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.

Continental Automotive recalls 5 million airbag control units

Takata isn't the only supplier having airbag problems. Rival manufacturer Continental Automotive Systems announced a recall of 5 million airbag control units fitted to vehicles from Honda, Fiat Chrysler Automotive, Mercedes-Benz, and even a certain Chrysler-based Volkswagen. This sweeping recall has actually been in progress for some time, although the exact scope is only now becoming evident. In October of 2015, Mercedes-Benz recalled 2008 and 2009 model year C- and GLK-Class vehicles because their Continental-made airbag control units could corrode. Such a condition could cause the airbags to deploy without cause or warning, or in the event of a crash, not deploy at all. You can read all about it in our post from last year. Now, Continental's recall is going wide. Alongside the already recalled C and GLK, you've already heard about the 2008 and 2009 Honda Accord airbag recall, which we reported on yesterday. Now, Fiat Chrysler is announcing the recall of the 2009 Dodge Journey, as well as the 2008 and 2009 Dodge Grand Caravan, Chrysler Town and Country, and their rebadged counterpart, the Volkswagen Routan. Yes, one manufacturer is recalling another manufacturer's vehicle. The models listed above only amount to about 580,000 vehicles out of 5 million bad airbag control units. And since Continental will notify manufacturers who will then issue their own recalls, it's extremely likely that more brands and vehicles will be ensnared. Stay tuned.

Auto sales in March and first quarter down nearly across the board

Nearly every major automaker reported weak U.S. sales for March and the first quarter of 2019, citing a rough start to the year, but said a robust economy and strong labor market should encourage consumers to buy more vehicles as 2019 rolls on. GM, which no longer releases monthly sales figures, saw first-quarter sales fall 7 percent, with declines across all brands. Sales of Silverado pickup trucks fell nearly 16 percent and the high-margin Chevy Suburban large SUV dropped 25 percent. Ford also no longer releases monthly sales numbers, but is due to release its first-quarter sales figures on Thursday. According to industry data, Ford's sales fell 2 percent in the quarter and 5 percent in March. Ford representatives did not immediately respond to requests for comment. FCA reported a 7 percent fall in U.S. sales in March and a 3 percent drop for the first quarter. All of FCA's brands dropped in March, except for Ram, which saw a 15 percent increase in pickup truck sales. "The industry had a tough first quarter, but with spring finally starting to show its face and continued strong economic indicators ... we are confident that new vehicle sales demand will strengthen going forward," FCA's U.S. head of sales, Reid Bigland, said in a statement. Toyota reported a 3.5 percent fall in U.S. sales in March and 5 percent for the first quarter, hurt by declining demand for its Corolla sedans and Camry vehicles. "While some of our competitors are abandoning sedans, we remain optimistic about the future of the segment," Toyota said in a statement. Nissan posted a 5.3 percent drop in sales in March, and its first-quarter sales were down 11.6 percent. Honda and Hyundai bucked the trend. Honda's U.S. sales rose 4.3 percent in March and 2 percent in the quarter, while Hyundai's were up 1.7 percent and 2.1 percent, respectively. Passenger-car sales suffered throughout the January-March quarter compared with the same period in 2018 as Americans continued to abandon them in favor of larger, more comfortable pickup trucks and SUVs, which are far more profitable for automakers. The battle for market share in the particularly lucrative large-pickup truck market intensified in the quarter, as Fiat Chrysler Automobiles' Ram brand outsold the U.S.' No. 1 automaker General Motors' Chevrolet-brand trucks. The two automakers have both launched redesigned pickup trucks.
