V6 models have a four-speed automatic transmission while the V8 comes with a five-speed automatic. An all-wheel drive system is available on Touring, Limited, and 300C models.
The 300C can accelerate from zero to 60 mph in just 6.3 seconds, yet it achieves an EPA highway fuel economy estimate of 23 mpg, thanks to the Multi-Displacement System (MDS), which turns off four of the cylinders when cruising or coasting, so as to improve fuel economy by as much as 20 percent.
The base LX model comes with a rather short equipment list relative to most other mid-size and large sedans. Anti-lock brakes and electronic stability control are optional, but standard on the other models.
The 300 offers an extensive list of available entertainment technology. Sirius satellite TV is offered on the 300 for the first time, Sirius satellite radio is also available, and the available DVD navigation system now has a larger 6.5-inch screen. Then there's MyGig, an entertainment system that includes a 20-gigabyte hard drive for storing music and pictures, a built-in Gracenote music database and voice-memo recorder, and a UConnect Bluetooth hands-free phone interface.
A new Luxury Group package brings to the Limited a sunroof, a 276-watt Boston Acoustics sound system with six speakers, the MyGig entertainment system, California Walnut wood trim, remote start, LED interior illumination, SmartBeam headlamps, and rain-sensing wipers. The Luxury Equipment Group II is available on the 300C and brings several top luxury features including adaptive cruise control, puddle lamps, an auto-dimming passenger-side mirror, heated back seats, and California Walnut trim.
For those who want even more performance, there's the more exclusive SRT8 model, which includes a 425-horsepower, 6.1L version of the Hemi V8, a specially calibrated AutoStick five-speed automatic, a lowered sport suspension, and performance-tuned ESP stability control. Big 20-inch wheels, a functional hood scoop for added cooling, Brembo vented brakes, and larger dual chromed exhaust tips are also included. Inside, the SRT8 includes performance suede seat inserts, LED interior lighting, and an electronic vehicle information center.
