Dodge Challenger Demon Has Industry-First Launch Assist That Prevents Wheel Hop
Brutal launches for everyone!by Ciprian Florea, on
Dodge has already launched seven teasers for the upcoming Challenger SRT Demon and it has been pretty clear that the muscle car was designed to destroy any competition at the drag strip. Still skeptical about that? Well, it’s time you find out that the Demon is equipped with a range of race-hardened parts and that it has tech that protects the driveline from damage during hard launches. You can also forget about wheel hop, as the car’s Launch Assist system uses the wheel speed sensors to watch for signs that the tires are slipping or sticking.
What this means is that if slip is detected, the SRT Demon’s control module reduces engine torque to maximize traction almost instantly, without the driver having to lift his foot off the throttle. Launch Assist also reduces loads in the driveline from wheel hop by more than 15-20 percent, thus reducing component damage. This is an industry-first feature and should help the Demon deliver impressive quarter-mile runs.
Dodge also upgraded several components in order to improve durability and power delivery. For instance, it upgraded the torque shaft by using high-strength steel and a 20-percent increase in tube thickness and heat treated stub-shafts, which increases torque capacity by 15 percent. A new differential housing made from heat-treated aluminum alloy also enhanced torque capacity by 30 percent. Additionally, upgraded 41-spline half shafts deliver 20 percent increased torque capacity. This was accomplished through the use of increased diameter high-strength low alloy steel and eight-ball joints that improve torque capacity while reducing operating temperatures by more than 86 degrees Fahrenheit.
Drivetrain upgrades aside, Dodge revealed that the driver will be able to use a new four-point harness bar at the track. It’s made by Speedlogix and it can be installed without cutting or drilling anything in the car, as mounting points were made accessible in the back. As a quick reminder, the Demon doesn’t have rear seats.
Stay tuned for another teaser next week and don’t forget to tune in for the full update from the 2017 New York Auto Show in April.
