The ‘6’ in this photo is in the top of the instrument panel of the Subaru Legacy GT sedan I drove recently.
(Okay, it's not a great photo; Lady Leadfoot was driving, and I took the shot from the back seat…).
The '6' represents the gear the manual-transmission car was in.
I don’t think I have ever seen a digital gear ratio read-out in a pure manual car before.
Automatics, or Dual Clutch auto-shift manuals, yes.
In this case, the number only shows up when the engine is running, and the clutch engaged.
(That's why I had to take the photo while she was driving the car.)
On the surface, this makes about as much sense as a tachometer in an automatic car.
Not sure what the point of it is.
But maybe if you forget what gear you're in...
One interesting thing - when you switch on the car and the IP goes through its diagnostic test procedure, the number that shows up is '8'.
Hmm-mm - does Subaru have an eight-speed manual transmission in the works?
