Sharing platforms and powertrains with the Chrysler 300 and Dodge Charger sedans, the Magnum wagon strikes an inimitable pose with its wide track and sharply tapered roofline. For 2007, Magnums equipped with the optional 5.7-liter HEMI V-8 can be upgraded with a Road/Track Performance Group that includes performance-tuned suspension, braking, and steering, 20-inch chrome-clad wheels, and 245/45ZR20 all-season performance tires. R/T models also get standard Sirius satellite radio and all trims get an automatic oil-change alert system and sunscreen privacy glass. Eight new colors are available, including TorRed. Base SE (and rear-wheel-drive-only) Magnums have a 2.7-liter V-6 rated at 190 horsepower; next up is a 3.5-liter V-6 and 250 horsepower — available in the mid-level STX and with or without all-wheel drive. Both V-6 engines come with four-speed automatic transmissions. The 5.7-liter HEMI V-8 offers 340 horsepower in R/T models and comes with a five-speed automatic and cylinder deactivation technology to improve fuel efficiency. AWD is available with the V-8 and also gets you 19-inch wheels. Last year, an SRT8 version of the Magnum became available with a 6.1-liter V-8 and 425 horsepower. It carries over into 2007 unchanged and comes with 20-inch rims, sport-tuned suspension, and other chassis and trim/appearance upgrades. A back-seat DVD entertainment system with Kicker Mobile Surround Sound is available in SRT8 models for 2007.
