It would also seem that for some reason turbo engines aren't suited to GDI.
Or at least from the statistics of current manufacturer releases.  It would
seem that all the economy cars are going to GDI, and many of the upmarket
models (ie lexus etc).  However any sport performance cars seem to not
include GDI in the range...

I'd have thought that it'd be something that you'd want to put on everything
that you possibly could.  Although maybe the higher intake pressures with
turbo engines makes it inpractical.
