(August 24, 2006) — GM Powertrain's powerful Duramax 6.6L V-8 turbo-diesel engine is revised to meet new, stringent 2007 federal emissions regulations and continues to deliver the outstanding power and torque ratings customers expect.
Upgrades to the engine and a new diesel particulate filter system help ensure the engine meets government-mandated emissions regulations for diesel engines manufactured beginning in January 2007, which require a 90-percent reduction in particulate matter and 50-percent reduction in NOx.

"Maintaining power and torque leadership with the Duramax is important to us because it's the benchmark that built the engine's class-leading reputation with our customers," said Charlie Freese, executive director, GM Powertrain Diesel Engineering.

doesn't this require that special diesel??? older motors can run both "today's" diesel and the newer lower emmission diesel, but these new motors require the special fuel to properly run?

All the 2007 diesel motors (including Dodge and Ford) will require the new diesel fuel.

The "new" diesel fuel is merely low sulphur fuel, that's all. There's also an issue coming up with older diesels running newer fuel in that there's not enough lubricity in the fuel (harder on the pump, injectors, cylinders, ect) and its causing fuel leaks (kinda like switching to synthetic oil in an older vehicle, the seals give out). All while consuming more fuel to make the same power as before because the new diesel fuels don't have the same level of BTUs available as before...

Not to say I don't support lowing emissions, but at what cost? Its harder on engines and we're burning more fuel than before...

At my work we switched over to low sulphur fuel and every cummins motor had been in and out of the shop with fuel issues.

The internationls on the other hand have had no such issues.
