Hmmmmmm!!!! Very interesting.

But will it make the tree huggers happy?

[SnakeH2]

Do we want to make them happy

do you really care????

[wingnut2u]

It was just a rhetorical question, I was not expressing my views, hell I live in Texas, we do what we want and tell the rest to go screw themselves

[aggiehummer...er]

Just thought that previous post needed a "Hell Yes" of affirmation.

Damn, an article that is correct...not that I would know...

[wingnut2u]

I never thought I would say this to an Aggie, but thanks for the support

Dream on....

More Info:

Environmental benefits of the new engine include a 13-percent reduction in CO2 versus gasoline engines, and at least a 90-percent reduction in particulates and NOx compared to diesel vehicles today. This will be GM's first engine to use a NOx after-treatment system with a diesel particulate filter to help achieve the Tier 2 Bin 5 and LEV 2 emissions standards.

Technical highlights of the engine include aluminum cylinder heads with integrated manifolding, compacted graphite iron (CGI) block for a strong engine base and fracture-split main bearing caps and connecting rods for a precise fit. A high-pressure, common-rail fuel system is used, which has the ability to inject fuel five times per combustion event to control noise and emissions.

Phelan: GM's New Diesel is Powerful, Efficient
Detroit Free Press


By Mark Phelan


Aug. 25, 2006


If you peered over Charlie Freese's shoulder toward the horizon Thursday,
you just might have seen the future of the American muscle car. Or, at
least, the powerful and fuel-efficient diesel engine Cadillac needs if it's
ever going to be a major player in Europe .


Freese had just revealed the first tantalizing information about General
Motors Corp.'s 360-horsepower V8 turbodiesel, which will debut sometime
after 2009 ? probably 2010 or 2011 ? in a full-size pickup. Freese is the
automaker's executive director of diesel engineering.


Details are scanty, because GM is waiting to receive patents on some of the
engine's technology, but Freese promised it would meet emissions
requirements in all 50 states when it goes on sale. That's a significant
accomplishment. The United States will have the most stringent limits on
diesel emissions in the world in 2010.


Other automakers, primarily German brands with a century-plus history of
diesel development, have said they expect to be able to meet the
requirements, but they don't know how yet.


GM's figured it out, said Freese, but it's not telling anybody until the
ink dries on the last digit of the patents.


Here's what the rest of us know now:
GM promises the engine will use 25 percent less fuel than a
comparable gasoline V8.
GM developed the engine to match or beat the world's finest diesels
on power, fuel economy, sound and vibration. That makes it what
Freese calls a premium diesel, like the ones that power most luxury
sedans like the Audi A8, BMW 7-series and Mercedes-Benz S-class in
Germany.
The turbodiesel features high-pressure direct fuel injection, dual
overhead cams and four valves per cylinder.
GM developed it for use in a variety of vehicles, not just big
pickups.
The engine fits in several different families of GM vehicles.
It may be used in vehicles GM sells around the world.
It fits in the same engine compartment as GM's wildly successful
small-block gasoline V8, which powers everything from the Chevrolet
Corvette, Impala SS and Silverado full-size pickup to the Cadillac
Escalade luxury SUV and Pontiac GTO muscle coupe.
It will be smaller than the 6.6L Duramax V8 GM already builds for
heavy-duty versions of its big trucks.
Emissions of particulates and oxides of nitrogen will be at least 90
percent lower than current diesels. Carbon dioxide emissions will be
13 percent lower than from a comparable gasoline engine.


"Diesels are critical to GM," Freese told me this week. "Globally, diesels
are very much in demand," particularly in Europe, where they account for
about 50 percent of new car sales, and South Korea, where 90 percent of
SUVs roll out of the factory under diesel power. He expects diesel sales to
grow in other booming markets, particularly China .


Diesels haven't been much of a player in North America . They're used
primarily for tractor-trailers, work-oriented heavy-duty pickups and
agricultural and construction equipment.


GM was a leader in diesels once, but it lost that position through
inattention and eventually sold its Detroit Diesel unit, now owned by
DaimlerChrysler.


GM spent the better part of the last decade making up for those mistakes.
It builds more than one million diesels a year today. Its model line
stretches from a little 1.3-liter diesel that powers small cars in Europe
to the 6.6-liter Duramax V8. GM builds the Duramax in Moraine, Ohio , for
use in workhorse trucks like the GMC Topkick and Chevrolet Silverado HD.
Moraine built about 200,000 Duramax engines last year.


The engine will debut in a pickup because diesel's combination of power and
fuel economy is especially appealing in big, heavy vehicles. Diesel engines
cost more than gasoline power plants ? nobody will say exactly how much,
but $1,000 to $2,000 is a reasonable estimate ? but owners get a return on
their investment much quicker when a diesel is in vehicles with low fuel
economy, such as pickups and SUVs.


The new V8 will plug a gap in GM's diesel lineup between the 3.0-liter V6
it sells in European cars like the Opel Vectra and the Silverado HD
pickup's stump-pulling 6.6-liter Duramax.


GM's not saying where the new V8 will come from, but you can bet production
will be somewhere in North America and it will be used in high-end
vehicles.


That's why Freese is so adamant when he calls it a premium diesel.


"We benchmarked it against the finest diesels in the world," including the
smooth and powerful ones in top luxury sedans like the Mercedes S-class and
Audi A8, he said.


"Our engine needs to be the best," Freese said. "The alternative for North
American buyers is a gasoline engine. The owners of the vehicles that will
use the engine have never been exposed to a diesel, so the noise and
vibration need to approach the levels of gasoline engines."


And that opens the door for diesel muscle cars and Cadillacs.


Without a smooth and powerful diesel for cars like its STS sedan, Cadillac
is doomed to remain a marginal player in Europe , brand general manager Jim
Taylor told me earlier this week.


And imagine a 2010 Chevrolet Camaro with a 360-horsepower V8 and highway
fuel economy over 40 m.p.g. That's my guess on fuel economy, but it's not
unreasonable. It would make the nouveau muscle car appealing to many more
buyers, and give GM's corporate average fuel economy figures a boost from
an unexpected corner.


Freese told me the technologies in the V8 may be used in other engines, and
I know GM's Saturn brand is looking for fuel-efficient, low-emissions
diesels for some of its upcoming models.


The pickup truck is the start, but keep your eyes on the horizon. There's
more coming.
