What does FSI stand for, as in 3.2 FSI?

Default 'future of spark-ignition'

fuel is injected directly into the combustion chamber rather then the intake port, reducing fuel consumption by 15 percent.

Default maybe: Fuel Stratified Injection ?!?!? - however ...

AUDI AG glossary says:

FSIŽ direct injection technology increases the torque and power of spark-ignition engines, makes them as much as 15 percent more economical and reduces exhaust emissions. In contrast to conventional intake manifold injection on conventional spark-ignition engines, FSIŽ engines inject fuel directly into the combustion chambers. This technology dispenses with the throttle plate. That `unthrottles' the engine, reduces heat loss and thus increases output while reducing fuel consumption.
The system uses two charge-air supply modes: stratified charge at partial load and homogeneous operation at full load. In the stratified charge mode, an combustible fuel-air mixture is only produced in a defined zone around the spark plug. The engine management electronics monitor engine load and adjust injection timing, pressure, quantity parameters as well as the air flow inside the cylinder via the air intake channel. At full load, FSIŽ increases compression as well as engine efficiency and performance.

Default It also requires very high fuel purity or the extremely high pressures

used by the system, will eventually break down the delivery system (pumps/injectors). Mixed news on whether North American fuel at present can meet those standards.

Default Word is that the cars testing here, have had regular

non-FSI engines in them (V6 and V8), and that we may see a delay before getting FSI.
