There's now something called the Challenger SRT Hellcat.
It's amazing just how quickly things can change. Take the Dodge SRT Viper, for instance. Only a few months ago it was the automaker's most powerful, most badass thing on four wheels. Then the Challenger SRT Hellcat with its 707 horsepower was unveiled. The Viper "only" had 640 ponies. So what to do? The answer is not much. Dodge has just announced some changes to the 2015 Viper lineup and the bottom line is this: the Challenger Hellcat remains the ultimate kick in the balls American-made horsepower champ.
The 2015 Viper's 8.4-liter V10 has been boosted by 5 hp and, thanks to further refinements to the six-speed manual, an additional mile-per-gallon on the highway (now at 20 mpg). There's also the new Viper GT model, which is a mid-range trim pack priced between the base Viper and Viper GTS. The Viper TA 2.0 Special Edition is also new, featuring more downforce thanks to a new aerodynamics package and rear wing. Building off last year's Viper TA, the track-tuned trim now has a carbon-fiber, in place of the old aluminum, structural engine X-brace under the hood. Other refinements were made to the suspension and brakes.
The 2015 Viper GTS Ceramic Blue Edition Package has also broken cover, featuring black stripes and five-spoke "Rattler" wheels along with other unique interior and exterior touches. Just 40 units are planned. Lastly, there are two new exterior colors: Stryker Purple and Yorange. The latter, as you can probably guess, is a mix between yellow and orange. So Dodge, how about that rumored supercharged V10?
