Quieter, smoother power

Multiple injection events per cycle deliver smoother, quieter operation even at lower engine rpm ranges, exactly where the Mack® MD does most of its work.

Compact & fully capable

The B6.7's fully integrated aftertreatment system combines SCR, a dosing unit, and DPF into one flow-through unit, simplifying installation and preserving valuable space on the Mack MD chassis.

Protection that pays for itself

Fleetguard® filters with NanoNet® technology provide 10 times better protection against contaminants than conventional fuel filters, reducing wear and lowering long-term costs of operation.

Two Rating Families

The right power for every application.

The B6.7 comes in two distinct rating families to fit your operation. Efficiency ratings from 200 to 260 hp are optimized for inner-city and lower-speed duty cycles. Performance ratings from 280 to 315 hp feature a unique turbocharger and piston design for operations that demand more power and torque.
