Thought some might find this interesting. Will be interesting to see how the
others respond in time.  Oh and I'm under the impression that VW isn't going
to produce a diesel next year due to the higher restrictions. Any truth to
that?

January 23 - Cummins Reveals Best-in-Class 2007 Turbo Diesel Engine 

CCN Publish January 23, 2007 

Strongest. Cleanest. Quietest 

WASHINGTON, D.C. (Jan. 23, 2007) - Cummins Inc. (NYSE:CMI) today unveiled
the strongest, cleanest, quietest best-in-class 2007 Cummins Turbo Diesel.
Leapfrogging the competition, the Cummins 6.7-liter Turbo Diesel engine,
used exclusively in Dodge Ram 2500 and 3500 Heavy Duty pickup trucks, has
increased displacement providing increased horsepower and torque while
achieving the world's lowest 2010 Environmental Protection Agency (EPA) NOx
standard a full three years ahead of the requirements. 

The new Turbo Diesel engines are in full production at the Cummins MidRange
Engine Plant in Columbus, Ind. Cummins has been the sole supplier of diesel
engines for the Dodge Ram since 1988, shipping approximately 160,000 engines
in 2006. 

Cummins is the first diesel engine manufacturer to have a product certified
to the 2010 EPA heavy-duty engine standards for oxides of nitrogen (NOx) and
particulate matter (PM) emissions, making it the cleanest heavy-duty diesel
engine available in North America. The 2010 EPA standards for NOx (0.2g) and
PM (0.01g) represent a more than 90 percent reduction in each pollutant,
compared to the 2004 standards. 

"The application of the right technology on the Dodge Ram is an extension of
the joint clean diesel development work Cummins and DaimlerChrysler have
performed together for nearly two decades," said Cummins President and Chief
Operating Officer Joe Loughrey. "The new best-in-class Cummins Turbo Diesel
and the Dodge Ram will provide the strongest, cleanest, quietest solution
for heavy-duty pickup truck customers." 

"This new technology is a significant validation of the industry's ability
to meet the EPA's 2010 clean diesel standards. These innovations help power
our economy and drive our environmental successes," said Bill Wehrum, EPA's
Acting Assistant Administrator for Air and Radiation. 

Cummins announced this news prior to the Washington Auto Show in conjunction
with DaimlerChrysler and the EPA. 

Strongest. The increased displacement of the 6.7-liter Turbo Diesel -
enabling an increase in horsepower and torque while maintaining fuel economy
- will provide Dodge Ram customers with better engine performance without
sacrificing the reliability and durability that have become synonymous with
Cummins. Increased vehicle control and lower operating cost are both
delivered on the new 6.7L Turbo Diesel with the addition of an integrated
exhaust brake option, providing outstanding braking performance. 

Cleanest. Combining advanced in-cylinder technologies, including a Bosch
flexible 1800-bar High Pressure Common Rail fuel system with Cummins
next-generation cooled Exhaust Gas Recirculation (EGR) and Variable Geometry
Turbocharger (VGTT), plus advanced exhaust aftertreatment technology, every
Dodge Ram pickup will comply with the 2010 NOx and PM emissions standards.
The advanced aftertreatment system includes a close-coupled diesel oxidation
catalyst, a NOx adsorber catalyst and a combined diesel
oxidation/particulate filter. The engine also incorporates a proprietary
closed crankcase ventilation (CCV) system to eliminate crankcase fumes and
"driveway drips." These advanced technologies require the use of Ultra-Low
Sulfur Diesel (ULSD) fuel in order to meet the tough 2007 and 2010
regulations. 

Quietest. The 2007 Cummins Turbo Diesel achieves a 50 percent noise
reduction over the previous model, even with the increase in power and
torque. The combination of reduced combustion noise, a low-noise VGT,
optimized fuel timing/delivery, reduced-noise accessory drive pulleys and
block side shields all contribute to this significant noise reduction. 

Since 1988, Cummins and Dodge have collaborated to ship over 1.5 million
Heavy Duty diesel pickup trucks and today enjoy around 30 percent market
share in this highly competitive market in North America.
