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.

Gas prices down, 707-hp engine production up... USA!

On Saturday, the United States of America will celebrate its 239th birthday. That means fireworks, barbecues, block parties, and, oh yeah, Hellcat engines and low fuel prices. The most American of (Mexican-built) powerplants, the big, loud, supercharged, 707-horsepower Hemi is slated for yet another production boost to match up with some serious demand, while the dino juice it runs on is cheaper than it's been in over half a decade. The Saltillo, Mexico engine factory already produces some 4,000 Hellcat engines each year – that's in addition to the Tigershark four-cylinder, the 5.7-liter Hemi, and 6.4-liter SRT Hemi V8s – and it's not entirely clear how many more might get added to that total. What we do know, though, is that Fiat Chrysler can't build the engines fast enough. "We're going to build more [Hellcats] for 2016," SRT boss Tim Kuniskis told Automotive News. "It's a small sliver of what we sell, but it really creates a halo for the rest of the lineup. For example, the next highest car, the Scat Pack Challenger, I have essentially a zero-day supply. It's sold out." This bit of good news comes on the back of something equally good – low summer gas prices. According to the US Energy Information Administration, the nationwide average for for "all formulations" of fuel in June sits at $2.885. Ignoring the remarkably low prices we saw in January and February of this year – figures that themselves hadn't been seen since May of 2009 – the national average hasn't sat that low since October 2010. So yes, it's a very a good time to be an American gearhead.
