Brian always drove some sort of Japanese import car in each sequel. What import cars have we seen leaked thus far? This is what I could find:
This is likely Han's:
Brian has appeared in a GT-R in almost all the films:
And, of course, our mystery car:
On that transport trailer video a few posts up we see Dom's car. The white Mustang looks to be Tyrese's:
Which leads me to believe the Japanese import (the BRZ) on that truck is Paul's main car in the European scenes. A BRZ is right at home on tight/windy European roads plus the crew had 5 at their disposal.
The BRZ will appear in the full 60 second spot at the Super Bowl, just watch!
