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:

Detroit automakers observing 8:46 of silence to mark Juneteenth

GM Executive Vice President of Global Manufacturing Gerald Johnson, right, talks with employees at the Fairfax Assembly & Stamping Plant in Kansas City, Kansas. (file photo - GM)     All three Detroit automakers are observing Juneteenth, a day commemorating the end of slavery, on Friday by observing 8 minutes and 46 seconds of silence, among other companywide efforts to advance the causes of social and racial justice and equality. Juneteenth marks the date, June 19, in 1865 when Union soldiers, led by Maj. Gen. Gordon Granger, arrived at Galveston, Texas, and announced the Civil War had ended and enslaved African Americans were to be freed. President Abraham Lincoln had officially ended slavery more than two years prior via the Emancipation Proclamation, but Union forces didn't reach Texas until that time, so there was virtually no enforcement. The 8:46 timestamp is significant because it was the length of time that a police officer in Minneapolis knelt on the neck of George Floyd during an arrest, ultimately killing him and sparking waves of protests across the U.S. and overseas. Autoblog asked automakers about their plans to mark Juneteenth, what they were doing to advance the cause of social justice for Black people, and how many African Americans they employ in both blue- and white-collar jobs. We heard back from GM, Ford, Fiat Chrysler and Honda but not from Nissan and Toyota. General Motors GM’s U.S. workforce is 17.2% Black and 69.2% white, according to its most recent corporate Diversity and Inclusion Report. GM's total global employment is 173,000, and it says women and minorities represent 40% of its team of corporate officers. For reference, the Census Bureau says African Americans make up 13.4% of the U.S. population of roughly 328 million people. White people constitute 76.5%. As previously reported, GM planned to pause production at its factories on each shift today and observe silence for 8 minutes and 46 seconds. The company will also have a digital countdown clock atop the GM's headquarters in Detroit for the moment of silence. Additionally, Chairman and CEO Mary Barra has said she will lead a new Inclusion Advisory Board made up of people from within and outside GM to suggest areas for change and hold the company to its commitments to fight injustice and racial inequality.

Lee Iacocca's very first Dodge Viper RT/10 nets $285,500 at auction

The first 1992 Dodge Viper RT/10 to roll down the assembly line, which was snapped up by Chrysler chief Lee Iacocca, yesterday hammered at the Bonhams auction in Arizona for $285,500, more than double the pre-sale estimate. According to a history of the car published by the auction house, Iacocca, in his introduction of the Viper to the press, pointed to the car on stage and said, "This one right here is mine." That historic Viper, with serial number 001, has never been available on the open market, as Iacocca kept the car from new until he passed away last year. The car has been driven just 6,200 miles and was being sold by his estate. Other Lee Iacocca cars offered at the same sale fared less well. A 1986 Chrysler LeBaron Town & Country convertible — the ultimate expression of Iacocca's company-saving K-cars — with 20,500 miles on it sold for $19,040. That's less than the $20,000 to $25,000 the auction house had estimated the car would bring. A third car from the former auto executive's estate was a customized 2009 Ford Mustang. The pony car was one of a limited run of 45 Iacocca-branded custom Mustangs, which were reworked by Metalcrafters and sold by Galpin Ford in Los Angeles. The Iacocca Mustang, never titled and with 220 miles on it, hammered for $49,280.
