Mazda's new skyactiv lineup includes a diesel, and

" Diesel engines are wonderfully efficient, but they require costly urea-injection systems to match gas-engine exhaust emissions.
mazda's new 2.2 liter diesel, however, meets all U.S. regulations, without urea injection.
Plus, when it arrives in 2013 in the cx-5 it will produce around 310 lb-ft of torque and rev to an UN DIESEL LIKE 5000 RPM."


um... isn't the MB engine rev limited to 5100 RPM? in like, what 76?

5400rpm........honda has been making diesel accords and civics for years and subaru has also had a nice diesel boxer AND Michigan has had a ford diesel focus.

All are trash compared to the 616 and 617.........just sayin ;D

I find it amazing that American Car Manufacturers seem to think Turbo technology is "Latest Thing!"

It would be more appropriate to make that comment about American car BUYERS.
The manufacturers KNOW all about technology, but their advertising agencies will say anything to sell more cars.

When the Chevy Colorado came out a few years ago, many of the young kids who were buying them were all agog about how far advanced was Chevy for bringing a 5 cyl engine to the market. Many were shocked to learn that Mercedes had done it before most of them were born.

Urea injection? Never new such a thing existed. My 04 TDI doesn't have urea injection. Maybe standards have changed since then?

I think urea became standard in 08 or 09... maybe later even...

It is one of the means to control NOX emissions, which have been ramping down from 2005-2010. Most every manufacturer is using urea (Diesel exhaust fluid) instead of more EGR and the adsorber catalyst. International and the Dodge PU do not use it, but the 4500-5500 C&C series do. Personally, I think it's the way to go, as it allows the engine to be tuned more the way it's supposed to be. For example, the new VW Passat TDI uses DEF, where the Golf and Jetta do not. The heavier Passat gets better mileage than its smaller counterparts with the same engine. The fluid is a 32% concentration of urea (made from natural gas) and deionized water. It is the safe way to get ammonia into the SCR system, where it reacts with the NOX in the exhaust to produce nitrogen and water vapor.
