The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues.

Certain Chrysler owners eligible for buyback program

Certain car owners whose Chrysler vehicles contain dangerous defects will soon have a way to get rid of their lemons without losing money. As part of an agreement with federal regulators, Fiat Chrysler Automobiles has agreed to buy back more than 500,000 vehicles susceptible to veering out of control without warning at above market-value prices. The deal mainly covers certain models of RAM trucks, the Dodge Dakota pickup and Dodge Durango SUV. Further, owners of more than 1.5 million Jeep Liberty and Grand Cherokees at heightened risk for lethal fires are eligible to trade in their vehicles at above market value or, alternately, get a gift certificate if they prefer to have repairs made. Chrysler has "a heavy responsibility to make sure the products they make are safe for the traveling public," said Mark Rosekind, administrator of the National Highway Traffic Safety Administration. "... Here, we are sending an unambiguous signal to industry that if you skirt the laws or violate the law, or don't live up to the responsibility that consumers expect, we are going to penalize you." The buy-back and trade-in options for motorists come as part of an unprecedented penalty NHTSA slapped against Chrysler for violating federal motor-vehicle safety laws. Chrysler will pay a $105 million fine, the highest ever levied by the regulatory agency. In addition to the buy-backs, Chrysler also agreed to an independent monitor for three years. Investigators had outlined problems in the company's conduct in 23 recalls that affected more than 11 million defect vehicles. As part of a consent-order agreement, Chrysler acknowledged it did not notify vehicle owners of recalls in an effective manner and did not notify NHTSA of safety problems. Though those recalls affected millions of drivers, the buy-back and trade-in options are only for a small portion of the vehicles involved. Because Chrysler struggled to fix the problem and no repair was apparent, Rosekind said the buy-backs are reserved "for customers who didn't have a remedy." Buy-backs are for trucks and SUVs affected by three recalls that occurred in 2013 (recalls 13V-038, 13V-527 and 13V-529), that addressed a rear-axle pinion nut that could come loose and cause a loss of vehicle control. Those recalls covered 579,228 vehicles, including 2009-2012 Ram 1500, 2500, 3500, 4500 and 5500 trucks, 2009-2012 Dodge Dakotas, 2009 Chrysler Aspen and the 2009 Dodge Durango.

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.
