For over a year, Fiat Chrysler Automobiles has been working on a Hemi V8 dubbed the Hellcat, which set to debut in a revised Dodge Challenger. However, the Hellcat could prove a challenge to the SRT Viper’s V10, possibly unseating the venerable monster from the throne.
Automotive News reports the rumored V8 has caused an internal debate within FCA, in particular what it would mean for the Viper when the Challenger receives the engine. SRT brand boss Ralph Giles told Hot Rod magazine:
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 … how do we explain that to ourselves? So we have an internal horsepower race as well as an external one.
While the Viper’s naturally aspirated V10 pushes 660 horsepower, the SRT variant of the Challenger — pitted against the Ford Mustang GT500 and Chevrolet Camaro ZL1 — is rumored to put out as much as 700 horses .
The 2015 Challenger is rumored to debut in New York next month.
