Not crazy about the fact that they brought back the "Demon" name without slapping the "Dart" name on the front of it.
A few weeks ago, the drag strip hosted a private hoedown for members of the Legions of Demons car club […] Crucially, the event was produced by a drag strip surface prep company called Mass Traction, which also supervised track maintenance for Fiat-Chrysler during the Demon's development and knows how to maximize grip for the car. Forty-two stock Demons showed up for a run at the record, joined by five modified models for the hell of it. The result? Though no one topped Pritchett's mark, 38 of those stock cars made it into the vaunted nines. Unfortunately, the other four suffered catastrophic rear-end failures at launch, as did one of the modded cars.[…]The problems with the stock Dodge Demons are more concerning. […]It was our conversation with Mass Traction owner Brandon Mass that shed the most light on the matter. He told us he treated the drag strip surface at Houston Raceway to his company's highest standards for the event, getting as close as possible to the laboratory conditions he created to help max out the Demon during its development. And he also stationed the cameraman in the perfect position to capture the carnage, because in his words, he "knew it was gonna happen."Mass pointed out that at any racing event, you're going to have at least one or two outliers that suffer some sort of catastrophic failure. It's just the nature of the game. But he also noticed something important as the Dodge Demon underwent testing: Cars that ran full-strength passes on lower-traction surfaces were more likely to break when they returned to perfectly-treated pavement delivering maximum grip.There are a number of reasons why that could happen. Mass hypothesizes that the wheel and tire shake generated when launching on a less-than-ideal surface is causing microscopic stress fractures in the rear differential. Put that car back on a sticky surface that doesn't allow wheel spin or hop to dissipate any power, and the weakened structure suddenly experiences the full force of the launch.
