GM 2.8L Duramax Diesel Brochure. Pretty in-depth.

For those interested in the GM 2.8 Duramax Diesel, here is a pretty nice in-depth brochure on it. Very much worth a look. Enjoy....

 

Cool. The exhaust brake will be a welcome feature. I drove a Toyota Land Cruiser Prado in Costa Rica with the 3.0L 1KD-FTV diesel. No throttle like on gasoline engines meant no engine braking when you downshift. Riding the brakes down the steep mountain roads was a bit unnerving (though the brakes held up OK and didn't fade).

Wonder what the reason is for the PCV heater. So the air from the crankcase is considered too cold to pipe into the intake directly?

Redline is at 4500 rpm?

 

It seems similar to a "jake brake" that big trucks have. Really excited about this motor- I can't wait to drive a Colorado with one.

 

Wow... Diesel engines are certainly developing in technology. I used to have a 96 dodge cummins and that was rated at 180hp & 420ft-Lb torque. And that was a 5.9L straight 6. 181hp/369ft-lb is pretty darn good for a 4 cyl. Of course the down side is all of the emissions items requiring use of DEF. I'd consider taking one for a test drive.

 

Rant warning . . . now, on the surface, who wouldn't want one of these?



But, I swear, the US auto industry just cannot do refined clean diesel right at all. After waiting for years to get a diesel in a "smaller" truck, the more I learn about the 2.8, the farther away I get. It has already been de-tuned from the initial 220HP/390lb.ft power targets because they decided to stick that weak 6L50 behind it that BTW is only rated for 330 lb.ft. And, this obviously precludes ANY ideas on an aftermarket performance boost as it will likely just destroy your tranny if the tranny even holds up to the stock torque.

And, BTW, you can only get the diesel in the 4 door, short bed so to hell with those of you who want an extended cab with a bed long enough to actually haul something.

The 3.0 V6 TDI Euro-diesel is an amazing power plant. Combined with 8 gears, an AWD 5000+ lb. SUV can get 35mpg and average 27-28mpg without difficulty. And slow? Stock tune gets you to 60 in 7 and, with a $525 performance tune, my Cayenne TDI could outrun about anything to 40 and hit 60 in 5.5 so diesels can run quite well when they are done right. With the particulate filter and 3rd catalyst stage it put out a cleaner exhaust signature than a comparable gas engine and was simply a delight to drive. Had I not gotten sick, I would still be happily driving it. Sold it and got the wife the S-Q5 Audi with the same TDI/tranny my Cayenne had. The wife just got 37mpg going uphill to Colorado and almost 40 coming back. And, smaller/lighter than the Cayenne, it will hit 60 in 6 with the stock tune.

And imagine that wonderful V8 TDI in a full size truck . . . ??

Jeep is blowing it too. Has anyone even seen ANY advertisements for the Grand Cherokee diesel? Has anyone even found one to test drive? What is not to like about a 31+mpg GC with all that torque? Nope, let's get the Hemi and get 21mpg.

Truly a shame as clean diesel is where all larger/heavier vehicles need to go. A Tacoma or Colorado or Canyon or Ranger or Frontier with the right clean diesel and drive train could easily push perhaps surpass 30mpg, could hit 60 in the 7 sec range without too much difficulty, and safely tow 7500 lbs.

Nope we keep putting V6 car engines in our pickups that struggle to get 23mpg and pull 4000 lbs. . . .

Think I'll just keep driving my old Gen 1 Taco. It won't outrun a thing and gets crappy mileage but it serves its purpose and it's paid for . . .
