Looks promising! 300hp 7L engine with no urea injection to worry about with the new emissions, and able to be upfitted in several ways.

That is very interesting. I'll be curious how they price it.

The way I heard it, Navistar was having Cat make the 15L block that they then put their fuel system and AEGR on. Gives Navistar a big boy for the OTR class 8 crowd, and compliments their existing MaxxForce engine line, which are all in-house designed and produced.

apparently the maxforce 7 is the same engine that was formally made famous as the powerstroke.

Nope. Cat has gotten totally out of the engine business for on-highway trucks.
Their last series of engines for big trucks was a total disaster. The Peterbilt factory here in town, had many trucks with failed Cat engines, hauled back to the factory, and retrofitted them with Cummins engines. All this was under warranty, and Cat had to eat most, if not all the cost. Cat threw in the towel on truck engines for highway use.

I read that and I like the line 'it will sell at a premium', just what the market needs - another over priced truck.:rolleyes: I thought the Ford or Dodge was overpriced.

In another article it sounds like four wheel drive is coming and a six speed automatic.

i would have liked to have seen them use the 2350 allison as well. the engine is definitly a deal breaker for me on one.

I'd love to have one of these trucks, but I can guarantee it won't be cheap compared to a Ford f-450 or 550. Looks to me like International is going after some of Ford's business now that their partnership is over. It's a nice way to use all those 6.4 engines as well now that Ford doesn't need them.

If the engine is the same as last years 6.4 liter powerstroke, I wouldn't want one because of the terrible fuel mileage. A friend of mine had a 2008 f350 with the 6.4 it got 11 mpg in pickup form unloaded and about 7mpg with a 16ft. landscape trailer with one mower on it.

CAT is NOT OUT!! Cat and Navistar are building an engine. The 15L CAT Engine will be rebranded MaxxForce for 2010 . How do I know?? My Brother Works for Navistar and He is Testing the engine as we speek.

The only Reason I would not buy that is because of the 6.4L..What a shitty Engine!!!

Now if it had a cummins I would buy it!

After I posted yesterday, I went to the MaxxForce (http://maxxforce.com/) website. There's no mention of anything bigger than the MaxxForce13, so I'd have to agree with you. Must be they couldn't reach an agreement for whatever reason.

I'm not sure but I'm under the impression that there are some differences. The block and heads(?) are the same, but the fuel delivery system is different. Also, the PS uses a DPF, while the MaxxForce uses AEGR.

I think being that Ford has nothing to do with this 6.4. it may be alright.

It looks like a CXT or MXT with smaller wheels and tires and just a cab and chassis model, so you can put whatever bed on it you want. IF its close to those models in price, nobody will be able to afford one anyway.

Here is what I have heard and read. Cat is no longer involved in designing or producing diesels for highway use. Cat will launch a new line of heavy duty construction trucks under tha "Cat" name. These trucks will be built by Navistar to Cat specs. at the Navistar plant in Garland Texas. This is the old Marnon factory where Navistar builds heavy duty, mixer chassis trucks.
Cat and Navistar may have some working agreement on the design of the engine for those trucks, but, Cat will not build them and they are Navistar engines. I think kind of like the agreement Ford had with Navistar on the Powerstroke engines.

What ever happened to the deal CAT supposedly had with one of the big 3 to put a CAT diesel in a full size pickup truck? That would sell like freaking crazy if they offered that! I never did hear what brand they were working with though, but I guess its not going to happen now after reading the post above? Too bad!

I tell you one thing i like international trucks but the one i have a 2004 international 4300 series is an ELECTRICAL NIGHTMARE. I just had it out with them the other day on recalls that i never received. I have mostly ford f-650 and 750s with cat engines and now after reading there not offering this engine anymore i feel like im going to get screwed with them in my trucks. I hope they hold up well. But that terrastar looks nice I would def take another look at international because they SUPPOSEDLY have no more electrical gremlins. I sure hope they changed those god dam mirror brackets all they do is shake when your driving down the road

As far as I know, the block design for the Maxxforce 13 was bought from Cat and then went and made their changes to it- DPF/DOC, all that EGR crap. The Maxxforce 7 is pretty much an updated version of either a 365 or 275 international motor, I'm not sure exactly. Kind of like the Maxxforce DT/9/10 are based off the 466 block. (All this is what I learned/was told while working at an International Dealership during my second year of Tech School- Diesel Mechanic)

I believe the 15L idea was thrown out there to see how much interest there would be, but with how terrible the 13's were/are I think they decided to throw it out the window. One thing about any of the international engines is the recalibratoins /DOC cleanings/ and recalls that need to be done it can cause some down time, depending obviously on your ability to get it to the shop when you're not using it.

School buses for example, a company in town has all IH buses, there was one week where all I did for 8 hrs/4 days was recalibrate ECMs, then run a DOC cleaning.

The maxxforce 7 which is in the terrastars was one of the motors where they required an engine update and a cleaning.

Enough of my rant, I think everything past the flywheel is solid in those trucks, in front of the flywheel I have my doubts. I wasn't around there long enough to see how well the new ones they sold held up.

The 15l is a cat block and gear train, the 11&13s are made by MANN out of germany, the maxxforce DT,9&10 are a 466&570. The 7 is the new VT365. The 275the was a v6.

Well, this thread started a few years ago. Any updates on opinions of the TerraStar Maxforce7. I've been in the market for a truck, and these seem to be a little less expensive than the competition, and with more horsepower 300 vs 220 in some of the Isuzu, and Hino, vs Ford & Dodge. I don't want a Ford, never wanted a Dodge, but I'd now consider it because they probably have the best engine, except there's no Dodge dealers that seem to deal in 450's 550's

CLARK LAWN
08-19-2013, 11:24 PM
I would go with a DT not a 7. But you would have to step up from a terrastar to a durastar. Only thing the 7s are any good in is school buses. They just don't have the torque to run anything heavy and end up getting the snot run out of them.

Source please. I see where the Durastar will be available with the Cummins 6.7, and where all MaxxForce engines will get Cummins SPF system, but no mention of any Cummins for the Terrastar.

Seriously, it would be nice to read more about this when/if you can release it, such as which model & specs.

I don't think that working for an International dealer gets you better information. I know that the salesmen that I have talked to don't know as much as I do about their trucks

I researched it and it is even said the terrastar will NOT be getting a Cummins due to packaging issues... at least not a isb, will it be a isv? maybe???

With the success that Navistar has had since the announcement of the return of Cummins to pretty much all there line i would think the Terrastar will probably follow. I read in HDT mag that Durastar sales increased by 22% fairly shortly after revealing it could be ordered with a Cummins. Not choosing the SCR [DEF] emissions type has been a nitemare for Navistar. Their new head comes from Pete so maybe we will see some improvements that have been long needed.

The nightmare was caused by the feds attempting to force technology that just wasn't up to the task. Had they not stuck their noses where it arguably didn't belong, there never would have been an issue. Then, they stacked the deck heavily in favor of DEF. The truly sad part is that the feds forced all the eggs into cummins' basket, thereby effectively creating a monopoly where we, the consumers, lose.

I beg to disagree partly. It seems when new regs are sought by feds they consult with manufacturers first to see what is doable and the makers have a part in the decisions. We have operated diesels for more than 50 years and there is a lot of profit in doubling the price of a truck engine and blaming the gov. The SCR/DEF technology has been used in Europe for some time and does well. No one has ever been happy in our part of the country with DPF . SCR allows for a less invasive exhaust the DEF is just urea and can be bought here for as little as $2.79 a gallon. Most trucks use very little in comparison to the extra fuel and down time DPF systems have.
