in fact they made them from 1994-??, I just sold one a few months ago. Mine was the 1500 Z71 4x4 king cab with a 6.5 turbo diesel. The truck was strong, previos owner towed a goose neck horse trailer and I used it to tow my 272 Sportcraft. Most of these trucks ended up selling up north and Canada as they use them as snow plows

I was planning to buy one. It would be my first new truck. After talking with GM the last week over the phone, they told me that they are no longer planning to put the 4.5 Duramax into production :(


Diesels are fun to play with :thumbup: which is why I like having a diesel truck but, really don't need the 3/4 or 1 ton configurations.

they haven't put a diesel in the 1500 since they stopped making the 6.5. all the 1500HD's have the gas 6.0 and occasionally the 8.1 but the 8.1 and Duramax 6.6 have been only in the 3/4 and 1 ton since about '02 or '03. They looked hard at the 4.5 V-6 Duramax for the 1/2 ton and the Hummer's but I think that idea was discarded when the gob'ment bailed them out. I had an '03 and an '07 2500HD with the 6.6 and loved the engine even though the early models had a few injector issues but they made it right with a recall and extended the warranty on the injectors to 200k miles.

But Toyota diesels ain't installed in an American truck like the Isuzu engines... You would think Detroit Diesel could have came up with a motor on their own.

Because the 6.2 and 6.5 were indirect injection and weren't "powerhouses" like the Cummins. They were meant to be good reliable engines that got good mpg and could haul.

The following is from Wikipedia:
LMK

This engine is not yet commercially launched although it was touted in the automobile press as one of the most important new engine concepts for small trucks and SUVs by finally delivering a capable diesel engine in a compact enough package. The engine project is current on indefinite hold by GM. General Motors planned a 4.5 litre 72-degreehttp://en.wikipedia.org/wiki/Duramax_V8_engine#cite_note-7 V8 for light-duty applications which would be built at GM's powertrain facility in Tonawanda, New York after 2009. Designed to fit in the same space as a Chevrolet Small-Block engine, it is expected to produce over 310 bhp (230 kW) and 520 lb·ft (705 N·m) of torque. It added urea injection, 29,000-psi (2,000 bar) piezo-electric common-rail fuel system over previous Duramax architecture.http://en.wikipedia.org/wiki/Duramax_V8_engine#cite_note-8


It was initially targeted for the Chevy Silverado/GMC Sierra and Hummer H2.http://en.wikipedia.org/wiki/Duramax_V8_engine#cite_note-autoblog4.5-9 Unlike previous Duramax engines, the 4.5 liter is planned to be designed and built entirely by GM, without assistance from Isuzu.http://en.wikipedia.org/wiki/Duramax_V8_engine#cite_note-pickuptruck4.5-10


As of March 2009, a GM spokesperson stated the engine project has been put on an "indefinite hold" due to current economic conditions
