The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.

The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.

The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line – which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.

Chrysler's big-bore V10 engine has come a long way from the 400 horsepower it produced back in 1992, increasing displacement by only 24.5 cubic inches but power by over 60 percent over the past 22 years.

      "....but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line." Not mention the corners as well. The Challenger HC would get eaten alive on a road course by a Viper.

        It should, without apology. Challenger is a muscle car with good handling and gobs of power. Viper is a race breed pure sports car. What they both must represent and achieve is best in class credential and affordable performance. As a Corvette is priced as a Chevy. Viper needs to be priced more like a Dodge. Viper and Challenger are horses of a different color, even if they are both "Dodge Red".

      Too little too late. If they don't change course drastically, the management at Fiat are going to run out of patience quickly.

        Poor Viper. Can't go up in HP cause it will threaten Ferrari. Can't go down in HP cause the customer will ignore it. I see the Vipers obituary fast approaching on the horizon.

      NOT the thing to tweak to promote sales.

      I think the Dodge Viper will need a totally new platform and radical new philosophy. That platform must accept the Hemi , the Hellcat and the V-10. In addition, Dodge needs a totally new philosophy that incorporates the new engines, automatic transmissions, including a Hemi powered, automatic, entry level Viper for around $70,000, a Hellcat powered and automatic Viper GT and a supercharged V-10 with the six speed for the SRT Viper. Styling must be a radical departure from the current out of step retro look and tap into some Ferrari styling cues. I see nothing wrong with some cross Atlantic help from their Italian cousins. Viper will not be around for long without a new platform, much bolder styling and a new marketing strategy that makes Viper more affordable and more flexible in drive train assets. The next Viper must be not just new.....but totally all new.

        Bill-I agree with you. Either that or they simply have to lower the price to make it corvette competitive.

        Agreed. The retro styling has pretty much run its course. It needs a more up-to-date look.

        Pleased to see some folks agreeing with my thoughts. I don't see or want Viper to sell or be marketed the same way as Corvette, an absolutely unique product, but as a halo car for Dodge and it's positioning as an affordable performance brand, it desperately needs a lower priced model, more flexible power train assets, and triple the sales to survive. Let's be honest, this rendition has fallen flat and a whole new approach and perhaps a restructured "Viper management team" is needed here. Time to go all in or, so sadly, be forced out of existence.

        Exactly what I was thinking about the corvette !

      I like the Viper. It's a shame it doesn't get the interest it deserves. But it is quite expensive, I think they may need to make a smaller car.

      It's just not American enough, especially compared to the Corvette. This new Vette is amazing to drive, has better interior(despite being available in ugly blue leather), and is an amazing convertible that looses none of it's performance after it looses the roof. And is much cheaper, at least the non z models, and actually has a decent trunk space. Only way to make Viper sell is to really macho it up.

      The raw nature of this car, 6 speed manual, and it's exclusivity is enough to convince me to get a Viper over a Vette/Porsche despite the price difference. I finally saw a new Viper on the road the other day and it just turned heads EVERYWHERE. The sound note was incredible. You really have to see this car to appreciate it.

      I don't think this is really worth advertising when it's little sister just got got a 232HP bump from 475HP to 707HP.

      The Z06 is going to be a performance mother. Everyone knows it. Its going to be epic. Then we all know there is going to be a track focussed naturally aspirated Zora with a high revving motor after that.
