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:

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

Killing the Dart and 200 might lower FCA's fuel economy burden

Killing the Dodge Dart and Chrysler 200 could allow FCA US to take advantage of an intriguing quirk in the next decade's fuel economy regulations. By increasing its ratio of trucks versus cars, the automaker might not need to worry so much about hitting the more stringent efficiency rules. At first thought, it might seem harder for an automaker with a ton of trucks to meet the government's mandated 54.5 mile per gallon corporate average fuel economy for 2025. However, every company doesn't need to hit that lofty figure, according to The Detroit Free Press. The exact target varies by the product mix between trucks and cars. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target," Brandon Schoettle, Project Manager Sustainable Worldwide Transportation at the University of Michigan Transportation Research Institute, told Autoblog. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target." FCA US' current product blend has 80 percent pickups and CUVs, which means the company stands to benefit from a lower fuel economy target. It might not seem entirely fair environmentally, but this is a great move from a business perspective. The new CAFE rules aren't set in stone, according to The Detroit Free Press, but potentially taking advantage of the regulation is just one more reason to cut the Dart and 200. Modern crossovers also aren't gas guzzlers like older SUVs, which could make it easier to hit the fuel economy target. "Utilities offer practicality and versatility that cars do not, and now, built on car architectures, they do not penalize consumers on fuel economy as they once did," AutoTrader Senior Analyst Michelle Krebs told Autoblog. Schoettle warns that FCA is still making a gamble by killing the small sedans. "Depending on the previous sales volumes and how much these vehicles might have exceeded their specific CAFE targets, it's possible that these cars helped earn CAFE credits for FCA that they could bank for future use," he said.
