My 8010 is at the dealer for some work, and yesterday when i stopped to check the progress, i saw an 8120 and a 9120 that appeared to be case test machines due to all the extra wires running into the cabs on both. The 9120 looked fairly normal, but when i took a closer look at the 8120 i noticed that the muffler looked completely different than production units. When i climbed up on the engine deck, i noticed that the machine had a tank for adblue fluid. Is this on all the new machines, or is this something case is testing to meet the upcoming emissions? Has anyone else seen this?
