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.

Mopar '13 Dart will roll into Chicago next week

We think this officially counts as a tradition. Every year going back to 2010, Mopar has rolled out a limited edition version of a popular product from the Chrysler Group portfolio. First it was the Mopar '10 Challenger, then the Mopar '11 Charger, then last year's Mopar '12 300, and this year it will be the Mopar '13 Dart, which will make its official world debut next week at the 2013 Chicago Auto Show.
Limited in number to just 500 units, the Mopar '13 Dart is no mere appearance package, though the demeanor of the Dart will be murdered out with a gloss black finish, gloss black 18-inch wheels, a set of Mopar blue stripes and a mean-looking Mopar ground effects kit. Likewise, the interior is touched up with leather seats (a blue one for the driver and black hides for the passengers), gloss black and black chrome trim, blue accent stitching, a sport pedal kit and other Mopar interior accessories.
Turning our attention back to the mechanical bits, the Mopar '13 Dart comes with the car's most powerful engine, a turbocharged 1.4-liter MultiAir four (shared with Fiat 500 Abarth) that's paired with a manual transmission. Those big, black wheels get wrapped in low profile 225/40R18 performance tires, and keeping everything in check is an upgraded brake kit with slotted rotors. The steering has also been calibrated for performance, the suspension lowered seven millimeters, and the exhaust tuned for better engine breathing.

Chrysler readying Hellcat V8 with Viper-like power

A monstrous supercharged V8 engine could be in store for Chrysler and SRT products, if recent rumors are to be believed. Allpar is reporting that the forced-induction V8 - Chrysler's first, if this goes down - could make its debut this summer.
The story goes that the Hellcat would be based on a 6.2-liter Hemi engine, rather than on the existing 5.7- or 6.4-liter versions of the company's vaunted mill. In any case, the general consensus is that the motor will have gobs of power. Modest estimates call for between 500 to 570 horsepower, with some outliers predicting a figure as high as 600 hp. That figure would put the output would place the Hellcat awfully close to that of the 640-hp V10 in the SRT Viper, too. Allpar contends that a slightly lower powered version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot.
The Hellcat could debut in a number of SRT products. SRT versions of the Charger, Challenger and 300 are all up for grabs, as is the rumored SRT Barracuda.
