| The SD80MAC is a 5,000 horsepower (3.7 MW) C-C diesel-electric locomotive. The SD80MAC uses a 20 cylinder version of EMD's 710G prime mover, and is the first diesel locomotive to use a 20-cylinder engine since the SD45/SD45-2. The SD80MAC introduced a wide radiator housing similar to GE locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models. Key spotting difference between the SD80MAC and SD90MAC include: no external rear sandbox on the 90MAC, rear number boards, and the placement of the front numberboards (above the cab windows on the SD80MAC, on the nose on most SD90MACs).|
