With the advent of the most recent Porsche 911 Carrera and Carrera S,
virtually every 911, from the bottom up, is now turbocharged.
(Exceptions? The purist GT3 models, and the outgoing GTS.)
Now Porsche is launching the top-of-the line 911. Guess what it's
called? Turbo. If you think that's confusing, we won't contradict you.
So, just like almost all other 911s, the Turbo is turbocharged. In the
case of the new range-topper, however, it is a 3.8-liter flat six that's
being force-fed by two variable-geometry turbochargers. These 'VGTs'
for gasoline engines were available from Dodge and Peugeot in the early
1990s, but today only Porsche continues to develop and use the
technology.
