Months ago, sources told Allpar about a new Hemi V8 coming down the pike for SRT cars; set to debut in the SRT Barracuda, which at the time we believed was either a replacement for the Challenger or an SRT variant of the Challenger (the latter still seems likely), the “HellCat”  V8 will go up against supercharged Ford and GM powerplants.

While Chrysler has made numerous turbocharged engines — mainly 2.2 or 2.5 liter four-cylinders, but also two completely different 2.4 liter four-cylinders for SRT cars — this will be both the company’s first supercharged production engine, and their first forced-induction V8. It will reportedly include the cylinder-deactivation technology which debuted in the 5.7 Hemi and is now in the SRT 6.4 Hemi.

According to (now-defunct) Ontario Street Car, we can now expect the engine to be sold this summer, with production starting in April. The name follows aviation history, with the 392 Hemi called Apache and the variable-cam-equipped 5.7 called Eagle. The 5.7 Hemi and 6.4 Hemi are also both rumored to be getting power updates.

While most online sources are claiming 600 horsepower for the new engine, estimates of power for new mills is often grossly overstated on rumor sites, and we expect a much more modest 500-570 horsepower. That is well above the 6.4 liter V8’s 470-475 horsepower, though far less than the output of the Mustang GT500 and  Corvette ZR1, which will likely also continue to have far higher price tags.

While originally intended for an SRT Barracuda, which is now less likely to be HellCat’s debut car, the engine is also destined for the SRT versions of the Charger, Challenger, and 300C.  Rumors on the Barracuda still swirl with the original “Challenger based” reports on one hand, and the smaller D-RWD platform on the other. Some believe the next-generation Challenger will be on an eight-inch-shorter body to cut weight.
