Mining the Demon Performance Pages

by Patrick Rall on

While this week’s official news covered Drive Modes, the After-Run Chiller, and Line Lock, the end of the Demon teaser video caught the attention of the Mopar community.

During the last few seconds, a spread of screens for the Demon’s Performance Pages system flash across the screen. This quick glimpse might unlock all sorts of answers to this new Challenger’s greatest mysteries, but I think that much of the information included is nothing more than random information added for display purposes.

Even though we don’t think that these screen shots answer the big questions on the 2018 Demon, they still show off high tech measurement system of the newest Dodge Challenger, so today, we take a look at each of these screens.

This first screen is likely one of the configurable gauge screens (above), showing the horsepower, the g-forces, the boost pressure and the gear selection – none of which have any key numbers in this shot.

The second screen shows the dyno graph which debuted on the Durango SRT. During the course of the video, we see the line climb a bit, but that portion ends before we see any significant numbers.

The third screen in the Demon Performance Pages video shows auxiliary gauges. The most significant numbers are the 0-60 or 3.0 and the 0-100 or 6.08. The Hellcat Challenger gets from a stop to 60 in the mid 3-second range and 100 in the 7-second range, so with the new Demon, those numbers seem very possible.

The fourth screen shows the performance timer readout, with strangely blurry numbers where they matter the most. It looks like a 3.0 0-60, a 6.9 0-100, an 8th mile run of 6.6 at 125mph, a quarter mile run of 10.5 at 129mph and a braking distance of 220ft when stopping from 128mph. Most of these seem possible for a car which is a quicker version of the Hellcat Challenger, but the speeds don’t make sense. 125 miles per hour in the eighth mile would be incredibly fast for a 6.6 run, while 129mph in the quarter mile (especially after hitting 125 in the 8th) would be unusually slow. In other words, the times could prove to be legitimate, but the trap speeds don’t seem right.

The fifth and sixth screen both show more auxiliary gauges without any significant figures.

The seventh, eighth, ninth and tenth still images of the 2018 Challenger SRT Demon Performance Pages show graphs which could be revealing key information, but the line in the graph remains the same in every image! While the numbers on the side change, the line remains the same in every graph, so it’s most likely that a random line was added to make the graphs more interesting.

In fact, if you look at the measurements, there is almost no way that the new Demon could be experiencing this numbers. For instance, the Intake Air Temp gauge is hovering around 125 degrees and it spikes to about 225 degrees, and while an intake temperature of 125 is possible, 225 is not.

On the Boost Pressure screen, there is a Demon logo blocking out the peak, but it looks like it tops out somewhere around 15psi based on the other graphs. That is a feasible number for the supercharged Demon.

On the Air/Fuel Ratio screen, the line hovers along the Stoich point, but at the point where the line reaches its highest point, the car would be far too lean to be safe for the engine.

Finally, the IC Coolant Temp levels spike in an unusual manner – leading me to believe that this isn’t a line graph which we would see in a properly-tuned, supercharged Dodge Demon.

The eleventh image from the Demon Performance Pages video shows the G-meter, with 1.45g of launch forces— reasonable for a high performance muscle car with sticky tires.

The twelfth screen shows the dyno graph screen. The scale on the left tops out at 700 and it climbs by hundreds, and it appears as though both horsepower and torque top out around halfway point between 700 and where 800 would be. Combine that with the fact that the time on all of these screens is 7:57, and we have to wonder if the rumors of the mid-700hp range might be true.

The next three screens show the various settings of the Demon’s Drive Mode setup screen and there is nothing huge to be learned from these.

Take special notice of the fact that the “Power” numbers have been removed, but in each of the screens, we see different variables representing the numbers. We see XXX, XYZ and YYY – leading me to believe that the Demon might have three different power settings rather than two.

We can also see the mention of the Red Key, suggesting that the Demon will use a multi-key setup, and we can see that there is a Valet Mode and an Eco Mode – for those folks who want to get great mileage on the way to the track.

Finally, the last image of the Demon Performance Pages application shows some of the drag race options, including Launch Control, the Shift Light, the Race Cool Down and the Line Lock system. We have already talked about Launch Control, the Shift Light settings and the Line Lock, but the Race Cool Down has not been referenced by name. This is presumably the After-Run Chiller system.

Again, while this doesn’t solidify any of the specifications or capabilities of the 2018 Dodge Challenger SRT Demon, these still shots almost certainly include some hints on the new Demon – we just have to wait and see which information is accurate and which information was simply tossed in for display purposes.
