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 bringing revamped Challenger, Charger to Big Apple

The 2014 New York Auto Show will be a big one for Dodge, as the brand has announced that refreshed versions of the 2015 Challenger and 2015 Charger will debut at the show. This is a particularly big deal for the two-door Challenger which, visually, has remained unchanged since is burst back onto the scene in 2008 and helped reignite the muscle car wars.
As a sort of hint, this announcement was accompanied by the picture you see above - the Super Bee logo in the Challenger's new instrument cluster. According to Dodge, the New York debut of a new "powertrain combination" - possibly with the high-output Hellcat V8 - will leave enthusiasts "abuzz."
As for the Charger, Dodge is promising a full redesign that should be a significant departure from the blunt, angry looks of the current model. At this point, there's no indication that the Challenger's new powertrain could be fitted to the Charger, although considering how mechanically similar these two vehicles have been, it doesn't seem outside the realm of possibility.

Dodge Durango SRT vs. Jeep Grand Cherokee SRT | Which should you buy?

Choice is a good thing. And when it comes to high-performance sport utility vehicles, there are more choices today than ever before to tantalize buyers into showrooms. And why not? Americans love SUVs, and, while there's a stronger push to go green now than ever before in the history of internal combustion, there's still a large contingent of buyers who firmly believe in choosing the biggest, baddest, most powerful powerplant. For those buyers, the Dodge Durango SRT and Jeep Grand Cherokee SRT are two of the most potent options. But which one should you buy? They both deliver 475 horsepower and 470 pound-feet of torque to all four wheels through an eight-speed automatic transmission. They both do 0-60 in around 4.4 seconds, and both boast top speed numbers that will handily land you in jail if written on a speeding ticket. Choosing between the two, then, is a bit more nuanced than which is faster. That said, the Jeep is probably a bit quicker at the track than the Dodge. We'd wager than the Grand Cherokee SRT's 5,104-pound curb weight (versus 5,510 for the Durango SRT) and 114.8-inch wheelbase (versus 119.8) will pay small dividends in acceleration, cornering, and braking performance. So, if that's the only category by which you believe these SRT-fettled SUVs should be judged, choose the Jeep. View 17 Photos But let's get real here for a moment. As much fun as it is to wrangle a brutish ute 'round a racetrack – and trust us when we tell you it's a blast – the number of hi-po SUV owners who will ever show up at Bondurant in an SRT-badged 4x4 is probably in the single digits. So, when evaluating which of the two Hemi-powered vehicles is right for you, ultimate lap times are probably of little concern. If you're choosing between these two overpowered players, practicality is probably just as important as performance. And in that category, the Durango SRT comes out on top. For starters, the Dodge is a three-row SUV with six seats, whereas the Jeep is a two-row, five-passenger platform. Fold down the rear bench and there's 84.5 cubic feet of cargo area in the Durango, versus 68.7 in the Grand Cherokee. And if you tow, the Durango SRT's 8,600-pound max rating handily bests that of the Grand Cherokee SRT's 7,200-pound capacity. Ask yourself what's most important: performance or practicality. And then consider the price. The Dodge is nearly $4,000 less expensive than the Jeep.
