Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

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.

How fracking is causing Chrysler minivans to sit on Detroit's riverfront

It's fascinating the way that one change to a complex system can have all sorts of unintended consequences. For instance, there are hundreds of new Chrysler Town and County and Dodge Grand Caravan minivans built in Windsor, Ontario, sitting in lots on the Detroit waterfront because of the energy boom in the Bakken oil field in the northern US and parts of Canada.
The huge amount of crude oil coming from these sites mostly use freight trains for transport, and that supply boom has resulted in a shortage of railcars to carry other goods. According to The Windsor Star, North American crude oil transport by train has gone from 9,500 carloads in 2008 to 434,032 carloads in 2013. Making matters worse, some North American rail infrastructure is still damaged because of this year's harsh winter, and that's slowing things down even further.
Chrysler admits to The Star that it has had some delivery delays due to the freight train shortage. In the meantime, it's using more trucks to deliver its vehicles. Trucking is a far less economical solution, partially because a train can carry so many more units at one time, but alternatives are slim. The Windsor plant alone has a deal for 33 trucks to distribute the minivans around Canada and the Midwestern US.
