I assume this is the "engine" temp, but does anyone know where the actual sensor for this resides, and what is specifically being measured?
water temp?
intake air temp?
engine bay temp?
exhaust temp? (most likely not)

I'd be willing to bet it is like 99.9% of the road cars out there and the temperature displayed is the coolant temp as it exits the cylinder head (i.e., before it goes to the radiator). However, it is not uncommon on modern cars for that temperature measurement to go to the the engine ECU, which, in turn, "drives" the display you see on the dash. The ECU needs that data to manage fuel/spark for optimum performance.

I will change that to 100% which can even be confirmed by owners manual. scale is 140 to 250 deg F coolant fan comes on at 208 deg and full speed at 217; temp icon flashes at 230. and "Engine too hot" is displayed above the car outline. Boiling temp of coolant is 250 F.
