See AutoWeek from June 21, 2004:"Either way, the SRT-6's power puts it under the 1:10 power-to-weight ratio, or approaching sports-car territory. Curb weight on the coupe is 3240 pounds. If we go with the 330-hp figure, that makes the power-to-weight 1:9.82; and with the 349-hp figure, 1:9.28. Both are well ahead of the 1:14.2 for the normally aspirated Crossfire coupe.
"Whatever the power, it is all routed through an upgraded version of the Crossfire/SLK's five-speed automatic with Auto-Stick. As with many small-volume gran touring coupes, and with SRT-6 sales expected to come in somewhere in the low thousands, it would not have been worth it to federalize another transmission, especially since manuals sell in far lower numbers than automatics in the United States."
Hope this helps.
