Spooky, but not so scary: NASCAR's zombie cars
As one of the oldest and most important championships in American motorsports, NASCAR has produced countless unforgettable stories that have helped shape its lore. At its heart, however, the series has always been defined by the unique bond between fans, teams, manufacturers, and sponsors.
And like any long-running series, though, NASCAR is constantly evolving. Progress often means leaving parts of its past behind, be it through the introduction of new race cars, the retirement of familiar nameplates, or even the departure of entire manufacturers.
While change keeps the series moving forward, it also creates fascinating reminders of earlier eras that continue to appear long after their official time has passed.
One of the most unusual examples of this is the phenomenon known as the "Zombie Car". The term refers to cars that continue competing even after their road-going counterparts have been discontinued or after their manufacturers have exited NASCAR. It can also describe older body styles that remain on track after a manufacturer has shifted its support to a newer model in a particular series.
The idea may sound strange, but it remains surprisingly relevant: for example, one must consider that the Chevrolet Camaros currently racing in the series are “zombie cars” themselves, as Chevy ended production of the Camaro road car counterpart in 2023! And they are far from being the only example…
Ford Thunderbird (1998-99’)
From 1978 to 1997, the Ford Thunderbird was Ford Motor’s primary weapon in NASCAR, snatching for the brand 176 Cup race wins. Bill Elliott won the 1988 championship driving a Thunderbird, and so did Alan Kulwicki four years later. Thunderbirds also powered Ford Motor to NASCAR manufacturers’ championships in 1992, ’94 and ‘97.
But in 1998, Ford introduced a new model in the category, based on its best-selling Taurus. The shift would be significant not only for the brand but also for Ford’s NASCAR customer teams, who initially viewed the discontinuation of the more nimble Thunderbird in favour of the massive third-gen Taurus with suspicion.
These concerns gained even more ground when data from pre-season wind tunnel testing showed that the Taurus had significantly more drag than the older Thunderbird, something that negatively affected the car’s performance, especially on superspeedways.
Based on this, some of Ford’s racing customers simply decided to stick with the Thunderbird body style for 1998, with teams such as Roush Racing, Cale Yarborough Motorsports, and Triad Motorsports being just a few of the ones that opted for the old machinery in some races of that season.
The last Thunderbird Cup appearance took place in 1999, when Rick Mast drove the Yarborough Burdette Motorsports #98 car to an incredible 9th-place finish in the Bud Shootout (the equivalent of today’s early-season Clash).
Pontiac Grand Prix (2004–05’)
One of the most successful manufacturers in NASCAR history, with 154 victories in the series’ premier category alone, Pontiac became a name closely associated with NASCAR’s heritage.
The early 2000s brought some fine results for the brand, including propelling Tony Stewart to his first drivers’ championship in 2002; but that was not enough to prevent far more dramatic events from unfolding behind the scenes.
The first signs of a serious internal financial crisis were beginning to shake the foundations of Pontiac, and to cut losses, the company was forced to make a sharp adjustment, which would involve not only a restructuring of its production line but also a reassessment of certain special programs - such as the one linked to NASCAR.
Thus, at the end of 2003, the company made it clear that it would not renew its contract with NASCAR for the following season, leaving a void that would quickly be filled by rivals Ford, Dodge, and Chevrolet.
However, this did not mean an immediate dismissal of Pontiac from NASCAR, as small privateer teams, without any factory support, soldiered on with the brand’s Grand Prix model. In the Cup, Pontiac would have its swan song in the 2004 NASCAR All-Star Race, driven by Andy Belmont.
In the Busch Series, the Pontiacs would survive well into the 2005 season, as DCT Motorsports kept its Grand Prix running until Bristol’s Food City 250.
Dodge Intrepid (2005–06’)
The resurgence of the Intrepid in NASCAR during the 2005 season bore striking similarities to the Thunderbird/Taunus case a decade earlier: less-than-convincing computer and wind tunnel data, which showed that the new car underperformed the old one in specific racing scenarios. But the Dodge story has some unique elements that make it a more spicy tale.
The first was that the revolt would reach some of the series’ highest echelons, with Penske demonstrating the efficiency of the old model two years after it had been discontinued by Dodge!
During the 2006 Auto Club 500, the team decided to sideline its Chargers, fielding instead rebuilt Intrepids, and, to everyone’s surprise, Kurt Busch drove the car to the pole (187.086 mph), embarrassing not only other teams that had decided to stick with the Charger for the race, but also Dodge itself.
This would lead to the second difference in the story: unlike Ford, which had privately reprimanded the teams that opted for the Thunderbird in ’98, Dodge was scathing in its comments about the return of its older cars to the series.
The point was clear: what did the competitiveness of a two-year-old model matter, one that, despite bringing good visibility to the company, could not be purchased by consumers at a Dodge dealership?
At the end of the day, it wasn’t just about victories, but also about sales and revenue, and even with its serious aerodynamic problems, the Charger was destined to be the brand’s flagship model in NASCAR.
However, not even this reprimand would be enough to change the teams’ stance; they simply dismissed and defied Dodge’s warnings about using the Intrepid, continuing to field the car in select races until mid-2006, when the car finally had its Cup license revoked.
Dodge Challenger (2013–18’)
Perhaps the most iconic example of a “zombie car” in the last decade was the one staged by Dodge. This story began with the introduction of the Gen-6 cars, which replaced the former “Car of Tomorrow” (CoT) specifications as NASCAR’s standard regulations from 2013-21’.
This move was prompted by the organisation’s desire to return to its roots, featuring machines that looked more like production cars than the silhouette-styled CoT.
Dodge indeed developed a new Charger for these new specifications; however, financial problems within the Dodge/Chrysler group, combined with the loss of its main partner in the series (Penske, which struck a deal with Ford), led to the project being shelved and, consequently, Dodge’s decision to withdraw completely from the series at the end of the 2012 season.
Due to the Cup Series’ extremely strict body rules and adherence to the new Gen-6 regulations, CoT Dodges were not allowed to race in the series from 2013 onwards. But in the more open environment of the Nationwide/Xfinity Series, these cars could still be fielded, especially by low-budget teams looking for reasonably competitive cars - though for obvious reasons, they would not have any factory-backed support.
In 2013, one full-time (Harmon-Novak Racing) and four part-time (NDS Motorsports, Shepherd Racing Ventures, Vision Racing, and Young Racing) squads entered Challengers in the Nationwide Series, with the number gradually dwindling until 2018, when the last sedan-type Dodge entry in NASCAR occurred, driven by MBM Motorsports’ Carlo Long in the season-closing Homestead Ford EcoBoost 300.
Toyota Camry (2019–20’)
And in one of the most recent cases of “zombie cars,” it would be Toyota’s turn to put on an interesting show, once again with the Xfinity Series as the backdrop.
The company’s decision to update its package for the series starting in the 2019 season - switching from the traditional Camry platform to the Supra - was one of the most significant moves by manufacturers in NASCAR in recent decades, meaning that for the first time in its history, a foreign company fielded two distinct sedan body styles in the series’ two main categories (in this case, the Cup would continue to use the Camry platform).
However, to get their hands on one of the new Supras, each team would have to shell out a hefty sum - a problem for the less-wealthy members of the grid. This ensured that when the 2019 season kicked off, some teams opted to race their old vehicles (still allowed under series regulations), most notably MBM Motorsports and Hattori Racing.
Both squads rotated between the Supras (which were usually reserved for superspeedway events) and the Camrys until late 2020, when the latter was officially retired from the series.
