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 nets quickest lap in police car test

We wouldn't advocate trying to outrun the police, no matter what you're driving and no matter what they are. But if you see a Dodge Charger bearing down on you with blue lights flashing in your rearview mirror, you'd better think twice before attempting to flee, because the Charger Pursuit has once again emerged as the fastest police cruiser out there.
In the latest Police Vehicle Evaluation held by the Michigan State Police at Grattan Raceway, Dodge says its new Charger Pursuit AWD posted a lap time of 1:33.85. That's quicker than any of the other law enforcement vehicles present, but also makes it the quickest all-wheel-drive cruiser available to law-enforcement officials. That may not make it the quickest of all time, but that honor belongs to the rear-drive Dodge Charger Pursuit, which cuts a fraction of a second off its AWD counterpart's time with a 1:33.70. But in regions where the extra traction could come in handy, that's as negligible a difference as we've ever seen.
Of course, the annual PVE sessions held by the Michigan State Police take in to account a wide variety of performance tests, including top speed, acceleration, braking, handling, fuel economy and ergonomics. The MSP has yet to reveal its full findings from its 2014 model year tests, but we'll be sure to bring them to you when they are published.

Fiat Chrysler expands Takata airbag recall to 3.3M vehicles

Fiat Chrysler Automobiles is expanding its recall of vehicles equipped with Takata airbags, moving beyond Florida, Hawaii, Puerto Rico and the US Virgin Islands to the greater US, as well as Mexico, Canada and beyond. The affected vehicles, some 3.3 million in total, were built between 2004 and 2007, with many models, including the Dodge Ram 1500, 2500 and 3500, Durango and the Chrysler 300, having been affected by Chrysler's previous recall. Despite the somewhat alarming nature that comes with a recall of this many vehicles, it seems that Chrysler is moving more out of an abundance of caution (and federal pressure) than anything else, saying: "Neither FCA US, nor Takata Corporation, the supplier, has identified a defect in this population of inflators. These components also are distinct from Takata inflators cited in fatalities involving other auto makers. More than 1,000 laboratory tests have been performed on these components. All deployed as intended, but FCA US continues to study the suspect inflators, which are not used in the Company's current production vehicles." Owners of affected vehicles will be notified and asked to report to dealers for a free replacement driver's side airbag. Scroll down for the official press release from FCA. Statement: Global Air-Bag Inflator Replacement December 19, 2014 , Auburn Hills, Mich. - FCA US LLC will replace driver's-side air-bag inflators in an estimated 3.3 million older-model vehicles worldwide, in an expansion of an ongoing regional field action. Neither FCA US, nor Takata Corporation, the supplier, has identified a defect in this population of inflators. These components also are distinct from Takata inflators cited in fatalities involving other auto makers. More than 1,000 laboratory tests have been performed on these components. All deployed as intended, but FCA US continues to study the suspect inflators, which are not used in the Company's current production vehicles. Outside of Florida, one of the areas covered by the original action, no FCA US vehicle has been linked to an air-bag deployment of the type that has raised public concern. Nevertheless, the Company is replacing the Takata components tied to that concern. FCA US is aware of one related injury involving one of its vehicles, an older-model sedan. It occurred in a southern Florida region marked by persistent, high, absolute humidity – a condition believed to be a contributing factor in the air-bag deployments under investigation.
