|The Vision GL 420 BLUETEC.
DaimlerChrysler will introduce a new BLUETEC concept vehicle that meets EPA Tier 2 Bin 5 emissions standards at the North American International Auto Show in Detroit next week: the Vision GL 420 BLUETEC.
The diesel SUV packs a V-8 engine which develops 216 kW (290 hp) and 700 Nm (515 lb ft) of torque with anticipated fuel efficiency of 9.8 litres per 100 kilometers (24 mpg US) and a range of up to 1,000 kilometers (600 miles) on a single tank. Tier 2 Bin 5 compliance would allow this to be sold in all 50-states.
DaimlerChrysler is using the concept to highlight its position that BLUETEC vehicles—especially in the SUV segment—are suited to the American market, where heavy customer demand for vehicles with torquey, large-displacement engines is coupled with the need to comply with stringent exhaust-emission regulations. Higher fuel prices also make diesel’s fuel economy advantage relative to gasoline more attractive.
The latest J.D. Power study “Global Outlook For Diesel” forecasts that diesels will account for more than 15% of new registrations in North America by 2015. On this basis, Mercedes-Benz plans to expand its BLUETEC range.
The company has announced that it will offer three new Tier 2 Bin 5 compliant BLUETEC models (the R, ML and GL Class) in all 50 US states by as early as 2008. (Earlier post.)
BLUETEC is a modular emissions control system that reduces nitrogen oxides in particular. In the E Class, an oxidation-type catalytic converter and particulate filter are combined with an improved, extremely durable NOx storage catalytic converter and an additional SCR catalytic converter. For the larger vehicles—including the Vision GL 420 BLUETEC—a different BLUETEC configuration uses AdBlue injection for urea-based Selective Catalytic Reduction (SCR).
In November, DaimlerChrysler, Volkswagen and Audi officially announced that they intend to establish the BLUETEC brand name as the designation for particularly clean, highly fuel-efficient passenger cars and SUVs with diesel engines. (Earlier post.)
