Dodge is set to introduce a mild update for its Challenger for the 2015 model year, an update that's expected to include the addition of a new supercharged HEMI V-8 for the range-topping SRT model. The new supercharged HEMI V-8, which has been nicknamed the Hellcat, is believed to be a 6.2-liter unit, and according to some recent comments from SRT boss Ralph Gilles it may just be more powerful than the 640-horsepower V-10 in the Viper supercar.



"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,” Gilles told Hot Rod magazine. “So we have an internal horsepower race as well as an external one."



The Challenger SRT with the Hellcat will likely be a special model, similar to the 2014 Chevrolet Z/28 which is priced at $75k. This means pricing will probably fall well north of even the Challenger SRT 392’s $46k starting price, which makes sense if the car ends up the most powerful in SRT’s lineup.



The good news is that the mighty mill is expected to end up in other SRT products. Let’s hope one of them is a hardcore Viper developed along the lines of the GTS-R racing version; such a car might just be the ticket to dethroning the 2015 Corvette Z06 in the American supercar wars.



Stay tuned for an update.
