Nicked from some website.
MYTH #1
Diesel engines are smoky and dirty.
FACT
Diesel smoke is comprised of soot from unburned or partially burned fuel. Modern computerized fuel control and management coupled with ultra-high-pressure common rail fuel injection have virtually eliminated diesel smoke. What little smoke remains is nearly invisible, and even that trace smoke will be gone when the petroleum industry switches over to ultra low sulphur fuel, as mandated by the EPA by 2006. As for dirty, no smoke means no soot, and no soot means no dirt.
MYTH #2
Diesel exhaust smells bad.
FACT
The smell associated with diesel engines in the past came from incomplete combustion, smoke, and high sulphur content in diesel fuel. As mentioned above, electronic fuel management has dramatically improved combustion and nearly eliminated smoke. Today’s diesels won’t offend most folks, and when the sulphur goes, even those people with sensitive noses will be hard pressed to honestly object.
MYTH #3
Diesels have to be noisy, especially at idle.
FACT
There used to be a lot of truth to this statement, but new diesels with a feature called “pilot injection” have virtually eliminated the clattering sound associated with diesel engines. Many of these diesels are so quiet that it takes an educated ear to recognize that the engine is a diesel when it goes by or is stopped at a stoplight. Unfortunately, there are enough noisy older diesels on the road to sustain this myth for some time.
MYTH #4
Diesels are slow and sluggish.
FACT
All new automotive, light truck and motorhome diesel engines sold in America today are turbocharged. These turbo-diesels are responsive and powerful. They are capable of accelerating quickly, and they have high-torque output for climbing grades or sustained high-speed operation. Today’s turbo-diesels also are responsive to performance upgrades that make their performance nothing short of incredible. (see ”Project Sidewinder Goes to the Salt”)

still pish and don;t rev much and have very small powerbands and also a lot of noise is reduced due to sound proofing.
another fact VAG are resposable for the logarithmic technology increase in turbos both for diesels and petrols
