Chrysler adds a long-wheelbase body style to this luxury-oriented sedan for 2007. 300 shares its underskin design with the Dodge Charger sedan and Magnum wagon. It comes in base, Touring, 300C, and 300C SRT8 models. All are available with rear-wheel drive. Touring and 300C models are also available with all-wheel drive. Optional for those models is the W.P. Chrysler Executive Series package that includes the long-wheelbase body. It adds 6 inches to wheelbase and to rear seat leg room. The base 300 has a 190-hp 2.7-liter V6, the Touring a 250-hp 3.5-liter V6. The 300C and SRT8 use 5.7- and 6.1-liter versions of Chrysler's Hemi V8, with 340 hp and 425 hp, respectively. Exclusive to the 5.7 V8 is Chrysler's Multi-Displacement System cylinder deactivation. The base 300 has a 4-speed automatic transmission; all others use a 5-speed automatic. The SRT8 has specific brakes and suspension. ABS and traction/antiskid control are optional on the base 300, standard otherwise. Curtain side airbags are optional, as are a cell phone link and DVD entertainment. Also new for '07 are available heated rear seats and adaptive cruise control.
