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 Dart pushed toward the grave with simplified lineup

FCA announced a while back that the Dodge Dart and its Chrysler 200 half-sibling are on the way out due to lack of interest. The 2016 model year will be the Dart's last, and Dodge has just reconfigured the lineup mid-year to lower (relative) pricing and streamline ordering. Streamlined is a nice way of saying there will be fewer choices, with three models (down from five) and limited customization beyond choosing the paint color. The odd thing is that the Dart continues to offer three different engines. And while the prices of the individual models have decreased, the former SE base trim is now gone. That means an early-2016 Dart was available for as little as $17,990, while the late-2016 Dart starts at $18,990. For that sum you get the new base model, the SXT Sport, which replaces the SXT and comes with the 2.0-liter Tigershark four-cylinder (160 horsepower, 148 lb-ft of torque) and a six-speed manual; a six-speed automatic is an available option. Standard equipment includes normal entry-level car stuff, black cloth upholstery, 16-inch wheels, and grille shutters that help improve fuel economy. The SXT Sport can be dressed up with one of three different appearance packages; Chrome adds bright accents to parts including the grille and door handles, Rallye has a black grille and a touring suspension, and the Blacktop package makes pretty much everything on the exterior black and includes a sport-tuned suspension. All three packages come with bigger wheels, too. From there it's on to the new Dart Turbo, for $20,490. It comes with the 1.4-liter turbo four (160 hp, 184 lb-ft of torque) and comes exclusively with a six-speed manual transmission. This is supposed to be the model for enthusiasts, which is how Dodge is selling the switch to manual-only. Ditching the disliked dual-clutch automatic that was previously offered with this engine doesn't hurt. This engine was also used in the former Aero model, as it's the most fuel-efficient in the lineup. The Turbo gets the Rallye appearance stuff and a different hood. At the top is the Dart GT Sport, starting at $21,900. It has the 184-hp, 2.4-liter Tigershark four-cylinder and a choice of six-speed manual or automatic transmission. This is the one with features, including a power driver's seat, the 8.4-inch Uconnect infotainment unit, digital reconfigurable gauges, dual-zone auto climate, keyless start, and a rearview camera. The latter-part-of-2016 Dart will be available in eight colors.

Dodge Viper ACR reportedly green lit [w/video]

The Dodge Viper might be getting a little more venomous in the near future thanks to a return of the performance-honed ACR trim. According to an anonymous source leaking the info to Allpar, the version would go into production in July as a 2016 model year vehicle. FCA US showed a concept for a future ACR (pictured above) at the 2014 SEMA Show that sported carbon fiber parts for the front splitter and dive planes, plus a picnic-table-sized rear wing. The body also received ducts at the rear to shoot cool air to the differential. A set of 15.4-inch carbon-ceramic brake rotors also brought things to a halt in a hurry. The company promised all the aero pieces were sculpted in the wind tunnel to give the coupe even more downforce. To shed weight, engineers chucked the radio, speakers, carpet and sound deadening out of the interior, and they replaced many bits with even more carbon fiber. All of the tweaks are necessary because the ACR moniker carries serious cachet for the Viper at the track, especially at the Nurburgring. One reportedly did a 7:22 lap around the 'Ring in 2008, and another improved that further to 7:12 in 2011. Autoblog reached out to FCA US for comment about the possibility for the hotter Viper, but the company wasn't willing to comment about any possible, future projects. Related Video:
