"I suspect the test mode is not used for calculating the MPG."

AND you would be wrong...

MPG is calculated using the total hydrocarbon emissions to determine the amount of hydrocarbons (i.e., fuel) burned per mile. Gas and diesel vehicle MPG is determined this way and has been since MPG standards were established.

Huh? No way. They drive a test course and see how much fuel you used.

That NoX emission is tied to combustion temperature, which is related to fuel injection timing. Advance of injection timing relative to TDC increases peak temperature and pressures, which increases NoX quantities produced. A multi-step injection profile limits peak temperature and is a common NoX control avenue.

See post #78. If VW were running the tests, well we already know they are cheaters.

Talk about destroying a brand. What a fiasco.

My first (real) car was a used Scirroco:

It ran well, even though my friends said it was a 'beater' I loved it.

Sad.
