By the time the first two Factory X cars were built, the timing couldn’t have been worse. Detroit had already discontinued production of the Camaro and Challenger models on which the class was based. That made the category outdated before it began, much like introducing a racing division for Edsels in the 1960s.
For those trying to keep score, only 11 Factory X cars have been constructed since the class debuted. Thirteen drivers have strapped into those machines, but the cost, complexity, and limited supply of parts have prevented wider adoption. The U.S. Nationals entry list of just four cars was the clearest sign yet that the class lacks momentum.
The struggles extend beyond car counts. Builders faced lengthy delays in receiving chassis and critical components. Supply chain issues slowed delivery, and when the cars did appear, inconsistent rule enforcement and occasional disqualifications further weakened the class. Manufacturer support has also been lacking, since the category’s chosen platforms no longer exist on showroom floors.
Factory X was originally billed as a bridge between Factory Stock Showdown and Pro Stock, offering drivers and teams a logical step up the performance ladder. In theory, it was a class that could showcase supercharged factory engines in modern chassis with recognizable bodywork, preserving brand identity while providing Pro Stock-level competition. In practice, it became a patchwork solution that never gained traction.
The problems echoed earlier frustrations in NHRA’s handling of Pro Stock. EFI had been delayed for years because the strongest teams resisted change, and even when adopted, it came only after long lead times. That same slow-moving culture shaped Factory X. Rules were announced before the infrastructure was ready, parts weren’t available, and the factories behind the cars moved on.
Unlike the cornerstone categories—Top Fuel, Funny Car, Pro Stock, and Pro Stock Motorcycle—Factory X is not a permanent class. It doesn’t carry the same legal ramifications that Pro Stock Truck once presented, when NHRA abruptly discontinued it in the 1990s and found itself in court. Factory X isn’t an official professional category, which gives NHRA more freedom to pivot, but also leaves the class without the permanence or protection of the sanctioning body’s established divisions.
The lack of planning left the class vulnerable from the start. Without strong aftermarket support and with Detroit abandoning the Camaro and Challenger, the backbone of the class had already been cut. The result was a category that looked irrelevant even before its first race.
To better understand how Factory X fits into NHRA’s broader history of class management, I reached out to Hall of Fame announcer and revered statistician Bret Kepner. It’s one thing to have an opinion, but it’s another to form one on facts—especially those not readily available. His insight underscores the importance of grounding this discussion in hard numbers and historical precedent, not just reactionary takes.
In an earlier era, NHRA would have likely taken a different approach. The sanctioning body once had little hesitation in eliminating perceived struggling categories such as Top Gas or Modified when they no longer served the sport. If that standard still applied, Factory X would already be gone, and the parade of protest would be a short one.
BOBBY BENNETT: FOUR CARS, ZERO DIRECTION – IT’S FACTORY X
Four cars. That’s all that entered NHRA’s Factory X division at the U.S. Nationals, drag racing’s most prestigious event. The turnout underscored the ongoing struggles of a class plagued by short fields, disqualifications, rule missteps, and delays since its debut two years ago.
Despite heavy promotion, only 11 different Factory X cars have made competitive runs. The class has endured a string of missteps that have prevented it from fulfilling its intended role as the future of Pro Stock.
Factory X traces its origins to the Factory Stock category introduced in 2012. That class initially featured supercharged Ford Mustangs, followed by Chevrolet’s COPO Camaros and Chrysler’s Drag Pak Challengers. The emergence of those cars prompted NHRA to reexamine the future of Pro Stock, which was already losing audience support.
For those not in the know, Factory X wasn’t really designed to be a class as much as it was intended to be part of a larger plan to revitalize NHRA Pro Stock. The sanctioning body developed a three-stage plan to update Pro Stock. Electronic fuel injection was scheduled to debut in 2015. In 2016, the class would incorporate drivetrain technology from Factory Stock. By 2017, Pro Stock cars were to be powered exclusively by supercharged Factory Stock engines.
That plan fell apart almost as soon as it began. While EFI finally arrived in 2015, it came only after decades of resistance from teams unwilling to abandon carburetors and lose the performance advantages they had spent years perfecting. The next step, integrating Factory Stock powerplants into Pro Stock chassis, was scheduled for 2016 but stalled after objections from team owners. By 2017, the entire plan was scrapped, leaving Pro Stock unchanged and in deeper need of a refresh.
For those who followed the politics behind the scenes, the collapse of the plan was no surprise. The Pro Stock team owners refused to give up control, blocking NHRA’s attempt to modernize the class. With Pro Stock’s transition blocked, NHRA shifted its attention to building a new division instead, hoping Factory Stock could evolve into something bigger.
The result was Factory X, a series built on modern muscle cars with stock-appearing body panels. The concept made sense: put Mustangs, Camaros, and Challengers on the track in a way fans could recognize, and let the engines provide the performance. For casual observers, it looked like the same cars on the street—only quicker. For racers, it offered a way to stay connected to Detroit’s factory programs.
But once again, execution didn’t match the vision. NHRA mandated the use of stock body panels, yet no aftermarket supplier was producing them. Builders couldn’t find parts to meet the rules, leaving the series hamstrung before it had a chance to grow. The misstep delayed what would become Factory X by more than two years.

Many in the pits quietly acknowledge the class may never reach sustainability. Without new manufacturer involvement, stronger aftermarket infrastructure, or significant cost reductions, the model risks fading from relevance altogether.
For those who remember why Factory X was conceived, the disappointment is clear. It was never supposed to be a standalone class but rather the foundation of a revitalized Pro Stock. Instead, it has become a cautionary tale of what happens when planning falters, execution lags, and Detroit abandons the very cars the series was built upon.
At the end of the day, Factory X was supposed to be NHRA’s answer to fading Pro Stock relevance, but instead it has become a mirror of the sanctioning body’s own indecision.
NHRA called it the bridge to Pro Stock’s future, but Factory X may already be a dead end.
