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:

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

Trump tells Detroit 3 CEOs he wants more US jobs, calls environmentalists 'out of control'

As expected, President Donald J. Trump met with top executives from FCA, Ford, and General Motors this morning as part of a larger push to generate jobs in America. "I want new plants to be built here for cars sold here!", Trump said in a tweet ahead of the meeting. Not everything said in the meeting was made public, but the President later tweeted that he had a "Great meeting with automobile industry leaders." FCA CEO Sergio Marchionne, Ford chief Mark Fields, and GM's Mary Barra all echoed the positive vibes after the meeting. In a statement, Barra called the discussion "very constructive and wide-ranging," adding that it focused on "policies that support a strong and competitive economy and auto industry," and "that supports the environment and safety." That's noteworthy, because Trump is reported to have said "I am to a large extent an environmentalist. I believe in it, but it's out of control." Fields, speaking to reporters after the meeting, said, "We're excited about working together with the president and his administration on tax policies, on regulation and on trade to really create a renaissance in American manufacturing." The Ford CEO was specifically talking about Trump's withdraw from the Trans-Pacific Partnership. "We've repeatedly said that the mother of all trade barriers is currency manipulation, and TPP failed in meaningfully dealing with that, and we appreciate the president's courage to walk away from a bad trade deal," he said. Marchionne focused on American manufacturing in his statement after the meeting. "I appreciate the President's focus on making the US a great place to do business. We look forward to working with President Trump and members of Congress to strengthen American manufacturing." Perhaps equally as interesting as what was said and who was invited are what wasn't said and who wasn't invited. Trump has been very vocal about his distaste for US automakers' plants in Mexico, but no mention was made of the North American Free Trade Agreement by Trump or any of the Detroit CEOs after the meeting. We also have to wonder if Trump plans to meet with representatives from German, Japanese, and Korean automakers that have made massive investments into American plants and produce a large number of cars in this country.
