The 2018 Dodge Challenger SRT Demon won’t get away from the starting line at all without beefier driveline components. We don’t know the actual torque numbers yet, but we do know it will have more twist than the Hellcat’s 650 lb-ft. Well, we don’t actually know that, but we’d bet on it.
Today’s bit of info concerns putting all of that power to the ground. The Demon will come with an upgraded prop shaft — increasing torque capacity by 15 percent over the Hellcat through the use of high-strength steel — a 20 percent increase in tube thickness and heat-treated stub-shafts. The differential housing is made with heat-treated A383 aluminum alloy and a higher strength gearset, good for a 30 percent increase in capacity. Finally, the upgraded 41-spline half-shafts are made from high-strength, low-alloy steel, improving torque capacity 20 percent.
To keep those wheels from hopping on hard launches, the Demon uses its launch assist function to watch for slip. If spin is detected, the control module reduces engine torque momentarily without the driver having to lift. That’s cool, but it takes a little of the fun out of it, no?
Lastly, the Demon is available with a four-point harness bar from Speedlogix, for use while at the track. The Demon’s rear seat is deleted and mounting points are accessible, so customers can install it themselves without drilling or cutting. The bar goes for $800 online, but we’re not sure if that’ll be the option price. We’ve emailed Dodge to check and we’ll update when we hear back.
And for the fans, Dodge is going to invite 10 lucky enthusiasts who use the hashtag #DodgeDemon on social media to the Demon reveal at the New York auto show.
Check back next Thursday for more SRT Demon news — we have about four or five more of these before the final reveal on April 11.
