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.

Dodge Dart falls short of Consumer Reports Recommended, Caddy XTS and Lincoln MKS, too

The Dodge Dart, Cadillac XTS and Lincoln MKS all failed to earn a "Recommended" rating from Consumer Reports. When it came to the compact Dart, the organization's testers thought the vehicle offered a quiet cabin, solid-feeling chassis and nimble suspension, but the new model ultimately fell short of the coveted rating due to powertrain issues. The institute's reviewers found the base 2.0-liter four-cylinder engine to be underpowered and noted "drivability issues" when the available turbocharged 1.4-liter four was paired with the optional dual-clutch transmission (some of our editors disliked it paired with the six-speed manual). CR also dinged the latter powerplant for sounding "raspy." For what it's worth, we think the forced-induction engine offers an excellent and playful exhaust note, but that's just us.
As for the XTS, CR lauded the car for its luxurious cabin, but the vehicle's experience was dulled by its finicky CUE infotainment interface. Overall, the big Cadillac scored much higher than its cross-town rival from Lincoln. While testers found the American luxury sedan to offer a quiet ride and quality fit and finish, they felt the MKS delivered a "cramped driving position, ungainly handling, uncomposed ride, and limited visibility." Ouch. At the end of the day, both cars fell short of rivals from Japan, Germany and Korea. Check out the full press release below with more details, along with CR's musings on the Chevrolet Spark and Lexus ES.

CEO Sergio Marchionne curses FCA spokesman for emissions cheating denial

WASHINGTON — Fiat Chrysler Chief Executive Officer Sergio Marchionne reprimanded the company's top U.S. spokesman for issuing press releases about Fiat's vehicle emissions practices days after Volkswagen's disclosure in September 2015 that the German automaker had used illegal software to evade emissions tests, documents released Monday show. Lawyers suing Fiat Chrysler Automobiles in a securities case filed excerpts of an email from Marchionne to Gualberto Ranieri, then the company's U.S. spokesman, in a filing in federal court in New York criticizing him for saying that the company does not use defeat devices. "Are you out of your goddam mind?" Marchionne wrote in an email on Sept. 22, 2015, adding that Ranieri should be fired and calling his actions "utterly stupid and unconscionable." The company said in a statement on Monday it was "understandable that our CEO would have a forceful response to any employee who would opine on such a significant and complex matter, without the matter having been fully reviewed through its appropriate channels." The statement added that Ranieri's comments came just days after VW's emissions issue became public "and before a comprehensive internal review and discussions with component suppliers was possible." Fiat Chrysler was sued in 2015 along with Marchionne and other executives over claims it defrauded shareholders by overstating its ability to comply with vehicle safety laws. An amended version of the complaint filed in 2017 added claims about its compliance with emissions laws. The shareholders accused the defendants of inflating Fiat Chrysler's share price by hundreds of millions of dollars from October 2014 to October 2015 by downplaying safety concerns. They said the shortcomings materialized in 2015 when the automaker was fined $175 million by the National Highway Traffic Safety Administration, and took a roughly $670 million charge for recalls. Plaintiffs filed the excerpts seeking approval to take up to 40 additional depositions, including Marchionne's. The U.S. Justice Department sued Fiat Chrysler in May 2017, accusing it of illegally using software to bypass emission controls in 104,000 diesel vehicles sold since 2014. Fiat Chrysler has held numerous rounds of settlement talks with the Justice Department and California Air Resources Board to settle the civil suit, including talks as recently as earlier this month. It faces a separate criminal probe into the matter.
