Demon 9: Electronics, race cooling – and performance numbers?

by Patrick Rall on

The ninth teaser for the 2018 Dodge Challenger SRT Demon was posted by FCA this morning. This week, we learn about the Performance Pages, the Drive Modes and the After-Run Chiller system; while the Performance Pages and Drive Modes clarify what we already expected, the big news is the After-Run Chiller system.

Oh, we also see more appearances of the number 757, which could be a hint as to the horsepower of the 2018 Challenger Demon.

The After-Run Chiller
Many race cars have an electric cooling system which keeps the coolant moving through the engine and the fans on, after the engine is shut off.  That way, the engine is cooled for the next run; it’s a very common feature at the drag strip. I personally have two vehicles with individual switches for the water pump and cooling fans.

The 2018 Dodge Challenger SRT Demon has a similar system, but rather than the traditional cooling loop, the After-Run Chiller system pushes air through the intercooler cooling loop, with the electric fan lowering the temperatures of the intercooler as quickly as possible. As a result, the Demon will be cooled down and ready for the next run more quickly than, say, the Hellcat Challenger or the Camaro ZL1.

Demon Performance Pages
Since the Demon’s After-Run Chiller is incorporated into the infotainment system, it turns itself off when the target temperature is reached, and the driver can monitor the temperatures via the newest Performance Pages application.

The 2018 Challenger SRT Demon Performance Pages also have a real-time horsepower graph, timers for 0-60, 0-100, eighth mile and quarter mile, a G-force meter and a full suite of auxiliary gauges which display everything from boost pressure and intake air temperature to oil pressure and engine horsepower. The system lets the driver set up the Line Lock, Launch Control, and gear-by-gear shift light systems.

Basically, the Demon will have all of the Performance Pages features as the Hellcat, but the newest Challenger trimline will come with some extra gadgets and screens for the track.

In you didn’t catch it above, the Demon comes with a line lock system to help do better burnouts at the track without chewing up the rear brakes. This system works by locking the front brakes at the push of a button, which makes doing burnouts much easier, without causing excessive wear to the rear brakes.

Drive Modes
Finally (for this week), the 2018 Dodge Challenger SRT Demon will come with a unique Drive Mode system with three options – Auto, Drag and Custom.

In Auto mode, the Demon optimizes the steering, suspension, transmission, and throttle settings for the driving at any given moment, so if you are driving gently, the Demon will shift gently, but when you suddenly hammer the throttle, the accelerator and transmission will stiffen up for improved performance.

When you select Drag Mode, the Demon will shift the throttle, the transmission, the steering, and the suspension settings to those which best cater to a hard drag strip launch. The throttle response will be the sharpest, the transmission will shift the hardest and the suspension setup will allow the most front-to-rear weight transfer for the best possible traction. Drag Mode also adjusts the traction control for the best hard launch.

When you select the Custom mode, the driver will be able to preset the steering, suspension, throttle and transmission to one of three modes for a feel that he or she likes the most.

Performance numbers
When Dodge teased the Demon Crate a few weeks back, the number 757 appeared on the serial plate. This week, the image showing the cooling screen in the Performance Pages has 757 listed as the time in two different places.

This is the first time that we have seen a number repeated in the teaser images, so more than ever, we have to wonder if 757 is not the horsepower number for the 2018 Challenger SRT Demon

As readers pointed out, the video also shows example Performance Pages with a 0-60 in 3.00 seconds, 0-100 in 6.08, and a quarter mile time of 10.5 seconds at 129 mph — but these should be taken with a grain of salt; they may simply be artistic license (e.g. a mockup).
