Having just introduced an all new Dodge Charger, Challenger and Chrysler 300 for 2011, all three models are set to get an important update for 2012 under the hood. The engine will remain unchanged, but models equipped with Chrysler Corp's new 3.6L Pentastar V6 will get a significant jump in fuel economy and notably improved drive quality thanks to the addition of an 8-speed automatic.
As for the R/T and 300C models, they will retain the current 5-speed auto-box, as will a budget-priced Challenger SE model.
Chrysler is expected to add a higher-gear transmission to its V8-powered models in the future as well, replacing the current 5-speed unit. There's also a solid chance the new 8-speed could be used in vehicles like the Jeep Grand Cherokee and Dodge Durango.
