Challenger is now live on DealerConnect under the order status tab, as "LC family". The SRT8 model is the only one listed for now, and it's code is LCDX22.

I asume that this means that the SRT8 will be the only Challenger offered initially, with a 5.7-liter R/T (LCDP22) and a base V6 model (LCDHCC) in 2009.
