2018 Dodge Challenger Demon Gets Anti-Lag Wizardry

Demon to use newly developed anti-lag Launch mode in Dodge Challenger Demon


Debuting in the upcoming New York Auto Show, the Dodge Challenger Demon is to be teased as the most ferocious Dodge vehicle ever. With a teaser campaign that started this week after the Detroit auto show, the latest Demon release is all about how the street-legal drag car uses its newly developed anti-lag launch mode.

Generally, anti-lag is associated with heavily turbocharged motors. To keep the turbochargers coiled, the engine management system sends few droplets of ignited fuel through the turbocharger, thus it spins and keeping it in boost. These systems are usually found in race cars such as you would see in the World Rally Championship and more recently in Formula Drift where these systems have such a habit of shooting foot-long flames out of the exhaust.

The Demon’s anti-lag system, however, will definitely be a little different.

Accordingly, Dodge the new launch mode is more often an “advanced torque reserve launch system” than your straightforward anti-lag. Unlike the traditional systems generally where fuel is sent through to keep the turbocharger spinning, Dodge’s Demon will push air through its intake system and close off the supercharger’s bypass valve, “prefilling” the supercharger. In other words, the system spools the supercharger up for the toughest launch possible.

Moreover, Dodge states that the torque reserve system will also “manages the fuel flow to cylinders and changes spark timing. Equivalently, it also balances engine rpm and torque; the Challenger SRT Demon’s powertrain controller will briefly cut fuel flow to selected cylinders. This will create the noticeable change in the exhaust tone. The controller also advances or retards the ignition timing to fine-tune the engine rpm/torque balance.”

This system then dumps all the available torque to the Nitto-supplied 315/40R 18 NT05R street-legal drag radials and sends the supercharged Demon down the drag strip as fast as possible. Dodge claims this accumulation of parts of anti-lag wizardry will allow the upcoming Challenger SRT Demon to “generate more than 35 percent higher launch force than a [standard] Challenger Hellcat.”

Inappropriately, unlike other anti-lag systems, because of how Dodge tuned the Challenger SRT Demon, you will not find any flames shooting out of the exhaust, as evidenced by the video of the car smoking a drag strip.

The Dodge Challenger SRT Demon will have its debut at the New York Auto Show Tuesday on April 11. However, in between, there are five more teasers to get everyone excited about its upcoming release.
