an abbreviation for Volumetric Efficiency usually used in internal combustion engines.
usual VE of stock naturally aspired engines is 80% at max. torque and 75% at max. power
stock TDi engines ca. 90% at max. torque and 80% at max. speed
heavily optimized racing engines achieve VE =>100%
VAG claims 2-valve per cylinder TDi with VE up to 95% and 4-valve design up to 98%.
