The torque of turbodiesel power is worse than heroin... addicting, really really gotta keep coming back for it, once you've had it.
There are two ways to get diesel torque.
The old fashioned way is low rpms, large cylinders that give lots of time for fuel to combust and generate high cylinder pressures with lots of time to push down on the stroke.
The new way... high rpm... small displacement.. is to extend the fuel injection to well past top dead center, allowing lots of fuel to burn but very little time to extract the energy before bottom dead center is reached, and the energy is out the door.
In other words, them full throttle torque is purchased at a massive cost in fuel economy.
But diesel buyers don't seem to know or care about that.
I will take the old fashioned 2,000 rpm red line!
When your MFA is telling your every move of the throttle on the dash, along with a Scan Gauge II telling your Gallons per Hour flow... you learn real quick where the efficient part of the power band lies. I try to shift at 2000 rpms, I've had no problems driving 65 mph at 1850 rpms in 6th gear and pulling 52 to 54 MPG by pencil and paper at the gas station after the fillup. Quite satisfying when you see how midsized a 2012 passat is, yet how efficient, when driven properly. :B
