The 2009 SRT8, while still equipped with the 6.1 L (370 cu in) Hemi V8, is virtually identical to its 2008 counterpart, with the main difference being the choice of either a 5-speed automatic or 6-speed manual transmission. Standard features include Brembo brakes, a sport suspension, bi-xenon headlamps, heated leather sport seats, keyless go, Sirius satellite radio, and forged aluminum wheels in addition to most amenities offered on the R/T and SE models such as air conditioning and cruise control. In addition, the 2009 had a "limited slip" differential that was not offered on the 2008 model. A "Spring Special" SRT8 Challenger was also offered in B5 Blue, but due to rolling plant shutdowns, just over 250 Spring Special Challengers were built before the end of the 2009 model year.
