Allpar probably has the most thorough coverage of the upcoming and highly anticipated 2015 Dodge Challenger. The big story is the new Hellcat 6.2 liter supercharged Hemi, which is rumored to produce a whopping 660 horsepower and 640 lb-ft of torque. Other changes will include an 8-speed automatic and a refreshed interior complete with some of the modern electronics and gadgets found in other Chrysler products (UConnect 2, a backup camera, etc.). Exterior changes will probably be somewhat minor, though the Hellcat will require added air intakes. We will keep you updates as we learn more.
