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:

Dodge Charger Pursuit takes Tesla interior approach

A police car's computer is just as integral to its duties as a set of lights and sirens. The popular approach for these systems is to grab something like a Panasonic Toughbook laptop, add a big, bulky tray to hold it, and use this inelegant setup for running plates and doing all the other things a cop needs to do while on the road. The downside, besides simple aesthetics, is that this arrangement robs the officer's shotgun-riding partner from legroom. Dodge, though, has come up with a far more elegant and functional solution. Taking a page out of Tesla and Volvo's book, Dodge has replaced the five-inch UConnect display and laptop mount in the Charger Pursuit police car with an enormous 12.1-inch, portrait-format touchscreen display. Called, UConnect 12.1, the new system doesn't do away with the old fashioned computer outright. Instead it moves the bulky unit to the trunk, where it can connect to the display via an ethernet cable. This is good for multiple reasons. First, there are no pricey installation or upfitting charges, like there are for most laptop carriages. Secondly, the plug-and-play nature of the new UConnect system won't require the department to buy new laptops. And third, there's no need to retrain officers, since the only thing that's really changing is the input. While the Charger Pursuit will continue to offer redundant audio and HVAC controls, the 12.1-inch display can, at the press of a "button" split to display Fiat Chrysler's familiar 8.4-inch display. Make one more tap on the screen, and the police-issue laptop can be managed through the full touchscreen. The touchscreen will also display a menu bar at the top of the page, which can easily be edited by officers. All it takes is a simple drag and drop from the application menu to the top of the display. According to Dodge, the touchscreen will even play nice when its operator is wearing gloves. "As America's high-performance police vehicle, Dodge Charger Pursuit is going big for 2016, offering a massive, Uconnect touchscreen system that streamlines a law enforcement officer's computer system with our easy-to-use Uconnect system – on an all-new laptop-sized 12.1-inch touchscreen display," said Tim Kuniskis, Dodge and SRT's president and CEO.

Chrysler Recalls Over 566,000 Trucks, SUVs

Fiat Chrysler is recalling more than 566,000 trucks and SUVs in two recalls for malfunctioning fuel heaters that can cause fires and a software glitch can disable the electronic stability control. The recalls bring the newly merged company's total for the year to 6.4 million vehicles worldwide and 5.1 million in the U.S. as it continues to struggle with reliability problems. It was not immediately clear whether those totals were annual records. On Tuesday, its longtime quality chief abruptly left after Fiat Chrysler performed poorly in Consumer Reports magazine's annual reliability rankings. The largest of two recalls announced Wednesday covers almost 382,000 Ram 2500 and 3500 pickups and Ram 4500 and 5500 chassis cabs from 2010 through 2014. In trucks with 6.7-Liter Cummins diesel engines, corrosion on a fuel heater terminal could cause overheating, fuel leaks and fires. Chrysler is not aware of any fires or injuries. Owners could be warned by an odor of diesel fuel. Customers will be notified by letters starting in December. Dealers will install upgraded terminals and fuel heater housings could be replaced. The second recall covers more than 184,000 Jeep Grand Cherokee and Dodge Durango SUVs from 2014. A debris cover over a circuit board in the steering column control module can disrupt communications and disable the stability control. The problem was discovered when dealers started getting reports from customers that electronic stability control warning lights were coming on. Fiat Chrysler says it knows of no crashes or injuries caused by the problem. Technicians will upgrade software to fix the SUVs, and customers will be notified in December. Fiat Chrysler has issued 33 global recalls and 27 in the U.S. so far this year. Doug Betts, its longtime quality chief, left the company to pursue other options after Consumer Reports' survey-based rankings this year showed four FiatChrysler brands at the bottom of its list. Dodge, Ram, Jeep and Fiat performed worst of 28 brands ranked by the magazine. Company spokesman Eric Mayne said Fiat Chrysler's recalls average fewer than 200,000 vehicles each, below the industry average of 301,000. That means the company is responding quickly to problems, he said, adding that eight of its 27 U.S. recalls were announced before the company received any consumer complaints. Chrysler is not alone with a high number of recalls so far this year.
