Rolling coal is the practice of tampering with a vehicle’s emissions control system, causing it to spew black clouds of sooty exhaust.

    The smoke is a symptom of over-fueling a diesel which does actually make more power, all else being equal.

      To a point. After that you’re just making more smoke, and washing out the cylinders, drastically reducing the engine’s life. I take some consolation in the fact that most of the bros rolling coal will absolutely not be able to afford a replacement engine once they trash theirs.
