Daimler Trucks North America has announced pricing for meeting the EPA 2010 standards with the Cummins ISX15 engine.
The company will add a surcharge of $9,000 to vehicles equipped with 2010 ISX15 engines, Cummins' big-bore engine.

Daimler offers both Cummins and Detroit Diesel BlueTec as options for meeting EPA's 2010 emissions standards through selective catalytic reduction technology.

Recently, the company announced pricing for vehicles equipped with Detroit Diesel DD15 and DD16 big-bore engines, as well as the medium-bore DD13, which was $9,000 per vehicle. A surcharge of $7,300 will be added to vehicles equipped with the Cummins ISC8.3 engine, and a $6,700 surcharge 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 supporters say can significantly improve fuel economy compared to EPA 2007 engines.

SCR is an emissions technology that treats NOx emissions downstream in the exhaust so that the engine can be tuned to run more efficiently and economically. SCR technology consists of an after-treatment 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.
