Nearly identical to the LBZ, the LMM debuted midway into the 2007 model year (2007.5). The slight variations between the LBZ and LMM gave the LMM a small boost in power output. The LMM features new emissions equipment that meet strict new diesel emission laws, and is currently in production today. Using a diesel particulate filter (DPF) and active regeneration technology, the LMM cut particulate matter emissions by 90 percent over the previous generation.
