Driveline preload lets the muscle car launch quicker and with less stress on the other expensive powertrain components.

The latest teaser for the 2018 Dodge Challenger SRT Demon offers even more reason for the muscle car to be the king of the quarter mile upon its release. The automaker believes the mean machine is the first production car ever to feature a Transbrake – a device commonly used in drag racing for quicker launches. 

Revealed:

When active, the Transbrake locks the automatic transmission’s output shaft, so the driver can build revs without creeping forward. While this would also be possible by holding down the brakes, Dodge’s setup lets drivers release the Transbrake with a simple pull of the paddle shifters. The company claims the Demon’s tech leads to 30 percent better reaction times than using the brakes.

Suddenly causing such a spike of force on the powertrain could wear out the Challenger Demon’s expensive components, so the muscle car also preloads the driveline with torque prior to launch. Dodge claims doing so reduces the chance of damaging the parts and puts the power down better at launch.

Drag racers want to put as much power onto the road as possible; so on a rear-wheel-drive machine like the Challenger Demon, the front wheels aren’t doing very much. For further weight savings, Dodge’s new muscle car features lightweight brakes that allow for the fitment of skinny wheels at the front axle.

Dodge’s engineers are doing everything in their power to make the Challenger Demon the ultimate factory-offered drag racer. The car features a high-tech launch system that lets it build more pressure in the supercharger, and when drivers do take off, an upgraded torque converter can handle the punishment. The adaptive suspension also has a setting for maximizing power transfer to the rear wheels. Plus, the team is installing a plethora of heavy-duty components for taking the higher loads.

The Challenger Demon’s teasers suggest the muscle car could make 757 horsepower (565 kilowatts), and we know the vehicle is at least 215 pounds (97.5 kilograms) lighter than a Hellcat by stripping away much of the interior. The Demon is still technically street legal, but the details so far suggest that it would be an incredibly raw machine on the road.

This is the 11th teaser outlining the Challenger Demon’s capabilities, and the slow debut is nearly over. Dodge will finally unveil its latest muscle car on April 11, during 2017 New York International Auto Show.

March 23, 2017 , Auburn Hills, Mich. - The 2018 Dodge Challenger SRT Demon leverages a performance feature that is sure to make it one for the history books. Unlocked on March 23, the newest teaser, “Lock and Load,” shares a feature that not only delivers the highest level of dedicated drag car technology offered in a production car but also, until now, could only be found in the aftermarket for "track use only" vehicles.

The 2018 Dodge Challenger SRT Demon is the first ever, factory production car with a TransBrake™. This exclusive performance feature enables the SRT Demon to produce launch forces previously unattainable by street legal production vehicles. Quicker power delivery and higher engine launch torque potential are achieved by locking the output shaft of the automatic transmission to keep the vehicle stationary until launch.

Conventional vehicle launches consist of the driver using one foot on the brake and one on the accelerator pedal to increase engine speed while holding the vehicle stationary, known as foot-brake launch or two-footing. The SRT Demon’s TransBrake feature provides improved reaction times and more consistent launches by utilizing the steering wheel paddle shifters as a launch trigger. Using the driver’s finger exclusively to trigger launch of the SRT Demon results in a 30 percent reaction time advantage over foot-brake launches.

By locking the output shaft of the transmission, the Challenger SRT Demon’s TransBrake works in conjunction with Torque Reserve to achieve:
Brake-free launches up to 2,350 RPM
105 percent increase in launch boost pressures
120 percent increase engine launch torque

To make sure the SRT Demon can take full advantage of maximum torque at launch, the TransBrake feature also includes a driveline preload process. Preloading ensures engine 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 paddle shifter is released. Preloading the driveline also provides reduced component spike loads and thus less potential of component damage. The overall result is faster acceleration at launch, better 60-foot times and improved quarter-mile times.

The TransBrake feature also compliments the SRT Demon’s new lightweight brake package, designed to enable the use of narrow front-runner wheels at the drag strip. With TransBrake holding the SRT Demon steady, more torque is available via higher engine rpm without fear of overwhelming the reduced grip of braked front runners. This gives the SRT Demon up to 40 percent more available launch torque compared to vehicles with front runners using a foot-brake launch.
