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:

Stormtrooper Dodge Charger Episode IV: A New Soap

We spent a day with a Dodge Charger that looks like a Stormtrooper helmet and made a few videos. In this one, the Charger meets the car wash. May the force be with the dryer. Read about the car and watch the rest of the videos here.

2016 Dodge Viper ACR First Drive [w/video]

The Dodge Viper is not a comfortable car. Livable, yes. The interior is covered in fine materials. But you still climb over a hot door sill to enter the tiny cabin. And the frequency range of the engine's noises seem specifically designed to cause headaches. What happens, then, if you remove all pretense of civility from a Viper and add equipment solely aimed at improving lap times? You would have the 2016 Dodge Viper ACR. In terms of achieving its purpose, this car is a absolute success. In many ways it's also the most honest Viper of the current generation. Prices start at $121,990 (including $2,100 gas-guzzler tax and $1,995 destination), or $32,900 more than the least expensive Viper. In ACR trim, the Viper loses the under-carpet padding, 9 of 12 speakers plus amplifier, carpet and trim from the cargo area, and sound deadening in front of the rear wheel wells. The parts of the interior still covered add healthy amounts of Alcantara or optional carbon fiber. That weight loss is compensated by the addition of go-fast bits like the giant rear wing (or the larger "x-wing" on the Extreme Aero Package), 10-way adjustable Bilstein Motorsports shocks, Brembo carbon-ceramic brakes, a rear diffuser, and a front splitter. Total claimed curb weight is 3,392 pounds in Aero trim (standard ACR trim is 18 pounds lighter), which is within a few stone of the rest of the Viper lineup. The diffuser strakes and leading edge of the splitter are removable, made to be replaced after rubbing on track tarmac and make street driving slightly more practical. Not that you'd want to drive the ACR on the street, with the lack of noise insulation and spring rates twice as stiff as the Viper TA, but it is street-legal. Dodge claims the DOT-approved Kumho Ecsta V720 tires on the ACR allow faster lap times than some race compound tires. Our test was limited to on-track shenanigans at Virginia International Raceway. Which is fitting because we wouldn't have anything good to say about driving the car on the street. The ACR is, essentially, a race car sold in the showroom, although with the Viper's 1 of 1 customization program, your custom build can include as many creature comforts as you like. Lined up in pit lane at VIR, the Viper ACRs for our evaluation blur the air with heat shimmer. All of the test cars have air conditioning, but that shuts off at full throttle with a six-second reset.
