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.

Chrysler Recalling Nearly 907,000 Cars, SUVs

Nearly 907,000 Chrysler, Dodge and Jeep SUVs and cars are being recalled for alternators that can fail and heated power mirror wiring that can short and cause minor fires. The recalls, posted Thursday by U.S. safety regulators, push the total number of recalls so far this year 544, totaling a record of more than 52 million vehicles. The largest of Thursday's recalls covers nearly 470,000 Jeep Grand Cherokees, Chrysler 300s, and Dodge Chargers, Challengers and Durangos from the 2011 through 2014 model years. The alternators can fail, causing the 3.6-liter V6 engines to stall unexpectedly. The problem also can cause the electrical system to fail, as well as knock out power-assisted steering, antilock brakes and electronic stability control. It can even cause fire or smoke, according to documents Chrysler filed with the U.S. National Highway Traffic Safety Administration. NHTSA opened an investigation into the problem in July, and Chrysler began its own probe in August. The company analyzed warranty complaints and alternators that had failed. The alternator generates electricity to recharge the battery and run other devices. Chrysler investigators traced the problem to heat fatigue in an alternator diode. Chrysler said it received 322 complaints about the problem, while 55 people complained to NHTSA. The company said it knows of one crash related to the problem, but no injuries or fires. The company will replace the alternators with upgraded versions for free. Owners will be notified in November. The company says customers who see warning lights or suspect a problem should contact their dealers. The recall affects cars and SUVs sold mainly in the U.S. and Canada, but some were sold in Mexico and overseas markets. The second recall covers almost 437,000 Jeep Wranglers from 2011 through 2013. Water can find its way into the heated power mirror wiring harness and cause corrosion. That can cause a short and could cause a minor fire and smoke, as well as cause loss of function of the mirror. The problem was discovered in February after three Wranglers in Canada were damaged. Chrysler says it has 26 complaints about the problem, but it knows of no fires, crashes or injuries. Dealers will move the wiring and install a protective shield to keep water out at no cost to owners, starting in December. Most of the Wranglers are in the U.S., Canada and Mexico, but more than 78,000 were sold overseas.

Dodge PHEV due in 2022 expected to be the Hornet

A relatively new saga involving hornets in the Pacific Northwest begins with the adjective "murder" and gets worse from there. A relatively dated saga involving hornets in the automotive industry begins with the name "Dodge" and is — or could be — much friendlier to plant and animal life. Last year, former Dodge parent company Fiat Chrysler trademarked the term "Dodge Hornet" for the first time. Two months ago, an Italian publication credited its sources with news that current parent company Stellantis will create a Dodge version of the Alfa Romeo Tonale (pictured) and call it the Hornet. Now, Mopar Insiders picked up on Stellantis CEO Carlos Tavares sharing a roadmap of the 20 PHEV and battery-electric vehicles coming our way in the next two years between the company's 14 brands. Dodge merits a single PHEV entry in the 2022 column. MI says this will be the Hornet.      As FCA recast its U.S. lineups to give Dodge more focus and give Chrysler a reason to exist, Dodge lost the Caliber, Nitro, and Journey. The way this new report is put, and as we mused a year ago, the coming Hornet will replace the Journey — a space Dodge could do well to return to. Never given much love by the parent company, the Journey turned into a hoary old thing over its 13 years on the market, but sold in remarkable numbers to the end. According to Car Sales Base, sales increased nearly every year for the first nine years of the Journey's life. Even during the sales decline over the last four years of its production life, the Journey found 298,594 homes in the U.S. More than 12,000 zombie units have been moved off lots this year. A Dodge Hornet likely wouldn't offer the Wal-Mart rollback pricing the Journey was known for. Also, the Hornet would pack in just two rows, whereas the Journey offered three. Nevertheless, we're now talking about three vehicles sharing major internal organs; the Alfa Romeo Tonale leans heavily on the Jeep Compass platform and internals, and the Dodge is expected to be built at the same Naples, Italy plant as the Alfa Romeo. The economies of scale are there. As for powertrain, we know there's a Tonale PHEV coming, but it's thought to get its plug-in system from the Jeep Renegade 4xe that's based around the smaller 1.3-liter four-cylinder with either 190 or 240 total horsepower instead of the larger 2.0-liter engine in the Wrangler 4xe.
