Turbo Performance Engineer (TPE) display
The TPE display can be activated by pressing the touch-sensitive
ring for 3 seconds. Each time it is pressed, it cyclically passes
through its 5 functions: time displayed in 12-hour format, external
temperature displayed in degrees Celsius or Fahrenheit, pressure
reading of turbo in bar or psi, and two screens that display the
main characteristics of the turbo engine.
- Turbo: indicates the working pressure of the turbocharger in bar
or psi.
- Turbo Efficiency (TE): indicates the percentage of maximum
turbo efficiency (seen as the maximum torque obtainable by the
car for a given fuel consumption level or specific amount of fuel
used) available to the driver depending on the number of revs.
