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.

Chrysler, Nissan minivans earn 'dire' crash test results, says IIHS [w/video]

First introduced in 2012, the Insurance Institute for Highway Safety's small-overlap frontal crash test has become the bane of many auto engineers' existence. It's a particularly steep design challenge because it forces just 25 percent of a vehicle's front end to take the brunt of a 40-mile-per-hour impact. The newly released results of four family-minded minivans underscore just how difficult the crash test is: only one scored an Acceptable rating, and the other three did very poorly. The 2008-2015 Chrysler Town & Country and Dodge Grand Caravan, plus the 2011-2015 Nissan Quest, all received Poor ratings in the test, the IIHS' lowest possible score. The three of them showed significant crash intrusion into the driver's area. The dummy in the Nissan actually had to be cut out of the vehicle, with an IIHS spokesperson remarking, "the structure collapsed like a house of cards." In the Fiat Chrysler Automobile vans, the steering wheels moved out of the way, making the airbag less effective and letting the driver's head hit the dashboard. While it was not actually crashed, the agency is also giving the 2009-12 Volkswagen Routan a Poor score because it shares a structure with the FCA models. The newly released results of four minivans underscore just how difficult the small-offset crash test is. The refreshed 2015 Toyota Sienna (shown), conversely, earned an Acceptable rating and is also a Top Safety Pick+ because of its optional forward collision warning and automatic braking system. While the crash test dummy moved around during the impact more than the agency would have liked, sensors showed a low risk of injuries. The IIHS tested the Honda Odyssey last year, and it earned a Good overall score, the agency's best ranking. It's also a Top Safety Pick+ vehicle. The only member of the minivan segment left to test is the latest Kia Sedona, and the Institute is reportedly waiting a little longer for Kia to make changes to improve the model's performance. When reached for comment, Nissan spokesperson Steve Yaeger provided Autoblog with the following statement: "Nissan is committed to vehicle safety and believes that consumers should have information about crash protection so they can make educated buying decisions. Nissan is proud of the 2014 Quest's "good" rating in the IIHS front moderate overlap and side impact tests as well as a "good" head restraint rating.

Dodge Charger Hellcat and Tesla Model S P85D in Motor Trend Head 2 Head battle

One has James Bond Mode, Insane Mode, Creep Mode, and, yes, Insane Creep Mode. The other has 707 horsepower and is a heck of a lot cheaper. But which one is the bigger American badass? We figure most people already have strong opinions on the Dodge Charger Hellcat and Tesla Model S P85D, and they aren't likely to be swayed too far in the opposite direction by another person's viewpoint. Still, we think you'll enjoy watching the video above. In it, Autoblog friend and Motor Trend "Head 2 Head" host Jonny Lieberman summons smoke, shares smiles, and spouts spiels about both cars, finally finding one just slightly more badass than the other. Which ridiculously ludicrous American sedan takes top honors? Watch above to find out.
