2004 Chrysler 300M Special Trim Overview

The only new addition to the 2004 Chrysler 300M Special was the availability of a navigation system.  This was the third and final production year of the Special, as the 300 name would receive a total redesign for 2005.  The Special was introduced in 2002 to offer 300M buyers a more performance-oriented option.  
Some drivers of the 300M had found the suspension tuning too stiff for a luxury car, so that setting was moved to the Special.  This trim is also set apart by a stronger ABS system, carbon fiber interior trim, 18-inch wheels with Michelin Pilot Sport tires, and increased-effort steering.
The same 3.5 liter V-6 was present, but Chrysler had been able to draw a bit more power out of it.  Horsepower was increased from 250 to 255, and torque from 250 to 258 pound-feet.  The transmission pairing was the same: 4-speed automatic with AutoStick.  The Special's acceleration improved slightly over the 300M, to a 0-60 mark of 7.4 seconds.  The powerful brakes took the 3500+ pound sedan back from 60 mph to 0 in 114 feet.
While the Special did offer a more road-responsive ride and improved handling, ride comfort was sacrificed.  The larger tires produced additional road noise that could not be silenced by the cabin's insulation, and the Michelins combined with the stiff suspension to produce a steady rumble on uneven surfaces.
