The SVX came with the auto AC system. It worked great as far as keeping you warm or cold, but it's choices as to which vents it used was confounding...and there wasn't a manual mode to make it come out the locations you wanted....just a dial that provided options which the system constantly over-rode. I didn't like it all that well other than the ability to set the temperature at which the system engaged (digital readout). Hopefully the STi will use the temperature setting like the SVX, but allow us to direct the vents it comes out at....oh..and set the fan speed too.
It was 92 here on Friday. It was raining in the morning when I parked at work. By lunch time it was HOT. The car thermometer said 99 when I left the lot. I live only 3 miles from work and by the time I got about halfway there It was cool and comfortable.
It was 108 degrees when I left work this afternoon and the STi's AC was easily able to cope. I live in Arizona, so low humidity. I had the temperature set to 75 and the fan on the second highest manual speed. As a plus, the fan is quiet too. Only gets a bit loud on the highest speed setting, but I've heard worse.
