MB 320 CDI "Bluetec" Hi!
I found this forum while looking for a good list for ULS stations. But was surprised not to see discussion of CDI engines since they are being licensed by MB to everyone and ought to show up in every kind of car or light truck over next few years. Already very popular in Europe.
I have 2007 E320, MB mid-size sedan. Engine is 3 liter turbo CDI diesel. MB calls it "Bluetec" because U.S. drivers associate diesel with bad. This engine makes 208 HP, but also a very real 388 ft-lbs of torque at maybe 1200 rpm. Enormous low-end power, kicks in fast, and available at cruise speeds when wanted. Faster than 3.5 liter standard gas engine E350. Mine only has 2000 miles now but gets approx. 36 mpg highway w/ 2 adults. In ordinary city traffic (in D.C., non-rush-hour) does about 30 mpg, about 24 in stop-and-go.
I have heard that new VW diesel uses same technology (that means Audi too) and others are licensing it also. CDI is single-rail, high pressure injection. I had MB 300D long ago: nice car, but slow, noisy, smelly, hard to start. This engine is quiet, no odor at all, starts better than gas (no pre-heat, no glowplugs) -- and takes off like a sprinter. In 3 months, no problems, mileage keeps getting better, car is very nice. Pricey, but should last a long time.
So . . .it would be nice to find comprehensive, accurate list of ULS (ultra-low-sulfur) diesel stations since this and all other new diesel cars in US MUST use ULS: highway low-sulfur will run but will destroy fancy emissions system. MB list is not accurate. Some brands have station lists, some don't. Does anyone know of accurate combined list? As more new diesels are on road this issue will go away but for now it would be useful.
