This is some pretty cool tech:

although it seems like it's been around for a few years in the diesel world.

November 16 of this year marked the day a century ago that Dr. Alfred Buchi received the first patent for an exhaust gas turbocharger. Porsche will be celebrating the turbo’s 100-year anniversary a little late when it introduces the next 911 Turbo sometime next year with Variable Turbine Geometry.

Sounds neat, they have a similar turbo for harley's - I forget the name of it but it was on some shadetree mechanic show a few years back.

While some diesel engines have enjoyed this technology since the Nineties, the higher exhaust gas temperatures created by gasoline engines necessitated the creation of new heat-resistant materials to handle the hotness.

hotness....is that a technical term?
