Let me add for the satellite radio, it's also available from Priusxm.com
I had a Sirius starbase installed below the display screen in the little
compartment. So I have an integrated XM and an FM Modulated Sirius unit. (I
spend a lot of time in the car). As for the A/C, bumper-to-bumper traffic,
does cause the hybrid battery to run down in about 20 minutes. At that time,
the gas engine kicks on.
The optimal temperature for gas mileage is 60-70. When it hits the 80-100
range, the A/C runs more frequently. I average about 45mpg during my daily
commute. My record was 49mpg going 74mph back from FL. Although these
figures are not near the EPA's, they are far better than anything else out
there with realistic driving conditions. BTW, I have a "lead foot" and
higher speeds (over 55) do adversly affect gas mileage.
