2015 Dodge Viper getting small increase in power

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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

New Viper 'is a possibility,' Sergio Marchionne says

It was thought the door to the future for the Dodge Viper had closed last year, but Fiat Chrysler CEO Sergio Marchionne reopened it during his press conference at the 2016 Detroit Auto Show. Marchionne said the current Viper is the only FCA product to use the ZD platform, which "doesn't make sense to me." Yet, "given the architectural development within the brand, there is a possibility that a new version of the Viper may surface." Automobile reports that the company uses a versatile, rear- and all-wheel drive Giorgio platform for Alfa Romeo and Dodge. It will support the Alfa Romeo Giulia (Alfa Romeo's larger BMW 5 Series competitor), the next-generation Dodge Challenger, Charger, and rumored Barracuda, and it could support a new generation of Viper. We're probably talking about a different kind of Viper, though, with Automobile saying, "the current car's truck-based V-10 no doubt would be scrapped along with its platform." A Viper without a V10 doesn't seem like a Viper to us, but we'll wait to see what happens. In the midst of contract negotiations for a new labor agreement between FCA and the United Auto Workers last year, it emerged that the Conner Avenue Assembly plant that builds the Viper hadn't been given any new product after the end of Viper build-out in 2017. That led most to reason that the current Viper would be the end of the 25-year run of America's hairiest sports car. How long we'll be waiting is unknown. Marchionne had no timetable and admitted that a future Viper might not appear on the heels of the current one. With a renewed commitment to being debt-free by 2018, FCA is likely more focused on getting Alfa Romeo running properly and cranking out the volume variants for the Giorgio platform first.
