The Chrysler Group has announced the official power numbers for the 2015 Dodge Challenger SRT Hellcat and with a bone chilling 707 horsepower, the Hellcat Hemi is officially the most powerful American V8 ever while also being the most powerful muscle car ever, the most powerful American production car ever and the 6th most powerful production car in the world today. In addition to packing 707 horsepower, the new Challenger Hellcat offers an equally incredible 650lb-ft of torque, which puts it in the top three in the world behind just the McLaren P1 and LaFerrari.
We have been speculating for months – maybe even years – as to how much the supercharged SRT Challenger would have when it arrived. At first, it was expected that the Hellcat would offer between 550 and 650 horsepower, most likely coming in right around the power figures of the SRT Viper. Chrysler gave us some numbers to go on a while back, announcing that the supercharged 6.2L Hemi would offer at least 600 horsepower and at least 575lb-ft of torque. I speculated that the Challenger Hellcat would likely be in the range of 625hp and 600lb-ft of torque, which would leave plenty of space for the mighty Viper, but Chrysler hasn’t shown any concern for the power exclusivity of the SRT supercar.
That power is channeled to the rear wheels by means of a new 8HP90 8-speed automatic transmission that has been beefed up compared to the 8-speed transmission offered throughout the rest of the 2015 Challenger lineup. With the help of launch control, that 707hp and 650lb-ft of torque will almost certainly make the Hellcat powered Challenger the quickest and most likely the fastest American muscle car of all time. Even though the Challenger SRT is a little heavier than the 2014 GT500, the added horsepower, torque and transmission gearing should allow the brawny Mopar muscle car to outrun the Shelby Mustang in a straight line – whether racing through a quarter mile or battling for the highest top speed.
Claims of Fame for the 2015 Dodge Challenger Hellcat Hemi:
Most Powerful American Muscle Car Ever – beating the 2014 Ford Shelby GT500 Mustang which offers 662 horsepower and 631lb-ft of torque.
Most Powerful American Production Car of All Time – In addition to besting Ford’s supercharged Mustang, the Hellcat Challenger offers significantly more power than the 2015 Chevrolet Corvette Z06 (650 horsepower, 650lb-ft of torque) and the SRT Viper (640hp, 600lb-ft of torque)
Most Powerful American V8 Ever – Even if you look through the seriously underrated V8s of the original muscle car era, none of them offered 707 horsepower and 650lb-ft of torque.
6th Most Powerful New Car in the World – The 2015 Dodge Challenger SRT Hellcat’s 707 horsepower puts it 6th among the world’s most powerful new cars on sale today. Only LaFerrari, the McLaren P1, the Porsche 918 Hybrid, the Lamborghini Veneno and the Ferrari F12 have more horsepower than the SRT Hellcat Challenger and only LaFerrari and the McLaren have more torque than the blown Hemi.
