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 644k more Dodge Durango and Jeep Grand Cherokee SUVs over brakes

Early last month, we reported on Chrysler issuing a preemptive, proactive recall for about 25,000 units of the Jeep Grand Cherokee and Dodge Durango. The issue revolved around a brake system that wasn't causing any actual problems, but delivered an unsatisfactory brake feel, so Auburn Hills called in a good 25,000 of SUVs around the world, including 18,700 in the United States.
Now Chrysler, having apparently determined that the brake problem on its sport utes is actually much bigger than it initially realized, has drastically broadened the scope of the recall. As a result, the National Highway Traffic Safety Administration has issued a recall for precisely 655,354 examples of the Grand Cherokee and Durango, covering the 2011 through 2014 model years. In addition, Chrysler is recalling 42,380 units in Canada, 21,376 in Mexico and 159,685 overseas.
The problem which Chrysler found revolves around the brake booster, whose center shell has been found to be subject to corrosion, allowing water to get into the brake system. That water in turn could freeze, preventing the brakes from working as well as expected.

2018 Dodge Challenger SRT Hellcat Widebody First Drive | Same snarl, more bite

By now, you've read a lot about the Dodge Demon, including our driving impressions from the drag strip. You've also heard a lot about the Challenger Hellcat, which we've had the pleasure of driving at Portland International Raceway, Willow Springs, and on our home turf of Woodward Avenue, both during the Dream Cruise and for an episode of AutoblogVR. Last week, Dodge and SRT invited us out to Indianapolis to sample the Demon, as well as the Durango SRT. Sandwiched between those two launches, however, was another distillation of Dodge's retro-cool coupe, the 2018 Challenger SRT Hellcat Widebody. The Widebody shares most of the guts of the standard Charger Hellcat, but went to the same cosmetic surgeon as the Demon. The Hellcat 6.2-Liter V8 with 2.4-liter-per-rev supercharger, producing 707 horsepower and 650 pound-feet of torque, is unchanged. It comes standard with a six-speed manual transmission, but our tester had the optional eight-speed automatic with steering wheel-mounted paddle shifters. It's 3.5 inches wider (look at those fenders!) than the standard Hellcat, though, which allows it to accommodate 20-by-11-inch "Devil's Rim" wheels. It shares its front splitter with the Demon, but retains the Hellcat's rear spoiler. The Widebody also features an electronic power steering system with selectable drive modes. It just slightly outperforms the standard Hellcat, as well, with better cornering grip, improved acceleration, and better braking (even though it shares the same Brembo brake package as the standard Hellcat). Dodge claims that the Widebody does the quarter-mile 0.3 seconds quicker, dropping it just out of the 11s to 10.9 seconds. 0-60 miles per hour drops from 3.5 to 3.4 seconds. Lateral grip increases by 0.04 G to 0.97 G on the skid pad. On the company's 1.7-mile road course, Dodge says the Widebody drops two seconds off its lap time compared to the standard Hellcat, finishing about 13 car lengths ahead. We spent our time with the Hellcat Widebody on the infield road course at Indianapolis Motor Speedway. Sliding into the car, the seating position is cozy and comfortable even with a helmet on, and we have no trouble adjusting our chair and steering column to ideal placement. The infotainment display shows us our drive settings for the next few miles: the transmission and suspension are in Track Mode, steering is set to Sport, with traction set to Street. We fire up the car with an instructor in the right seat, and head out of the pit lane.
