Since the automotive world first learned that the Dodge Challenger would eventually be powered by a supercharged Hemi nicknamed the Hellcat, there have been long discussions pertaining to how much power this new Hemi will make - and recent comments by SRT boss Ralph Gilles has spiced those discussions up even more.

While speaking with Hot Rod Magazine, SRT CEO Ralph Gilles made this intriguing comment that has spurred new discussions about the power output of the Hellcat Hemi powered Dodge Challenger: "We have a situation where, you know-- we may have a situation--where the flagship car is not the most powerful car in our arsenal. So we have an internal horsepower race as well as an external one."
Just to be clear, the flagship car for both the SRT brand and the Chrysler Group as a whole is the 2014 SRT Viper. The Viper is powered by an 8.4L V10 that produces 640 horsepower and 600lb-ft of torque so if it were not the most powerful car in the arsenal, that would indicate that the next generation SRT Challenger packing the new supercharged Hellcat Hemi will offer more than 640 horsepower.
Current speculation across the various social networking sites and enthusiast community forums suggest that the Hellcat Hemi will be a supercharged 6.2L V8 with as much as 680 horsepower. That number seems to be incredible almost to the point of being unbelievable, but we should keep in mind that the likely goal of the SRT engineers in developing the Hellcat Hemi powered SRT Challenger is to be the most powerful American muscle car ever.
To this point, the most powerful American muscle car (or American full factory production car in general) is the current Ford Shelby Mustang GT500. That supercharged monster packs a 5.8L V8 that makes 662 horsepower and 631lb-ft of torque with the current SRT Viper ranking second with 640 horsepower and 600lb-ft of torque and the C6 Chevrolet Corvette ZR1 slips in third with 638 horsepower and 604lb-ft of torque. The most powerful Chevrolet Camaro is the ZL1, with 580 horsepower and 556lb-ft of torque.
Even if the Hellcat Dodge Challenger has only a shade more power than the SRT Viper – say 650 horsepower and 610lb-ft of torque – it would create the internal horsepower race that Gilles referenced, but it wouldn’t make the Challenger the most powerful muscle car ever. With that in mind, I expect that SRT may actually aim for the 680hp figure as to give the brawny Challenger a comfortable advantage in power over the GT500 Mustang.
Considering that the other SRT Hemi V8s have had very similar horsepower and torque figures, there is a good chance that the 6.2L Hellcat Hemi will also have a massive lead in torque over anything else sold in the US outside of heavy duty diesel pickups.
While there has been some question lately as to when we will meet the 2015 Dodge Challenger and the new SRT Hellcat Hemi, I still have my fingers crossed to see the next Mopar muscle car – and possibly the most powerful muscle car ever – at the New York Auto Show next month.

Chrysler needs to make a V10
Chrysler needs to make a V10 version of the 6.2 litre Hellcat engine for the Viper. That would not only solve the "out power" issue of the Challenger vs Viper,but obviously reduce fuel consumption of the Viper too because the new V8 engine would be more fuel efficient in the Challenger than the previous one and would carry the quality with a V10 version over the current one used.That would also reduce development cost using the new V8 technology for a new V10.Then production costs can be reduced while quality and fuel economy are improved-discontinue the cast iron Hemi in all Chrysler vehicles and current V10 (when new one is developed for the Viper)once production of the new aluminum hemi begins for the Challenger and retrofit the V8 version of those vehicles that use the current Hemi.Those vehicles would also benefit from reduced frontal mass with the aluminum engine too.
