The all-new 2012 Dodge Charger will once again receive a slight makeover later this fall, although this time it'll get musclecar mascara from Chrysler's Street and Racing Technology (SRT) team. Not only is the new 2012 Dodge Charger SRT8 more powerful than the last go-fast rendition, but according to preliminary test data, it's more efficient, too.
The new SRT8 Charger's improved efficiency is achieved in part by the addition of Chrysler 200 adaptive valve exhaust system and Fuel Saver technology. The latter switches the all-new 6.4-liter Hemi V-8 into a four-cylinder mode that's activated over a wider rpm range, thus minimizing consumption. By exactly how much has yet to be announced, but for a reference point, the last Challenger SRT8 powered by the 6.1-liter V-8 was rated 13/19 mpg city/highway. An active intake manifold and high-lift camshaft on the 2012 Charger SRT8 optimize low-end grunt for even more speed when you want it.
