The Chrysler 300 luxury sedan receives some significant changes year. The biggest, literally, is the introduction of a new long-wheelbase model. The W.P. Chrysler Executive Series Package (available on Touring and 300C rear-wheel-drive models) adds 6 inches to the 300’s wheelbase.The extra length is used to provide substantially more rear legroom. New features this year include adaptive cruise control, automatic high-beam headlights, restyled 18-inch chrome-clad wheels, heated rear seats, a maintenance reminder and supplemental turn signals mounted in the exterior mirror housings.

The rear-drive 2007 Chrysler 300 is a large sedan available in four trim levels. The base 300 comes with air-conditioning, a power driver seat, a CD player, cruise control, remote keyless entry and a tilt/telescoping steering wheel. The Touring adds a bigger V6, alloy wheels, foglights, leather upholstery and heated mirrors. The 300C adds a Hemi V8, an upgraded 276-watt Boston Acoustics sound system, foldaway mirrors, power-adjustable pedals, rain-sensing wipers, premium leather trim, a power tilt-and-telescoping steering column and a driver memory system. This trim also offers SmartBeam headlights, which automatically activate or dip the high-beam headlights based on road conditions.

The high-performance SRT8 model features a more powerful V8; a rear spoiler; sport-tuned suspension; a stability control system that allows more aggressive driving; 20-inch alloy wheels; and Brembo performance disc brakes with four-piston calipers. Depending on trim, include xenon headlights, Bluetooth connectivity, a sunroof and a rear-seat DVD entertainment system. A navigation system is available on Touring and 300C models, as is all-wheel drive. Those looking for more room can opt for the W.P. Chrysler Executive Series Package (available on Touring and 300C rear-wheel-drive models), which adds 6 inches to the car’s wheelbase and a lot more space for rear-seat passengers.

Features like ABS, traction control and stability control are optional on the base 300 but standard on all other trims. Full-length side curtain airbags are optional on all models. In NHTSA crash testing, the 2007 Chrysler 300 earned a perfect five stars for frontal-impact protection. In side-impact tests, it earned four stars for front-occupant safety and five stars for the rear. It earned a “Good” rating — the highest possible — in IIHS frontal-offset crash testing.
