| On the eve of the North American International Auto Show, Mercedes-Benz takes
the wraps off the Vision GLK, a compact SUV powered by its fourth-generation common
rail diesel mill, which will be ready to compete in all 50 states.
The German automaker says the four-cylinder 2.2L engine powers the Vision GLK
concept. The fourth-generation common-rail direct injection with an injection
pressure of 2000 bar, as well as a two-stage turbocharger system, is rated at
170hp. Torque ratings have not been released, but Mercedes says it will be a segment
leader.
Mercedes notes it has optimized the Bluetec emmission system, developed with
partners BMW and Volkswagen, and mated it to a four-cylinder engine for the first
time. The catalytic converter and particulate filter are assisted by a SCR catalytic
converter. The urea-based solution, AdBlue, is injected into the exhaust stream
and can convert up to 80 percent of the nitrogen oxides into harmless nitrogen
and water.
Daimler AG Chairman Dieter Zetsche says the GL Class signals a concerted effort
by Mercedes to capitalize on the burgeoning diesel market in the US.
"The success is really demand driven and it says something about the untapped
potential for this market," Zetsche says.
If the GLK goes to market, as is expected for the 2009 model year, it will enter
as a 50-state model under the Bin 5 standards and is likely to clear the EU6 emission
standards limits planned for 2015.
Mercedes presents the Vision GLK in two trims, the Freeside and the Townside.
The Freeside has more off-road capabilities and detachable body parts, while the
Townside boasts a sportier feel.
