EPA Recognizes Dodge for Developing Cleanest Heavy-Duty Diesel Pickup Truck
New 2007 Dodge Ram 2500 and 3500 with Cummins 6,7-liter turbodiesel engine is first Chrysler Group BLUETEC vehicle and first to meet stringent 2010 truck emissions standards in all 50 states.
- 6.7-liter Cummins turbodiesel engine achieves 2010 NOx emission standards three years early, making it the cleanest and best-performing heavy-duty pickup truck in the market
- BLUETEC-equipped 2007 Dodge Ram Heavy Duty available in March, starting at $33,650 (includes destination)
- 2007 Dodge Ram Heavy Duty is the first Chrysler Group BLUETEC vehicle
- Breakthrough emissions technology along with the use of Ultra Low Sulfur Diesel (ULSD) enables "systems approach" to improve air quality
- Nitrogen oxide (NOx) emissions reduced by as much as 90 percent; particulate emissions virtually eliminated
- Diesel engines provide up to 30 percent better fuel economy when compared to equivalent gasoline engines
Today at the Washington (D.C.) Auto Show, the U.S. Environmental Protection Agency (EPA), together with the Department of Energy (DOE), Chrysler Group and Cummins, recognized the new 2007 Dodge Ram Heavy Duty as the cleanest mass-production diesel-engine pickup truck on the market.
Available in dealerships in March, the Dodge Ram Heavy Duty's 6.7-liter Cummins turbodiesel engine is the first to meet 2010 truck emissions standards in all 50 states, and will be significantly cleaner than other pickup trucks. It is the first BLUETEC vehicle from the Chrysler Group.
"This new technology is a significant validation of industry's ability to meet 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.
The new 2007 Dodge Ram Heavy Duty engine uses a diesel particulate filter (DPF) to virtually eliminate particulate matter emissions and an adsorber catalyst to reduce oxides of nitrogen (NOx) by as much as 90 percent.
"The Dodge Ram Heavy Duty pickup truck with the new 6.7-liter Cummins turbodiesel engine is the cleanest diesel truck available on the market," said Tom LaSorda, President and Chief Executive Officer, Chrysler Group. "Working together with Cummins, Dodge is the only manufacturer to meet stringent 2010 emissions standards -- today. That's great news for our Heavy Duty customers -- 80 percent of whom choose the diesel option."
Dodge Ram Heavy Duty trucks' long-standing relationship with Cummins was established in 1988 and continues to thrive with new, more powerful, more efficient and cleaner turbodiesel engines. In Indiana late last year, Cummins produced the 1.5-millionth diesel engine for the Dodge Ram.
"Partnerships like the one we have enjoyed with the DOE and the leadership shown by the EPA on ULSD have provided the right environment for this technological breakthrough," said Tim Solso, Cummins Chairman and CEO. "We continue to research and invest in technologies that ensure Dodge Ram heavy- duty trucks equipped with the Cummins turbodiesel engine are as clean as they are powerful."
Improved Emissions and Durability
In addition to the NOx adsorber and the DPF, the 6.7-liter turbodiesel engine includes other technologies to improve fuel efficiency and reduce unburned hydrocarbons.
- A cooled exhaust gas recirculation (EGR) system combines with a uniquely designed piston combustion bowl and a high-flow, electronically-controlled Variable Geometry Turbocharger (VGT(TM)), matching boost pressure with the engine's performance needs to reduce emissions and improve drivability
- Within the exhaust system, a self-cleaning DPF and an oxidation catalyst reduces particulate matter by a factor of 10. The emissions system is designed for a government-certified 120,000 miles
- A new closed crankcase ventilation system eliminates crankcase fumes and oil carry-over, a common problem with past diesels
