The performance sedan from Chrysler rides on the same chassis as Concorde, although for 300M the platform stretches longer as wheels pin to corners. The result: A stiff and balanced structure that produces crisp handling traits. New editions include the 300M Special, a souped-up version with one-inch drop in ride height, 18-inch chromed aluminum wheels and low-profile Michelin Pilot tires. The Special packs a 3.5-liter V6 with single cam configuration. Special tuning pushes output to 255 hp. It delivers dynamic power yet still operates on regular gas and earns respectable fuel economy figures. The plant teams with an electronically-controlled automatic four-speed tied to the AutoStick. Other special hardware includes beefy disc brakes with computerized connections to anti-lock and low-speed traction controls, and, to cast clear light on a dark road, high intensity discharge (HID) xenon quad headlamps. Regular 300M uses a 3.5-liter V6 worth 250 hp with an automatic. 300M is the first Chrysler to offer subscription-based satellite radio service through the Sirius network.
