The option (which could possibly come in kit form to be installed at the dealer) will be offered on 2013 model year cars, and, if the rumor holds true, it comes with another upgraded feature to help meter out the extra go-fast energy. Chrysler will fit the four door sports cars with an eight-speed automatic transmission. We sure hope this all pans out.
Currently, this super extra only applies to the SRT vehicles riding on the LX platform. That means the Jeep Grand Cherokee SRT8 isn't slated to get the upgrade. The Dodge Challenger rides on a modified LX platform known as the LC, but rumor has it the power boost will be available for that model as well.
