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.

2019 Dodge Charger SRT Hellcat gets some Demon goodies

The 2019 Dodge Charger SRT Hellcat has been revealed, along with details on the rest of the range. Though the new Charger doesn't look a whole lot different, there are a number of special upgrades, especially for the Hellcat. The least interesting changes are on the outside. The Hellcat and the R/T Scat Pack get a new grille with twin air intakes next to the headlights. The regular RT and GT get some sportier additions such as a hood scoop, rear spoiler, and some other revised body work. The Hellcat also now gets a matte black hood option, as seen on the gray car above. Under the skin are more interesting upgrades. The Hellcat raids the Demon parts bin for its "After-Run Chiller" that continues providing cooling to the intercooler after the engine has been shut off. This way you'll still get cool air for another run when you come back and fire it back up. The Charger Hellcat also gets the Demon's fancy "Torque Reserve" system to start generating boost right at launch. Both the Hellcat and the R/T Scat Pack also come with line lock for big smoky burnouts and "Launch Assist" for minimizing wheel hop and maximizing grip. Both cars have the same power and torque as last year's iterations, though. Dodge hasn't left out its lower-rung Charger models, either. The R/T now gets standard performance suspension and shift paddles, along with a 2.62 rear axle. The GT model is now available in rear-wheel drive, and it's being marketed as more of a performance-oriented trim for the V6. As such, it also gets the performance suspension as standard, a 3.07 rear end and shift paddles. The SXT rounds out the base of the lineup and now has an all-wheel-drive option. Output remains the same with these vehicles, and the GT continues to make 300 horsepower and 264 pound-feet of torque while the SXT makes 292 horsepower and 260 pound-feet. 2019 Dodge Chargers will start showing up on dealer lots in the third quarter of this year. If you're really eager to get one, dealers will be able to start ordering them by the end of June. Pricing hasn't been announced yet for the big sedan. Related Video:

Chrysler extends fuel tank warranties on LX cars, NHTSA ends probe

The National Highway Traffic Safety Administration has ended its investigation of 153,817, 5.7-liter and 6.1-liter Hemi V8-powered 2006 Chrysler 300, Dodge Charger and Dodge Magnum models after reports of stalling. Chrysler has responded by granting a lifetime warranty on the fuel tanks for these vehicles.
NHTSA received 299 reports of engines stalling while the models were stopped or driving at low speeds, and began an investigation. The government agency found that the control valve shutoff float in the V8s' 19-gallon fuel tank could malfunction if the fuel had too high of an ethanol content. In many cases, the valve would break in the open position, allowing the tank to be overfilled, which would then cause the cars to stall. However, there were no accidents reported, and the vehicles could be restarted immediately.
There will not be a recall on these vehicles because, "the condition represents a low risk to motor vehicle safety and is adequately addressed by Chrysler's extended warranty," NHTSA said to The Detroit News.
