 and 600 hp trucks running the same roads. I know of some companies that ran 400 and 427 macks and the drivers complained so much that the companies switched to other makes with 500 and 550 hp

It's going to be even more of a problem when electronic logs kick into effect. Guys try to make up their time while driving to counteract all the wasted time otherwise on-duty not driving.

We used to pull 63.5 tons with 12L 460hp Macks up here in Alberta. Right now I do the same thing with MP8.
From 63.5 to 75 tons you are looking at just over 10 tons difference. 600 hp isn't necessary let alone 700.
There's a difference between need and want.

First off, Mack underrated their engines, so a 460 HP Mack is pretty much the equal of a 505 HP Volvo. The measure of performance we need here is HP/Ton, for example the minimum requirement in the EU for decades has been at least 8HP per ton.  Using that formula at 63.5 tons the 505 HP Volvo engine is adequate, but using the same 8HP/Ton formula we need 600 HP at 75 tons. In terms of real world performance, years ago I did a regression analysis on dozens of Truck magazine road tests as they used the same route for every test and controlled well for other variables. I found that under 8HP/Ton performance measured in time to complete the route really fell off, performance pretty consistently improved as HP/ton increased up to 10HP/ton, and any increase above 10HP/Ton produced diminishing returns. This jives with research Cummins did around the same time that showed that at 33 tons performance improved in the flatlands when the truck was upgraded from an NH250 to an NTC350, but a KT450 improved performance little beyond that unless the truck was running in the mountains. 

So in conclusion, 8HP/Ton is adequate if your run flat roads with low speed limits, but 10HP/ton is better.
