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.

Dodge Viper to out-Hell the Hellcat with supercharged V10?

The Viper wouldn't be the Viper if it wasn't the most powerful model under the Chrysler umbrella. But with the arrival of the Hellcat engine in the Dodge Charger and Challenger, the Viper has fallen behind in the bragging rights department: where the new supercharged V8 produces 707 horsepower and 650 pound-feet of torque, the naturally aspirated V10 offers "only" 640 hp and 600 lb-ft - gargantuan output figures by almost any other standard, but crucially behind on the SRT power scale. Conner Avenue is going to have to do something about that.
Although the Hellcat's engine reportedly won't fit under the Viper's hood, SRT is now rumored to have another trick up its sleeve: supercharge the existing V10. According to the Pentastar performance enthusiasts at allpar.com, Chrysler has already taken delivery of the first such prototype engines so that it can begin the process of fitting it into an upgraded Viper.
The spooled ten-pot is tipped to produce around 800 hp and 650 lb-ft of torque. More than that and the Viper's drivetrain, chassis and bodywork would have to be substantially reworked. Though beefier transmissions are available, fitting them would reportedly set off a domino-game of changes required to handle the added torque. Which may be something Chrysler would be prepared to do for the next-generation model, but in the meantime, 800 hp could prove enough to put the Viper back atop the Mopar performance ladder where it belongs, and give it an edge against the new Corvette Z06 to rekindle sales.

Weekly Recap: FCA hit with record fine as NHTSA crackdown continues

The National Highway Traffic Safety Administration slapped Fiat Chrysler Automobiles with a record fine this week that could reach $105 million. The punishment comes after NHTSA found problems with the automaker's execution of 23 recalls that affect more than 11 million vehicles. The consent agreement, announced Sunday, calls for FCA to pay a $70-million cash fine and requires the company to spend at least $20 million over a three-year period on industry outreach programs and to beef up old recall campaigns. Failure to comply will result in another $15-million fine. FCA also agreed to federal oversight, which includes an independent monitor to oversee the company's recalls. The $70-million cash fine equals a penalty NHTSA levied on Honda in January. "Fiat Chrysler's pattern of poor performance put millions of its customers and the driving public at risk," NHTSA administrator Mark Rosekind said in a statement. "This action will provide relief to owners of defective vehicles, will help improve recall performance throughout the auto industry, and gives Fiat Chrysler the opportunity to embrace a proactive safety culture." FCA called the deal a "consensual resolution," but admitted that it "failed to timely provide an effective remedy" during certain recalls. "We are intent on rebuilding our relationship with NHTSA and we embrace the role of public safety advocate," the company said in a statement. The announcement kicked off a busy week for the automaker. NHTSA agreed FCA did not need to recall 4.7 million vehicles after an investigation failed to find defects with a power module used in some Jeep, Dodge, and Ram vehicles. A Georgia judge also reduced a civil verdict involving a death in a Jeep Grand Cherokee crash. Amid all of that, the company reported net profit of about 333 million euros, or $364 million in the second quarter on Thursday. OTHER NEWS & NOTES FCA ramps up Hellcat production Despite a decidedly legal and financial week for FCA, there was still time for the performance side of the business to briefly grab the spotlight. The automaker is more than doubling its production of the Dodge Challenger and Charger SRT Hellcats in response to strong demand. The order bank opens the second week of August and production begins in September. FCA will finish up its scheduled 2015 model-year Hellcat builds, and cancel any "unscheduled" versions, though customers will get discounted pricing for 2016.
