From what I understand, the increased static compression ratios made possible by direct injection and the increased dynamic compression ratios made possible by forced induction both contribute to elevated NOx levels because of the higher combustion temps and pressures.

"No. My Finnish is fine; I am from Finland. Do you have any water?"
Anecdotally, service advisers at my former company indicated that DI was causing build up of carbon in the exhaust of M-B products. The same is true for other cars equipped with direct injection. This, and turbocharging as Ferrer alludes to (sadly I don't habla Espanol or Catala) are not the be all end all to high mileage and low emissions that regulators and manufacturers want.

DI can make carbon build up worse, that combined with the fact that engines are rather more powerful than they used to be means that most people never really give their car a good ol' Italian tune up in their regular driving means that the carbon is never blown through.
Or something. It's an excuse to floor your car anyway.

Welp.

I'm not really all that sympathetic towards VW. They cheated their customers all around the world, and now they're hit with a big fine. Big whoop. That being said, I never really liked VW cars to begin with, so I'm pretty biased.
I am sympathetic for Red Bull though, because they got affected by something beyond their control.
The only thing I'm concerned with is Porsche, which is the only car company in the VAG group that I really care for.
In the long run of things, how will this affect other marques such as Bugatti and Audi?
It'll affect Audi by being the same engine used in it's 2011(?) green car of the year A3.. whoops.

Apparently there's also a problem in Europe, affecting hundreds of thousands of Seats and Skodas too.
Goodbye diesel?

I hope to see more realistic fuel and emissions ratings come from this. The EU and EPA's listed fuel economy and emissions ratings seem to be sheer fantasy. Joe public knows now.

At least EPA's are somewhat achievable. And if you can't, you file a lawsuit against the manufacturer and wait for the millions to come rolling.
European ratings are just a joke, and all the cheats are legal.

By the way, on (somewhat) related news:

I like where Toyota is going with this...
NEWS: Toyota S-FR Concept is the Sports 800 reborn | Japanese Nostalgic Car
Of course, whether it will be produced or not is still a question.
But with a rumored inline-6 sports car with BMW, things are looking good for Toyota, at least in terms of concept cars.
Hope they don't pull a Nissan and kill it like they did with the ID-X.
I like it as a concept, but it looks a little bit cartoonish.
Also, the interior is very production-like to just be a concept.
Lack of charisma can be fatal.
Visca Catalunya!
