Not really news, Nissan and Toyota started doing this years ago. The
Skyline GT-R and Supra TT along with the Mitsubishi 3000GT VR-4 (aka
Dodge Stealth Turbo) all had this in the early 90's, with the Toyota
and Dodge both being widely available. The big deal is Ford doing it
on mainstream American cars with turbo 4's replacing V6's where it had
previously been used as a replacement for V8's on high-end sports
coupes previously.

This is now getting popular, but it's been around since the 80's.
