The VW TDI is ratted for up to 7,000 RPM, but the tachometer only goes
up to around 5,000 RMPs. To get the most efficiency out of the engine,
the transmission should be wound up to between 2,500 RPMs to 3,000 RPMs
before shifting. It can take a while just to get the engine broken in.
When new, the TDI diesel engine will yield 475 pounds per square inch of
compression. Over time, the rings of the engine will seal taking the
compression up to 550 pounds per square inches. This will occur over a
60,000 mile break in period; although, basic break in of things like
tires, transmission, etc will occur much earlier, like within the first
1,000 miles. This mean that the power and mile per gallon just keep
getting better over a long period of time.

Horsepower sells cars, but torque wins races.
Horsepower will get you there, but torque will keep you there.
