In the press “ The engine responds very nicely to low-rpm operation in the bottom five gears, when I usually shift between 800 and 1, 000 rpm. Startability is great with that gear combination. In the higher gears, shifts were comfortably made at 1, 200 -1, 400 rpm. Image source: www. truckinginfo. com/279676/test-drive-cummins-x 12 -dieselengine-version-2 -0 The engine brake was fantastic for such a small-displacement engine, and when the revs get up to 2, 100 or so, you can really feel it digging in. On a less technical level, I found the engine to be very quiet, and it has a very pleasant low growling sound. It won’t bother anybody. The variety of ratings is astounding; they go up in roughly 25 rpm increments from 325 to 500. ” �Jim Park via “Test Drive: Cummins X 12 Diesel Engine Version 2. 0” Public 3

Awarded HDT Top 20 Products Cummins Inc. has been awarded Heavy. Duty Trucking’s 2018 Top 20 award for its X 12 engine platform. This award signifies the innovation that delivers the lightest heavy-duty engine in North America. The Cummins X 12 redefines the entire medium-bore engine category (10 liter – 13 liter), setting new standards for productivity in regional-haul, vocational and intermodal truck applications. Public 4

What have customers said? “The engine has been operating for 70, 000 + miles and no engine issues. We’re still averaging above 9 mpg with the truck now using winter blend fuel. ” “Fuel Economy of X 12, 8. 39 mpg, puts it at the top of the fleet for 3 month in a row. ” Regional Haul 77 k Jacksonville, FL “We can haul an extra ¼ ton in this truck. It’s about 500 -600 pounds lighter. ” Dump Truck 70 k Southeast US Regional Haul Birmingham, AL Internal Use Only 5
