Daimler Trucks North America (DTNA) will offer customers their choice in EPA 2010-compliant engines and emissions technologies from both Detroit Diesel and Cummins. A $9,000 surcharge will be added to vehicles with Cummins ISX15 engine and emissions technology.
As previously announced August 8, 2009, vehicles equipped with Detroit Diesel BlueTec emissions technology and DD15 and DD16 big-bore engines, as well as the mid-bore DD13, will be offered at the same $9,000 surcharge per vehicle. A surcharge of $7,300 will be added for the Cummins ISC8.3 engine, and $6,700 will be added to the price of vehicles equipped with Cummins ISB6.7 engines.
The surcharges reflect costs associated with adding selective catalytic reduction (SCR), which has been proven to improve fuel economy compared with EPA 2007 engines while reducing long-term operating costs and meeting emission standards set by the US Environmental Protection Agency (EPA) that take effect January 1, 2010.
SCR is an emissions technology that treats nitrogen oxide (NOx) emissions downstream in the exhaust so the engine can be tuned to run more efficiently and economically. SCR technology consists of an aftertreatment catalyst system that allows engine exhaust to be treated with a non-hazardous fluid known as diesel exhaust fluid (DEF) that reduces harmful NOx into simple nitrogen and water.
