Demon 1st Ever Road Car with a TransBrake
We learned this morning that the 2018 Dodge Challenger SRT Demon will be the first ever road-going production car to feature a factory TransBrake – allowing the new Mopar monster to leave the line harder than any street legal car to come before it.
The majority of cars running the quickest times at the drag strip are often equipped with a transbrake, which allows the driver to increase engine RPM at the starting line without moving the car and without smoking the rear tires. As the name suggests, the transmission holds the engine power, so while the engine is spinning the front of the transmission – the back of the transmission is not trying to spin the tires with the transbrake engaged. In these built racecars, a transbrake helps the driver launch harder than when just trying to hold the car in place with the brakes, leading to more launch power, quicker short times and quicker elapsed times.
The 2018 Dodge SRT Demon will be the first road-car to feature a transbrake from the factory, adding to its resume as the greatest street-legal, drag strip-ready production car of all time.
Here is a quick rundown of how the TransBrake system in the 2018 Dodge Demon works. After the burnout, the driver heads towards the starting line and activates the Launch Control system. This enables the Torque Reserve system (call it a 2-step or anti-lag system if you prefer) and the TransBrake, so once the new Demon is in the staging beams, the driver engages the TransBrake with the left shift paddle. Once engaged, the TransBrake locks the transmission output shaft while allowing the driver to increase engine RPM up to 2,350rpm, but the added stress of that extra RPM doesn’t go beyond the 8-speed automatic transmission.
When the driver lets off of the shift paddle, the Demon’s TransBrake releases all of that power, funneling it to the rear wheels in just 150 milliseconds and helping the newest Challenger to blast off harder than any factory-stock car in the world. According to today’s announcement, this system allows the Challenger Demon to launch with 105% higher boost pressure and 120% more torque than a car launching with only the brake pedal.
While the aftermarket has long turned to the transbrake to get the best launch forces at the drag strip, the Demon’s system has a feature which you won’t find in the quickest cars at your local track. The 2018 Challenger SRT Demon TransBrake has a unique preload feature, which allows some of the power to travel through the transmission to the rear wheels. There isn’t enough power passed through the TransBrake system to spin the rear tires or to push the locked front tires through the staging beams, but it is enough power to help prevent the violent blast of power that you get with a traditional transbrake. More importantly, in addition to helping to protect the drivetrain components behind the transmission, the TransBrake preload system helps get power to the wheels more quickly on launch – cutting the power delivery time by about 30%.
When you consider all of the advantages of the 2018 Dodge Challenger SRT Demon TransBrake system, it will contribute to prolonged durability of the drivetrain components, improved short times and better ETs thanks to the increased power levels at the point of launch.
Of course, the newest Demon teaser comes with another mystery, as the license plate in the Demon shown above has more nonsensical math, but numbers aside – the Demon has a TransBrake and that is going to play a big part in making the 2018 Challenger the most drag strip-capable production car to ever hit the street.
And it will make its grand debut in just 20 days, so in less than 3 weeks, we will finally have all the details on the 2018 Dodge Challenger SRT Demon.
An owner of a gorgeous Plum Crazy 2016 Dodge Challenger SRT Hellcat has made a short video detailing the real world performance differences between the red key and the black key – essentially showing us the difference between 707hp and 500hp Plum Crazy 2016 Dodge challenger SRT Hellcat in a 50-100mpg run.
When Dodge released the 2015 Challenger SRT Hellcat with the 6.2L supercharged Hemi, they introduced their two-key system – with a black key which limits the power to 500hp and the red key which unlocks the full 707hp potential of this Mopar monster. It is easy enough to say that the difference in using the two keys is 207 horsepower, but how does that impact real world performance?
One Hellcat Challenger owner headed to Mexico with both keys to see just how much of a difference it makes when using the two keys in terms of real world performance.
Red Key vs Black Key, 50-100
In the video below, Paul (the owner) of the 2016 Dodge Challenger SRT Hellcat explains his process and he shows how the infotainment system screen varies when the red key or black key is in use, with the varying features which are locked out in the absence of the red key. More importantly, this Hellcat Challenger owner makes a series of hard runs starting at 50 miles per hour with each key, noting the time taken to reach 100 miles per hour.
Dodge will officially unveil the 2018 Dodge Challenger SRT Demon on April 11th at 7:30 PM ET the night before the New York International Auto Show. Want in on the action?
