It was very similar to the LBZ, but it featured an all-new emissions device, a diesel particulate filter. While it reduced emissions output drastically, the DPF system on the LMM resulted in these trucks having terrible fuel economy.

While the power output was increased to 365hp and 660lb-ft of torque, its fuel economy suffered materially due to the new DPF system. Paired with the trustworthy Allison 1000 transmission, the LMM actually outperformed both Ford’s 6.4L Powerstroke, and Dodge’s 6.7L Cummins of the time.
