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.

Weekly Recap: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.

Mopar Hellephant crate engine sells out in 48 hours

This happened so quickly that we're only just catching up with it. Mopar opened pre-orders on the 7.0-liter Hellephant Hemi crate engine on April 26, which is Hemi Day. According to Allpar, hubbub on social media not long after that day claimed Mopar had gone through all of its Hellephant stock. When Allpar asked Fiat Chrysler for clarification, a spokesperson e-mailed, "Given the high demand and the hand-built, time-intensive build process, we have closed preordering for the 426 Hellephant Supercharged HEMI crate engine. Based on preorders, the engine sold out in just two days. Customers can visit www.cratehemi.com to receive future information and updates on the 'Hellephant' engine." No one is certain how many engines Mopar sold. Allpar wrote, "Industry insiders believe Mopar may be making around 100," but reiterated that it's a guess. The engine and the ordering process have their peculiarities. Mopar Insiders explained that Tool Engineering International helped create the 426-cubic-inch block, and that the Hellephant engine "shares nothing except for displacement with the rumored upcoming 7.0-liter 426 Hemi V8." On the Hellcat.org forum, a poster wrote that the engines "can only be sold through a dealer and that the dealers can only order 1 engine per week." The Hellephant doesn't come with Mopar's three-year, 100,000-mile warranty, either. During a press briefing last October, FCA officials said they weren't sure about offering any warranty. Based on the motor being given a part number starting with the letter P, there is a bit of protection, but it's a 90-day limited warranty covering "defects in materials or wokmanship," and only applies to engines not used in competition. For those who didn't get the opportunity to drop $29,995 for 1,000 horsepower and 950 pound-feet of torque, the best bet is to hope for the return of Apollyon's pachyderm. Motor1 wrote that "Rumors hint at... another limited run scheduled for next year due to overwhelming demand." That's thin thread to hang a Hellephant from, but it beats bupkis.
