The ’07 Detroit Diesel MBE 4000

Detroit Diesel’s MBE 900 and MBE 4000 diesel engines — as with most OE’s — employ EGR technology and a diesel particulate filter in 2007. Like DDC’s Series 60, they’ll also use the DDEC VI electronic control unit. The two engines will also feature a maintenance-free, filterless electrostatic breather to address crankcase emissions requirements. The device will take oil out of crankcase vapors and return the oil back into the crankcase.

The 2007 MBE 900 medium-duty diesel, enlarged to 7.2-liters, will be available in a standard power version with ratings of 190 to 250 hp and 520 and 660 lb ft torque, plus a high performance version with 260 to 300 hp and 800 to 860 lb ft torque.

The MBE 4000 engine also has new torque ratings — 1250 to 1650 lb ft — along its power range, which runs from 350 to 450 hp. A new rating is 370 hp with 1250 lb ft torque. Another, useful in weight-sensitive applications, offers 450 hp with 1650 lb ft of torque.

Parent company DaimlerChrysler’s pricing prediction for its 2007 heavy-duty engine lineup suggests a rise “in the neighborhood of $7000-$10,000 for DDC’s Series 60 and MBE 4000 engines and between $4500-$6000 for medium-duty
Cummins and Mercedes offerings.”

DaimlerChrysler has also announced that it’s preparing to create a common global engine platform across all its markets. It will be introduced in the U.S. and Canada next year and other markets in 2008. Full production ramp-up will take place in late ’08 and ’09. It will coincide with a brand new chassis and truck design lineup, which the company will announce in more detail a year from now.
