Nope, definitely systemic within the company. The engine is a system that must meet certain requirements. The standard way of meeting those requirements is to have a urea injection system. That&#x27;s what the competitors in the US do; it&#x27;s also what Subaru, for example, don&#x27;t do, and they don&#x27;t sell into the US market.<p>In order to pull off this little 2-person hack that Horn alleges, those couple of software engineers would have to have a major say over the entire engine design. I call bullshit. This little hack ONLY makes sense in the absence of other major engine components.<p>The company culture is clearly absolutely rotten and their execs are liars. Employee morale, especially in engineering, must be through the floor.
