The only way I see Dodge having ANY chance to compete is to seriously take some weight out their current Challenger chassis platform or shove a 600+hp powertrain in it. Neither seems possible without pricing itself out the pony car market!
I've met Ralph Gilles a few times at a few Mopar events and he and his crew at SRT want a pony car that'll be on par or better than the ZL1 and Z28. Maybe pony car history will repeat itself like back in the late 60's and early 70's when Dodge came late to pony car market with the Challenger. I hope by 2015 or 16 the Dodge boys will have something wicked for us to play with!
