Hi All,

All I can say, is a variable cooling intake is very much needed. We have had 20 to 30 mph steady winds out of the direction my home trip as the crow-flies is in. With Hypermiling technique driving my Prius, the car does not get into a warmed up state sufficient to ensure an engine shut down below 35 mpg, until like 3/4's the way into the trip. But Friday, its like the hottest day of the year here (95 F with 105 F THI), BUT with 30 mph gusting to 40. The car never got fully warmed up over that 1 hour / 23 mile trip! The wind was making the air speeds up to 80 mpg, and with pulse and glide, the car just did not reach the temps where it would shut down the engine.
