The improvements are due to more efficient engine cooling and the application of a couple of new technologies, including variable valve timing (VVT) to boost power and torque levels throughout the rev range, while fuel efficiency is boosted by Chrysler’s fuel-saving Multi-Displacement System (MDS).
Numerous other hardware upgrades were implemented to build on the quality, reliability and durability of the engine. These include crankshaft structural upgrades, a dual-mass crankshaft damper, floating pin piston design, valve spring design and an oil pump capacity increase for VVT.
Additionally, there are several non-mechanical changes for the 2009 Dodge Charger, including a new 'Deep Water Blue Pearl Coat' paint replacing the 'Steel Blue Pearl Coat'. All models also receive a new tail lamp design, and the antenna moves to the rear window, while the Dodge Charger SE now comes standard with aluminum wheels.
The interior of the Dodge Charger SE has also been refreshed, now featuring upgraded interior accents including satin silver door trim spears, center console cup holder rings and center stack and shifter bezels. There is also a new trunk cargo net and scuff plate, as well as premium 18-ounce floor mats.
The 2009 Dodge Charger will also be able to inform the driver when it is in two-wheel-drive or all-wheel-drive mode, as well as when it is using the MDS system by displaying relevant symbols in the dashboard.
There are also new LED-illuminated door map pockets available, as well as lit up front cup holders.
Meanwhile, the range-topping Dodge Charger SRT8 gets an even more extensive list of updates, including dual-zone automatic temperature control, automatic headlamps, one-touch up/down windows, new front-seat head rests, remote start, air filtration and heated front seats, all as standard.
The SRT8 model also gets a new ABS/ESP calibration with brake knockback mitigation, and a re-tuned suspension including a knuckle and shock valve for improved handling.
There will also be a limeted edition Super Bee “buzz model” in Hemi Orange with a serialized dash plaque. The Super Bee package also includes custom wheels with black anodized pockets, exterior decals for the hood and “Super Bee” on the rear quarter, and silver Brembo brake calipers.
