After months of declining to confirm its existence, Chrysler Group executives last week proudly displayed a new supercharged Hemi V-8 that they will install in some high-end Dodges.
Known internally as the Hellcat, the 6.2-liter engine puts out power that rivals or exceeds the 640 hp of the Viper's naturally aspirated V-10, according to earlier hints from the company.
The new V-8 is planned for 2015 SRT versions of the Dodge Challenger and Charger, according to information from Dodge brand chief Tim Kuniskis.
The engine will give Dodge competitors to the 662-hp Ford Mustang Shelby GT500 and 580-hp Chevrolet Camaro ZL1.
And like those cars, the Dodge models are likely to be priced well above $50,000.
