The all-new, 2018 Dodge Challenger SRT Demon, revealed at the New York International Auto Show last April, is a peerless beast of a production car, capable of sprinting to 60 mph from a stop in as little as 2.3 seconds and blazing through the quarter-mile in less than ten.
Granted, to be that quick, the SRT Demon has a few tricks up its sleeve. The new model has wider rubber than SRT’s last high-performance muscle car, the Hellcat, and an available “Demon Crate” packed with tools and parts to help lop precious time off at the drag strip is available. The crate includes things like a high-performance air filter, skinny front wheels, passenger mirror block-off plate, and a Powertrain Control Module that allows the Demon to run race gas, unlocking its full, advertised 840 horsepower.
But the wizards at SRT didn’t stop there. Two features in particular – the SRT Demon’s factory transbrake, and its special Torque Reserve system – help the new performance model achieve a near-perfect launch every time. The transbrake locks the transmission by engaging first and reverse simultaneously, keeping the car stationary until the driver is ready to launch, while Torque Reserve keeps the supercharger precharged with 8 psi of boost at engine speeds up to 2,350 rpm.
It’s all quite complicated, not to mention highly unusual for a production car, so to better understand how the 2018 Dodge Challenger SRT Demon leverages technologies like these to deliver a remarkable launch, watch the video above from Engineering Explained.
