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:

Porsche and Dodge lead JD Power's 2020 APEAL Study

This may sound obvious, but we'll say it anyway: if an automaker delivers exactly the ownership experience that buyers are looking for and have come to expect, they are going to score well in studies designed to measure a vehicle’s appeal. ThatÂ’s why Porsche, with a score of 881, sits at the top of all vehicle brands in JD PowerÂ’s 2020 Automotive Performance, Execution and Layout (APEAL) Study, which is designed to gauge how owners feel about their vehicles on an emotional level. And it's also why Dodge's score of 872 leads all Mass-Market brands, followed closely by corporate cousin Ram. It's worth noting that Dodge — a brand primarily known these days for packing as much horsepower into its aging lineup as possible — was also atop JD Power's 2020 Initial Quality Study (IQS) rankings, making it the first domestic automaker to lead both categories in the same year. Before we continue on with the rest of the winners and losers, we'll mention that Tesla is only unofficially included in this year's study because it did not grant JD Power permission to contact owners of its vehicles in 15 states. Still, the study includes results from surveys completed in the remaining 35 states, and if Tesla had been officially included it would have led all brands with a projected score of 896. Conversely, Tesla would have sat at the very bottom in JD Power's IQS rankings. That means Tesla owners report more problems with their vehicles than owners of any other brand, yet they still love and connect with them on an emotional level. In the Premium rankings, the top five brands were Porsche, Lincoln (876), Cadillac (874), BMW (869) and Land Rover (866). At the bottom of the Premium rankings sit Acura and Audi (tied at 845). Following Dodge and Ram (871) in the Mass-Market category are GMC (857), Ford (853) and Mini (846). Interestingly, there isn't a Japanese brand anywhere in the top five of either category, with Lexus' score of 859 only good enough for eighth spot in the Premium category. The worst performers overall were Volkswagen (832), Mitsubishi (829), Chrysler (828), Toyota (825) and Jeep (822). When asked why Jeep, a brand with a massive fanbase and desirable models like the Wrangler and Gladiator, could land at the very bottom of its rankings, JD Power's Dave Sargent explained that what people love about Jeeps is not necessarily captured in this study.
