The Dodge Challenger SRT8 has always been a little lackluster but that could soon be changing as the company is reportedly developing a supercharged 6.2-liter HEMI V8 engine codenamed "Hellcat."

The Dodge Challenger SRT8 has always been a little lackluster but that could soon be changing as the company is reportedly developing a supercharged 6.2-liter HEMI V8 engine codenamed "Hellcat."

Set to debut in the next-generation Challenger, the high-performance engine will reportedly have an output somewhere in the neighborhood of 640 bhp (477 kW). If this figure pans out, the engine could be as powerful as the 8.4-liter V10 that powers the SRT Viper. More importantly, it would easily exceed the 580 bhp (432 kW) created by the supercharged 6.2-liter V8 engine that resides in the Chevrolet Camaro ZL1.

Little else is known about the engine, but an engineer reportedly described it as "last hurrah" before more stringent corporate average fuel economy (CAFE) standards kick in and begin to limit what automakers can offer.

The next-generation Challenger is expected to go into production in mid-2014, so expect to learn more about the model in the coming models.
