MB is offering Bluetec engine for '07 in the E3320 CDI sedan and not in the R320 CDI or the ML320 CDI vehicles. The only difference is the exhaust system that uses the AdBlue techonology that if approved by EPA and CARB will make them 50 state legal. Take a look at the discription of the tecnology listed for the CDI in the line of injectors and their placement , turbo, and valving, same as in our CRD. Also of note is MB has conflicting reports as to engine size and hp, 3L to 3.2 for the V6 and 211 to 221 hp, I wold hazard a guess that the engine is actually a 3.2L with hp drop for AdBlue system. You should see all the extra exhaust plumbing hanging on the BlueTec E320 at the website, maybe they bump the HP a little to hual all the extra metal.

MERCEDES-BENZ DEBUTS WORLD'S CLEANEST DIESEL
NEW YORK CITY - Mercedes-Benz is debuting the 2007 E320 BLUETEC at the New York International Auto Show, open to the public April 14 - 23, 2006 at the Jacob Javits Convention Center in Manhattan. Featuring the world's most advanced diesel technology, BLUETEC combines several innovations to minimize exhaust emissions.
BLUETEC - A New Blueprint for the World's Cleanest Diesels
Mercedes-Benz diesels have an innovative, high-tech powertrain that's highly efficient and powerful. They offer four-cylinder fuel economy with V8 torque.
To ensure what exits the engine is already as clean as possible, BLUETEC is built on a foundation of advanced engine design that includes four valves per cylinder, centrally located piezo-electric injectors, third-generation CDI direct injection, a turbocharger with variable nozzle turbine and exhaust gas recirculation. Central to the E320 BLUETEC is a new 3.0-liter V6 turbodiesel engine producing 210 horsepower and 388 lb.-ft. of torque, which replaces the in-line six found in the previous E320 CDI.
The BLUETEC system depends on the use of ultra low-sulfur diesel fuel (less than 15 parts per million) that becomes available throughout the U.S. this fall. Sulfur is a natural element in most mineral oils. It has a corrosive effect on engines and is a major cause of particulate emissions. The availability of extremely low-sulfur fuel enables the use of reliable particulate filters and efficient nitrogen oxide after-treatment.
The E320 BLUETEC incorporates four after-treatment units in the exhaust stream - an oxidizing catalytic converter, a particulate filter, an advanced "denox" storage converter, and a SCR catalytic converter.
A BLUETEC Module for the Future - AdBlue
To meet even more stringent emission requirements the a BLUETEC system could be equipped with another module - AdBlue injection. A water-based urea solution, AdBlue is carried in its own small tank and metered into the exhaust in minute quantities, so small that the tank only needs to be refilled during routine scheduled maintenance. When AdBlue is injected into pre-cleaned exhaust gas, ammonia (NH3) is released, converting nitrogen oxides into harmless nitrogen (and water) in the downstream SCR catalytic converter. Called SCR, for selective catalytic reduction, this process creates the most effective method of exhaust gas after-treatment currently available.
In Europe, AdBlue injection has already proven effective in more than 15,000 Mercedes-Benz commercial vehicles, and the AdBlue supply network covers some 1,500 locations.
Real-World Benefits to BLUETEC
Not only is BLUETEC the cleanest diesel technology in the world, which can meet the most stringent emissions standards, but it also helps customers make tangible fuel savings and reduce dependence on oil imports. With its super-clean exhaust, BLUETEC can also increase the appeal and the sheer availability of diesel vehicles.

MERCEDES-BENZ E320 CDI BREAKS WORLD RECORDS
Around The World In 30 Days - Four Times
Laredo, TX - The new Mercedes-Benz V6 CDI diesel engine has achieved an impressive list of world records this weekend in Laredo, Texas. Three standard-production E320 CDI (Common-Rail Direct Injection) vehicles equipped with the 221-hp powerplants covered distances of 100,000 kilometers, 50,000 and 100,000 miles respectively in world-record times.** Combined the three record diesel vehicles traveled the equivalent of almost eight times around the world, with the 100,000-mile record car achieving an average speed of 139.699 mph. Despite the extreme stresses, the maintenance-free diesel particulate filter held up magnificently over the entire record distance without any deterioration in performance -- further testimony to the reliability and durability of this exhaust technology.
This historic event follows last year's successful return of the Mercedes-Benz diesel engine to the luxury brand's lineup. The E320 CDI exceeded sales expectations by more than 38 percent with 4,158 units sold. Boasting strong acceleration, excellent fuel economy and low noise levels, the latest generation of electronically-injected CDI engines is helping to change U.S. consumers' dated perceptions about diesel powertrains.
The E320 CDI achieves 27/37 mpg for city and highway driving, respectively, translating into up to 30 percent better fuel economy than comparable gasoline engines. A showcase for the latest in diesel engine technology, the 3.2-liter diesel engine can propel the E320 CDI from 0 to 60 mph in just 6.6 seconds and cruise up to 780 miles on a single tank of fuel.
With precise electronic control of fuel delivery, hand-in-hand with an oxidation catalyst, the E320 CDI can pass current 45-state emissions standards. With increased availability of low-sulfur "clean" diesel fuel in the U.S. imminent, Mercedes-Benz engineers are optimistic that the CDI diesel can eventually meet emissions standards in all 50 states.
