i dont think that there would be an AWD challenger simply because there is no proven market for it...

i grew up in a very hilly area, with a rwd truck for a winter driver, and i had no problem...too many people anymore trade in driving ability for 4wd, but it doesnt work, which is what accounts for the high number of accidents involving 4wd vehicles. i have no problem getting around the detroit area in the winter with either of my rwd vehicles...
