Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.

Dodge whips covers off 2013 Blacktop series

Dodge introduced us to its Blacktop model lineup a year ago with the 2012 Charger and followed up with more recently with the 2013 Challenger and 2013 Avenger. Now the automaker will be applying this ominous-looking treatment to the Durango, Grand Caravan and Journey models for 2013 as well. These models will be unveiled next week at the Detroit Auto Show, but Dodge has released most of the details for these new products including pricing and availability.
If the Grand Caravan R/T (aka, the Man Van) wasn't aggressive enough for you or its $30,000 starting price was a little too pricey, then the 2013 Grand Caravan Blacktop could be the ticket. Starting with the SXT trim level (which stickers at $19,995), the Blacktop package costs only $595, and adds unique features such as blacked-out headlights, grille and fog lights bezels and an all-black interior. The van rides on black-accented, 17-inch aluminum wheels. The Grand Caravan Blacktop is only available in monochromatic paint schemes limited to Billet Silver, Brilliant Black, Maximum Steel, Redline Red and Stone White
Likewise, the 2013 Journey Blacktop is offered only on the SXT model (starting at $18,995) with all of the crossover's normal options such as four- and six-cylinder engines, five- or seven-passenger seating and front- or all-wheel drive. The Blacktop package adds $995 to the Journey SXT's price and features many of the same black accents as the Grand Caravan like the headlights, grille, door mirrors and lower fascia. Exterior colors are limited to Bright Silver, Bright Red, Brilliant Black, Brilliant Red Tri-Coat, White, Pearl White Tri-Coat and Storm Grey, and the package's 19-inch wheels come in Gloss Black. Inside, the Journey Blacktop comes standard with black cloth seats and Chrysler's 8.4-inch Uconnect touch screen, but black leather is also available as an option.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
