Mercedes Benz previews new diesel for U.S. with E250 BlueTEC concept

Follow Viknesh

Mercedes Benz has just revealed its new E250 BlueTEC, a concept vehicle based on the 2010 E-Class and featuring the company’s new clean diesel technology. According to Mercedes Benz, the exhaust treatment system used in its cars means that the vehicles will comply with even the most strict emissions regulations that are expected to be implemented in the future, both in the U.S. and Europe.

The E250 BlueTEC concept, which made its debut today at the New York Auto Show, previews a production E-Class diesel with the technology. Currently, the concept uses a combination of a 2.2L four-cylinder diesel engine, as well as a two-stage turbocharging system and direct-injection technology.

To manage all this, an electronic engine control system reacts precisely across the full range of operating conditions to optimize the combustion process. This includes an exhaust gas treatment system that incorporates an oxidation catalytic converter mounted close to the engine, as well as a diesel particulate filter at the rear.

At the heart of the BlueTEC system are two SCR catalytic converters (Selective Catalytic Reduction) with an “AdBlue” injector positioned upstream. AdBlue is a synthetic, aqueous urea solution that enables the nitrogen oxide emissions to be converted into harmless nitrogen gas in the SCR catalytic converters, thereby reducing emissions greatly.

In fact, the BlueTEC system works so well that its technology will allow Mercedes Benz vehicles to meet global emissions regulations that are not being implemented until 2014. Autumn of 2009 should see the release of the E350 BlueTEC in Europe, and with its V6 diesel engine featuring over 211hp (155kW) and 369lb-ft (540Nm) of torque it should prove to be popular. No U.S. release has been announced but given the unveiling of the latest E250 BlueTEC concept on American soil it will only be a matter of time.

  1. I know some people will complain it does not have enough hp, but torque is what matters with diesels and this would be excellent with a second diesel offering for America in the E-class

    Bad stuff?

  2. Can I park my new E250 with the gear at the neutral position instead of a park position ?

  3. I looovveee diesels, and BlueTec has had me very optimistic. I think it is brilliant, if only the manufacturers were brave enough to make a full-court press on the argument for passenger diesels here. Hopefully MB will get the ball rolling; they've stood by diesel, and many of their old Turbodiesels are still on the road, and likely will be long after all of us are dead and cockroaches have inherited the earth.
    with BlueTec, the massive torque, and the good economy, what's not to love America?
