Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point.

This incredibly '90s Dodge Ram video shows roots of the luxury pickup truck

To paraphrase the Talking Heads, you may find yourself behind the wheel of a Ram 1500 Limited with a 12-inch touchscreen and sumptuous leather, and you may ask yourself, "How did we get here?" Well, some of that credit goes to that loaded Ram's predecessor, the second-generation Dodge Ram. As you'll see in this fascinating promotional video for the truck uploaded by YouTube Channel TheClassicSports, it seems to highlight all the things that make up the modern pickup truck, albeit in a slightly more modest form. Right off the bat, the video starts talking about how the new Ram isn't your traditional pickup. It has features like anti-lock brakes, a spacious, comfortable cabin and standard driver-side airbag. Later, it notes the extensive sound insulation, as well as the cupholders and a giant center console to set up your mobile office, with space for a cell phone and laptop.  But it's not just a comfortable truck. It's a powerful, practical and intimidating one. This Ram is frequently credited as the truck that changed pickup design, moving from simple rectangular boxes to ones with style, particularly semi-truck style. In the video, the host notes that regardless of what people think, "They all call it 'big'." And of course, there's the all-important utility aspect. Highlights include various interior storage bins, slots in the bed to create divided sections, and the critical towing and payload capacities; best-in-class of course. Don't forget the wide array of engines, too, from the base V6 to the unique at the time gas V10 engine. This isn't to say that competitors from Chevy and Ford weren't changing to this more stylish, more well-appointed truck philosophy, either. The mid-'90s Silverado was quite modern, too, with its sleek, if still boxy shape. And the late-'90s F-150 ushered in a sleek, curvy design that has yet to return to the full-size market. But the second-generation Ram really encompasses everything about how the truck market was about to change for the next few decades. Related Video:

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.
