Which tracks on Formula D / Formule Dé has the greatest straight line?
I don't actually own Formula D so I am relying on the experts over at BGG. The information before relates to the current incarnation Formula D only, Formula De tracks from earlier releases of the game are not considered.

For the purpose of this question two points on the linked thread stand out...


  Baltimore/Buddh
  I particularly like Buddh. The very long straight is the longest on any of the F1 tracks in the Formula D series (F De has several longer ones) and leads into a 1 stopper followed by an in between length to the 2 stopper.


And specifically mentioning 6th gear...


  Sebring/Chicago
  - Sebring: A fun, challenging track, but in my experience, you can get runaway leaders on it if they hit the 1-stop corners just right. You can hit 6th gear easily.
