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:

Driving the 2019 Dodge Durango Pursuit | Bells and whistles, lights and sirens

Recently, we went to the FCA proving grounds in Chelsea, Mich., to test out the company's 2019 model-year lineup. There are a lot of cars to choose from, and only a limited time to drive them, so since we couldn't drive the Dodge Challenger SRT Hellcat Redeye (that drive is coming soon, though) naturally we gravitated to the flashiest, noisiest one: the 2019 Dodge Durango Pursuit police vehicle. This is the first time the Durango is being offered as a cop car, and there are a number of features that make it fit for service. All Durango Pursuit models feature all-wheel drive, and it's available with two different engines. The standard motor is the 3.6-liter Pentastar V6, providing 293 horsepower and 260 pound-feet of torque. The tester we got to drive, though, was equipped with the 5.7-liter hemi V8, good for 360 horsepower and 390 pound-feet of torque. It also has a load-leveling performance suspension, which really helped out when we tossed it around the handling course. It has 8.1 inches of ground clearance, which means it can get to scenes off the beaten path. As much as we loved driving it, we had the most fun just playing with the lights and sirens of the Durango Pursuit. Standing outside the vehicle, the sirens and horn are incredibly loud, enough to make bystanders jump in fright. Dodge did a good job with the sound deadening, though, and the sustained wail wasn't bothersome when chasing imaginary suspects around the test track. One feature we didn't get to test out, but important to police duty, was the special Uconnect system in the Durango Pursuit. More than just an infotainment system, the seven-inch display is equipped to integrate various law enforcement systems. Another cool detail about the car, its tri-zone climate system is ideal for K9 units, with the ability to set separate HVAC settings for the dogs in the back of the car. Check out the video above, and stay tuned for more videos to come from our time spent at FCA's Chelsea proving grounds.

This or That: 2005 Dodge Ram SRT-10 vs. 2005 Subaru WRX STI [w/poll]

Some cars, due to ultimate desirability, particular rareness, or spectacular performance/prestige eventually become collectible. It's darn near impossible to know which ones will make it into the rarefied stratosphere of collectibility – why is a late 1960s AMC AMX so affordable these days, whereas prices for late '70s Pontiac Trans Ams are soaring? – but there are some useful indicators to keep tabs on. We're not exactly experts on investing, but we do know cars. As such, we've decided to take our non-expertise on one hand, combine it in the other with our knowledge of all things automotive, wad it up, throw it out and ask for your forgiveness. Or something like that. I've challenged Senior Editor Seyth Miersma to choose a car he thinks will become a future collector's item that's not more than 10 years old, and for no more than $25,000. I've done the same, and we vigorously argued for and against each other's picks. I feel good about my choice, but I don't have the best track record in these contests (I've lost three times, won twice, but they've all been pretty close), so, while I'm not going to beg (please vote for me!), I do hope you find my argument convincing. But first, let's hear from Seyth: Miersma: Ten-years old or newer makes this challenging. At that age most vehicles feel like a plain old used car to me, few hit the "classic" button. But the Subaru WRX STI has always been a special car, and the 2005 cutoff year proves to be very attractive for the parameters of our contest. It's rare; with fewer than 5,000 STI models sold that model year. It's probably the best looking WRX STI ever sold in America; narrowly avoiding the dreadful "horse collar" front fascia. And it's got one of the more die-hard car-geek followings out there. For $25,000, you can also still find examples that have reasonable miles, are in good condition, and haven't all been molested by grown-up Initial D wannabes. With the street racers hacking up collectable examples every day, I like my odds for steep appreciation by way of conservation. I couldn't agree more. It really is difficult to predict what cars will catch the eye of collectors, and the WRX STI seems like a pretty good choice. But I think mine is even better, and I can't let him know that I'd love to park just such an STI in my very own garage. And so goes my argument: Korzeniewski: I like your choice as a driver, Seyth. I'm less convinced of its status as a sure-fire collectible.
