Has anyone seen actual curves for the horsepower and torque performance? On the Lexus site the "Performance and Technology" video states that the IS250 has 90% of its power between 1800 and 6500 RPM. these seem to be harder to find recently.

Greentingray is not crazy, as I am seeing the same issue with my new IS 250 '08. This was surprising to me that even though I have the AC on Auto and the temperature outside is 68F, I can set the temperature to 78F and COLD air still comes out the center vents. I have an Acura MDX and other cars and none have cold air coming out the center vents when the heat is on. I did read somewhere that if the sensor detects hotter air inside than outside the air will also come on (shows arrows at both head and feet on NAV), and I believe this is likey b/c of radative heat transfer through the glass making the inside actually hotter. But that is some really COLD air coming in. I was searching this forum for this specific reason and I'm glad to see I'm not alone. I guess this is something that is probably not broken, but something that is intended fuctionality that doesn't quite work as expected.
