Both of you suck at car analogies.
Let's say Nissan makes an engine. V6, 3.8L. They advertize it as being 250HP, promote it mainly by putting it in racecars and winning races, and a whole lot of other technical specs get handed out to reviewers to gush over, but nobody really reads them except nerds.
They then make a variant engine. Same V6, but they cut the stroke down so it's only 3.0L. They advertize it as being 200HP, promote it with some more racecars that don't win the overall race but are best in their class, and again they hand out a small book worth of technical specs, this one with a minor error in the air flow rates on page 394. Somebody forgot to edit the numbers from the 3.8L engine, so even though the actual airflow is more than enough for the smaller engine, the numbers originally given look bigger. Nobody from marketing was told about the airflow change, because it was a weird side-effect of something they got rid of related to turbocharger compatibility, and nobody thought to ask the engineers to double-check all of their numbers since only like 200 people would see it worldwide anyways.
Once actual customers get their hands on the new engine, most of them are pretty happy. The 3.8L is better, but it costs like twice as much as the 3.0L, so whatever. One customer is driving on this godawful, decrepit highway that hasn't been repaved since the Eisenhower administration built it, and obviously has some issues. Rather than blame the shitty conditions, he takes a look at the engine, and finds that if you take an air compressor and blow air through the intakes, not as much gets to the engine as in the 3.8L. He then bitches about it online, and other people find the same thing. Motorheads being just as collectively retarded as any group, they build a standardized test set that completely ignores realistic driving conditions and pretty much only identifies this particular oddity in this particular engine, and take to the streets waving torches and pitchforks when they find the air flow value on page 394 isn't the airflow they're getting.
Someone at Nissan hears the noise outside, checks with their internal books and finds the typo. They start explaining as quickly and loudly as they can, but the mob's angry and nobody's going to stop it with logic at this point.
Meanwhile, the smart motorheads are sitting back, waiting for Nissan to drop the price on the "tainted" engine so they can pick one up for cheap themselves, since it's actually a perfectly fine engine, already a pretty good one for the price, and way more fuel-efficient than Audi's equivalent.
