The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues. Hardware: 35 percent lower rate front springs/28 percent lower rate rear springs 75 percent lower rate hollow front sway bar/44 percent lower rate rear sway bar Drag-tuned Bilstein Adaptive Damping Shocks Software: Rear = F/F and Front = F/S F/F – F/S maintained @ wide open throttle (WOT) F/F – F/F < WOT Traction control disabled/ESC maintained Result: 13.5=575@500 Related Video: This content is hosted by a third party.

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:

China's Great Wall confirms its interest — in Jeep, or all of FCA

HONG KONG/SHANGHAI — Chinese automaker Great Wall Motor reiterated its interest in Fiat Chrysler Automobiles NV on Tuesday, but said it had not held talks or signed a deal with executives at the Italian-American automaker. China's largest sport utility vehicle manufacturer made a direct overture to Fiat Chrysler on Monday, with an official saying the company was interested in all or part of FCA, owner of the Jeep and Ram truck brands. Automotive News first reported the news, quoting Great Wall Motor President Wang Fengying as saying she planned to contact FCA to discuss acquiring the Jeep brand specifically. Those comments sent FCA shares higher but also raised questions over the ability of China's seventh-largest automaker by sales to buy larger Western rival FCA, or even Jeep, which some analysts value at as much as one-and-a-half times FCA. Great Wall sought to dampen speculation on Tuesday. It confirmed it had studied Fiat Chrysler, but said there was "no concrete progress so far" and "substantial uncertainty" over whether it would eventually bid. "The company has not built any relationship with the directors of FCA nor has the company entered into any discussion or signed any agreements with any officer of FCA so far," the company said in an English-language stock exchange filing. It did not give further detail. Fiat Chrysler stock dipped on the statement on Tuesday. Great Wall said trading in its Shanghai-listed shares would resume on Wednesday after having been suspended. Fiat Chrysler declined to comment on Great Wall's statement. On Monday, it said it had not been approached and was fully committed to implementing its current business plan. FLUSHING OUT RIVALS? Great Wall Motor, which was early to spot China's love of SUVs, had revenue of $14.8 billion last year and sold 1.07 million vehicles - but that compares with FCA's 2016 revenue of 111 billion euros ($130.6 billion). Analysts said Great Wall would need to raise both debt and equity to complete any deal, meaning its chairman Wei Jianjun could lose majority control. One possible scenario, according to analysts at Jefferies, would see Wei keeping a roughly 30 percent stake, while Great Wall would raise $10-$14 billion in debt and $10 billion in equity - hefty for a group currently worth just $16 billion. Ultimately, politics could be the clincher.
