It’s been a while since we last reported on the upcoming Dodge Challenger SRT Demon, and in that time, the carmaker has released four new videos of its hotter-than-the-Hellcat version of the Challenger.

Features number eight focuses on the Demon’s Performance Pages, which are part of the car’s Uconnect infotainment system, which includes am 8.4-inch touchscreen. As the name suggests, the feature provides loads of driver-oriented information, grouped into various modes – Auto (Street), Drag and Custom.

Depending on which is selected at the time, drivers will get to see a real-time graphic display of engine horsepower and torque with gear changes, supercharger intercooler coolant temperature, peak lateral and longitudinal g-forces and various other temperature sensors.

That’s not all because hey will also be able to select a line-lock function, set rpm-adjustable launch control and by-individual-gear-adjustable shift light. Last but not least, data logging for 0-96 km/h (0-60 mph), (0-160 km/h) 0-100 mph, 200 m (eighth-mile) and 400 m (quarter-mile) elapsed time as well as vehicle speed are all part of the system.

In video number ten titled No Pills, the focus is on the Demon’s distinctive “staged” exhaust note, which is the result of an advanced torque reserve launch system – the first ever designed for a drag race application on a production car, according to Dodge.

What is torque reserve? Dodge explains that the Demon allows more air flow through the engine before launch. This allows the supercharger to build its rpm without the engine’s torque overwhelming the brakes and spinning the rear tires. This function is active when the car is set to Launch mode and the engine is revving over 1,000 rpm.

In closer detail, torque reserve closes the bypass valve on the supercharger, effectively “prefilling” the supercharger. It also manages the flow of fuel to the cylinders and changes spark timing, briefly cutting fuel flow to selected cylinders if required. This is what creates that unique engine note, and as Dodge puts it, “if you know you will hear extreme performance, but those who don’t will think something is wrong with the engine.”

Next up, video number 11, Lock and Load showcases the Demon’s TransBrake feature, which enables the car to “produce launch forces previously unattainable by street legal production vehicles.”

The system works in conjunction with the aforementioned torque reserve to achieve three things – brake-free launches up to 2,350 rpm, 105% increase in launch boost pressures and 120% increase in engine launch torque.

It also preloads the driveline to ensure the engine’s torque is applied through the entire driveline all the way to the rear wheels. The result is full engine torque delivery where the tires touch the ground 150 milliseconds after the driver sets off.

On the mention of launching the car off the line, TransBrake also abandons the foot-brake launch technique, where one foo is t on the brake and the other on the accelerator pedal. Instead, the steering wheel paddle shifters act as a launch trigger, which provides a 30% reaction time advantage over foot-brake launches.

Finally, the latest video, No Ice, highlights the Demon’s liquid-to-air charge air cooler chiller system, claimed to be the first for a factory production car. Despite its fiery name, the Demon needs to ensure the engine’s charge air cooling system is working at its most optimum so the engine performs “like it is running in the cold Alaskan air, even after a day of runs down the strip on a hot summer day.”

Conventional cooling methods consist of simply using air or coolant to reduce the air induction temperature as it is passed through the charge air cooler. However, in Drag mode, the Demon’s interior air-conditioning system does double duty, making sure passengers are kept cool while chilling the engine’s charge air cooling system. Dodge says this provides up to 7.2 degree Celsius reduction in intake air temperature.
