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:

Chrysler recalling 31k SUVs and vans

Chrysler is issuing recalls covering roughly 31,700 vehicles worldwide due to two separate problems. In both cases the company believes that most of the affected vehicles are either still on, or in transit to, dealer lots.
One recall covers roughly 10,700 Dodge Durango, Jeep Cherokee, Grand Cherokee and Grand Cherokee SRT models from the 2014 model year built between January 16 and April 17, 2014. The SUVs need a software update for the cruise control. It's possible that when the cruise is on and the driver presses on the throttle, the acceleration could last a second after the pedal is released or two seconds for the SRT. Afterward, they return to the speed originally set by the driver.
Chrysler says it isn't aware of any accidents, injuries or even reported incidents of this happening in the real world. Also, in all cases, if the driver presses on the brake, the cruise shuts off. The automaker believes that there are about 6,100 affected SUVs in the US, 950 in Canada, 425 in Mexico and 3,200 outside of North America. The software upgrade will be ready shortly, the company says.

Nearly 700,000 Jeep Grand Cherokee and Dodge Durango SUVs recalled

WASHINGTON — Fiat Chrysler Automobiles said on Thursday it will recall nearly 700,000 sport utility vehicles worldwide because a faulty electrical connection could prevent engine starts or contribute to a stall. The recall, covering 2011 through 2013 model year Dodge Durango and Jeep Grand Cherokee SUVs, will address silicon deposits on the contact points of fuel pump relays that may interrupt electrical current, Fiat Chrysler said in a statement. It said it is unaware of any injuries or accidents related to the faulty vehicles. The Italian-American automaker had previously recalled most of the same SUVs in 2014 and 2015 for issues with their fuel pump relays. The company, which last month announced it planned to merge with Peugeot owner PSA, said it would notify owners at a later date when they will be able to schedule repairs at dealerships. The recall includes around 528,500 vehicles in the United States, 34,700 in Canada, 18,100 in Mexico and 116,500 outside North America, it said.
