Explains the constant air quality alerts over there
I sat and watched an interview with a retired German car engineer. He went over the various ways that diesels have advantages, and the four ways that things can fit or never fit.
So you have performance, fuel economy, durability, and emissions. You can generally group these to fit only in certain ways. You can always have great performance, great fuel economy, and great durability....as long as you lessen your desire on emissions.
The minute you raise emissions as your number one priority....at least one of these other three must fall dramatically.
Then he pointed out...most every single German who buys a diesel...has a 100 km or more drive each day...maybe even 300 km. He pointed out that even a decade ago....they had the capacity to build a filter device to take out the particle problem but this meant lesser mileage and lesser performance. No one in VW could sell the leadership on making a vehicle that got lesser mileage, and poor performance.
So here we are today....back to the same problem. I read a month ago that some parts company in Germany has a development where the temperature of the engine would be modified, keeping the same performance, and achieving the air quality desired for today, and that expected upgrade for the next decade. The problem is that virtually everyone is so negative about diesel engines now....that you can’t sell this idea. The company probably put in a minimum of 500-million to develop this, and it’s just too late to make folks happy.
“Explains the constant air quality alerts over there”
Air quality alerts exist now only because of stupid and anti-scientific regulations constantly lowering alert thresholds. It’s all a scare-based scam feeding a whole lot of fear merchants and parasites.
