probably about 117 MPH as it's limited by the computer. The performance delivered by the 2009 Dodge Challenger supports its styling. Three engines are available. The ultimate 6.1-liter HEMI, producing 425 horsepower, is the top powertrain and only available in the SRT-8 edition. The SRT designation identifies this Challenger as having been enhanced by Chrysler's in-house tuning gurus, the Street and Racing Technology group. New for 2009, the Challenger SRT8 can be equipped with a six-speed manual. Carried over from 2008, a heavy-duty five-speed automatic is available. Performance is impressive, with a top speed of more than 170 mph. http://www.thecarconnection.com/bottomline/dodge_challenger_2009
