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.

2013 Dodge Challenger R/T Redline revs into Chicago

When Dodge released the Challenger Rallye Redline last year, it brought a new dimension of styling to the car's classic muscle car lines, but it was only available in V6 form lacking the oomph to back up its sinister appearance. To remedy that situation, Dodge is unveiling the Challenger R/T Redline, powered by a Hemi V8 engine, at the Chicago Auto Show.
Other than the extra cylinders, most of the R/T's Redline package carries over from the Rallye model including the custom-look 20-inch black chrome wheels with red paint accents, but the R/T version of the package gets more of a retro look to the side stripes with graphite graphics featuring Redline lettering. Cars equipped with the six-speed manual transmission will get a performance-tuned, low-restriction exhaust allowing the engine to produce 375 horsepower and 410 pound-feet of torque; cars with the five-speed auto are rated at 372 hp and 400 lb-ft, but they do offer a bright chrome Mopar t-handle shifter and steering wheel paddle shifters.
The R/T Redline Group is offered only on cars painted in Billet Silver, Granite Crystal, Bright White and Pitch Black, and it adds just $1,995 to the MSRP of the Challenger R/T (starting at $31,990) and the Challenger R/T Plus (starting at $33,990), which adds features like Nappa leather and Boston Acoustics speakers.

Dodge Challenger ADR prototypes spied with massive rubber

In an effort to give the Dodge Challenger one last hurrah before making the switch to the Giorgio platform in 2018, Automotive News reports that the automaker will come out with the Challenger ADR. The ADR, which stands for American Drag Racer, is expected to be a wide-body, Hellcat-powered variant that is closely based off of the current model. The report seems to have merit, as photographers have captured Challenger prototypes testing with massive tires. The prototypes look extremely similar to the current Challenger SRT Hellcat with the same hood scoop, front fascia design, rear spoiler construction, and rear end. The white and purple vehicles, though, are wearing extremely wide tires. The extra-wide rubber on the prototypes appear to have a similar tread design as the ones found on the Dodge Viper ACR, which features the grippy Kumho Ecsta V720. While the ACR wears 295 mm tires at the front, the car's rear tires are massive at 355 mm. The tires found on the prototype don't appear to be as large as the ones found on the ACR, but are expected to be larger than the current Challenger SRT Hellcat's, which are Pirelli P Zero Neros measuring 275 mm at all four corners. The Challenger ADR, with its wider, stickier tires is expected to cater to drivers that are looking to put all of the supercharged 6.2-liter V8's power to the ground. The rear-wheel-drive ADR is expected to come with a wide-body kit, which is missing from the prototypes. The Hellcat-powered, wide-body Challenger ADR is expected to make an appearance later in 2017, with an all-wheel-drive model (sans Hellcat engine) known as the GT AWD following closely thereafter.
