The Chrysler 300C SRT-8 was introduced at the 2004 Pebble Beach
Concours d'Elegance. The 300C SRT-8 is powered by a 6.1 L Hemi
V8 which produces 425 hp (317 kW).
Additional features of the SRT-8 version include leather SRT-8
performance-embossed seats and 20-inch forged, polished aluminum
wheels, Brembo brakes, and rear lip spoiler.
The earlier 300C SRT-8 models, 2005-2006, didn't have the lower
air dam which was introduced in 2007. This improves cooling
to the engine by as much as 30%.
