2015 Challenger SRT Hellcat M6
Shortly after I bought my 2015 HC, a buddy of mine asked about the stated and actual horsepower (BHP and RWHP). I gave him the factory numbers and mentioned that actual HP would probably be less, as has been my experience with other Challenger models. Today he sent me a link to an article published in late 2014 by Torque News. The numbers are surprising.
The folks from Motor Trend recently took the 2015 Dodge Challenger SRT Hellcat to the dyno at the K&N Engineering shop and they found that the official figures 707 horsepower and 650lb-ft of torque are underrated – possibly by a whole lot.
