Dodge engineers trying to shoehorn Pentastar into Dart?

The fact that the Dart's launch has been a pretty dismal affair isn't what we'd call secret. Judging by its mounting inventories and poor critical reception, Dodge's successor to its unloved Caliber has struggled since it hit the market. And while both of those are difficult problems to address, at least their cause is well known - the powertrain.
Even Fiat-Chrysler CEO Sergio Marchionne has acknowledged that the powertrain options in the Dart are substandard, admitting at January's Detroit Auto Show that the powertrains are "less than ideal." Leading with the 1.4-liter turbocharged four-cylinder found in the Fiat 500 Abarth left a bad taste in the mouths of consumers thanks to the laggy engine and dead throttle response (to say nothing of the manual and dual-clutch gearboxes that needed more refinement). The addition of the 184-horsepower 2.4-liter Tigershark in the Dart GT has helped matters some, but apparently Auburn Hills doesn't think it's quite enough.
If rumors are to be believed - get that salt ready - a possible solution may be in the works. A report from Allpar is claiming that Dodge is considering fitting a Pentastar V6 into the Dart's engine bay. As the Mopar-obsessed website points out, the critically acclaimed Pentastar is available in three different sizes - 3.0 liters, 3.2 liters and the original 3.6 liters. We don't get the 3.0 here in the US, but the 3.2 can be found in the new Jeep Cherokee and the 3.6 has been seemingly fitted to every model Chrysler can shoehorn it into.

A look at the Dodge Demon's drag settings, modes, and go-fast tech

In the same video that gave us a peek at the 2018 Dodge Challenger SRT Demon's performance stats, there's a serious dump of info on the tech and tools that will likely help this muscle coupe slaughter drag strips. Dodge has outlined a few of them for us and we're using the power of inference to figure out the rest. Here's what we've gathered. A lot of these hints come from the Demon's version of Performance Pages, the infotainment screens that show what SRT models are doing and let the driver change the powertrain and chassis setup. There are a lot of Demon-only features, including line lock, a quick cooldown mode for the supercharged engine, and data recording. And of course there are pages to show a digital time slip with acceleration and braking figures, a g-load plot, and lots of gauges to track temps and levels. The engine output is shown in the video on a special Dyno page. It tracks horsepower and torque over time on the upper graph, and engine rpm and shift points on the lower graph. And we think it's still hiding something. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Any good drag car has a line lock, allowing the driver to lock the front brakes and leave the rears free to do a nice tire-warming (or tire-shredding, depending on length) burnout. Ford has it on the Mustang, Chevy puts it on the ZL1, and now Dodge is adding it to the Demon. It should help get the giant Nitto tires up to temp for a drag run. And once the tires are warm, there's launch control, just like on the SRT Hellcat, with selectable rpm to dial things in for the conditions. The Demon also has a shift light in the cluster, and the driver can set a shift point individually for each gear. After each drag run, you can activate Quick Cooldown, which Dodge says uses the first production application of After-Run Chiller – it runs the cooling fan and intercooler coolant pump with the engine off until the coolant reaches its target temp. It's shown in one of the slides above. The checklist on the left side of that page suggests it requires a set of conditions be met to work: engine off, hood open, and sufficient battery level. This further reinforces our theory that the supercharger is going to make big boost, beyond the Hellcat's 11.6 psi. And while you're waiting for the supercharger to cool off for another run, you can review the performance data the car records.

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.
