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.

Chrysler Recalling 870,000 SUVs For Brake Defect

Chrysler is recalling nearly 870,000 SUVs because corrosion may make the vehicles' brakes harder to use. Jeep Grand Cherokee and Dodge Durango SUVs from the 2011 through 2014 model years are involved. Chrysler says crimp joints in the brake boosters can corrode if they're exposed to water. If the water freezes, the boosters won't aid braking as they usually do. Chrysler began investigating after some customers said their brakes felt too firm when pressed down. The company knows of one accident, but no injuries, due to the defect. Dealers will install a shield to protect the boosters for free and replace boosters that aren't working properly. Chrysler has since changed the design to make the boosters more corrosion resistant. Chrysler will notify owners of the recall, which involves 867,795 vehicles.

2015 Dodge Challenger SRT 392

I've just started reading the third installment in a planned five-book biography of Lyndon Baines Johnson, Master of the Senate, written by the incomparable Robert Caro. Conveniently, a recent trip to drive the BMW X6 M and 228i Convertible was to be staged in Austin, TX, within easy driving distance of LBJ's birthplace, Johnson City. And yes, the city is named for his family. Having completed my duties with the Bimmers, I borrowed the spangled 2015 Dodge Challenger SRT 392 you see above, to squire me around the Texas capitol for a weekend, and as a lift out to the Hill Country homestead of our 36th President. Johnson City isn't exactly a road trip mecca, but there's a pretty good brewery, a museum, the reconstructed LBJ house to take snapshots of, and it's a nice drive to get out there if you've got a 485-horsepower muscle car at your disposal. Driving Notes With the heroic Hellcat, this 392 and the R/T Scat Pack (that Brandon Turkus reviewed recently), there are more SRT-treated Challengers to choose from than ever before. There are 707 obvious reasons that the Hellkitty is the top dog (as it were), but there are important difference between this 392 and the Scat Pack, too. Both cars make use of the 6.4-liter Hemi V8 putting out 485 horsepower and 475 pound-feet of torque, but the 392 also gets an adaptive suspension, six-piston Brembo brake calipers (instead of four-piston), wider tires, leather and Alcantara seats, a heated steering wheel, a louder stereo and HID headlights. When LBJ was campaigning for his seat in the House of Representatives, he would've loved to have something as potent as this monster of a V8 under the hood of his canvassing car. The 6.4L snorts with authority before it sends the big coupe forward to just about any speed I'd ask of it, and with a quickness. Johnson was known for haranguing drivers to step on it, when all that stood between himself and a few more votes was the ability to fit one more stump speech into the day. The 392 feels as though it could cover a quarter of the state of Texas in a morning if you throttle down deep enough (faster even than the Johnson City Windmill, I'd guess). Though there's a six-speed manual available, I'm actually quite fond of the eight-speed automatic in the 392. The two-pedal setup better suits the fast-cruiser attitude of the car, and it never served up any poorly conceived shift logic when I left it in D. Of course, the roads are better now than they were in the 1930s and 40s, too.
