How Many Backup Cars Do NASCAR Teams Have?

When you watch NASCAR on TV, it may look as though the whole thing just happens with ease, but what you don’t typically see is the huge logistical and mechanical operation that goes on behind the scenes. We get snapshots of this, perhaps best typified during a thrilling pitstop in which teams of professionals work at break-neck speeds to get their team cars fit and ready to get back into the fray.

NASCAR’s use of backup cars is a blend of strategy and necessity. Teams meticulously prepare these vehicles, balancing cost and technical precision. Backup drivers stay ready for action, while dedicated crews ensure seamless transitions, highlighting the sport’s complexity and teamwork

Besides what we see on TV, there’s more to the logistics than you realize. One big part of the operation is bringing not just the main cars for the race, but the backup cars as well. But how many of these cars are there? That’s what we intend to find out.

What is a Backup Car in NASCAR?

As the name suggests,

a NASCAR “backup car” is a spare vehicle that teams bring in case something goes wrong during either the practice or qualifying sessions before the main race itself.

According to NASCAR rules, teams are allowed to have backup cars to use if their main car is damaged or crashes in practice or qualifying, but once the green flag waves on race day they are no longer allowed to switch to backups, regardless of what happens.

There’s one further stipulation to the NASCAR backup car rules, namely that should the team go to a backup car for race day, they have to go to the back of the field to start. That’s a pretty big penalty, which is why NASCAR teams will do everything humanly possible to avoid having to switch to a backup car for race day.

How Many Backup Cars Do NASCAR Teams Have?

The most common situation is that NASCAR teams will have just one backup car. Given the extreme cost of building and maintaining the cars in a NASCAR team, it’s understandable that teams don’t typically bring more than one.

For some teams, even one backup car is too rich for the budget, and they are forced to do everything with their main car, or ultimately do nothing at all.

To keep up the main car of each driver, teams must safely transport the vehicles, crew and equipment from track to track in special haulers. The sheer size and complexity of the logistical operation makes owning a large number of backup cars prohibitively expensive.

What’s more, at the time of writing, teams are still suffering under ongoing parts and component shortages that are making supply chains even more costly than usual, not to mention timelines more stretched and stressful.

As we mentioned above, however, backup cars can’t be used mid-race. Therefore, crashes or other damage done after the green flag waves to start the race have to either be dealt with there and then, or the driver withdraws.

The backups can be brought in during practice or qualifying, but will result in a driver starting right at the back of the field…a penalty that some drivers and teams just can’t afford in such a competitive season. NASCAR isn’t like Formula 1 has been in the past decade, with just a small handful of drivers/teams winning absolutely everything.

How Are Backup Cars Transported?

NASCAR vehicles and backup cars are transported in huge haulers that some commentators have described as “office blocks on wheels.” If you suppose that driving a NASCAR vehicle is a challenge, then you might want to consider how hard it is to drive these monster haulers.

These 80,000-pound rigs are big enough to carry two cars each, as well as sleeping areas for the driver (and co-driver on long trips), as well as office spaces in the trailers for the teams to use on race day.

The transporting operation is arduous and complex to say the least. Most of the NASCAR tracks in a season (about half) are on the east coast of the US. The others are divided between the Midwest and the West.

The latter presents the greatest challenges, which is why teams have separate haulers to manage the swing out west, which usually starts in Phoenix, Arizona, and finishes in California. It takes days to fully pack and unpack the haulers between events, which makes long-distance transport routes all the more critical when it comes to timing.

Cars aren’t even whole during transport, traveling instead with many of the constituent parts in tow, ready for assembly by the team when everything has safely arrived at the track.

The process of unloading and assembling all the necessary gear and components is a serious task, which is why teams have to arrive in their haulers so early to get everything ready for practice, qualifications, and then the racing weekend itself.

The Evolution of Backup Cars in NASCAR

The concept of backup cars in NASCAR has evolved significantly over the years, mirroring the sport’s advancements in technology and regulations. Initially, backup cars were a rarity, used only in extreme cases.

However, as NASCAR racing intensified, the presence of a backup car became a standard part of a team’s arsenal. This shift was partly due to increasing speeds and the consequent rise in crashes and mechanical failures.

Notably, pivotal moments in NASCAR history, where backup cars turned potential disasters into triumphant wins, have underscored their importance.

Today, the backup car is not just a contingency plan; it’s an integral part of a team’s strategy, reflecting the relentless pursuit of reliability and performance in the face of the sport’s inherent unpredictability.

Technical Specifications of Backup Cars

Backup cars in NASCAR are not mere replicas of the primary race cars; they are marvels of engineering, meticulously prepared to meet exacting standards.

Although they must adhere to the same technical regulations as the main cars, teams often use backup cars as an opportunity to experiment with different setups or adjustments, refining their racing strategies.

This means a backup car might have slight variations in its aerodynamic profile, suspension tuning, or engine calibration. The goal is to ensure that the backup car can seamlessly replace the primary car without compromising performance.

This meticulous attention to detail highlights the blend of precision and adaptability that characterizes elite NASCAR teams.

Cost Analysis: Maintaining Backup Cars

The financial implications of maintaining a backup car in NASCAR are substantial, reflecting the high stakes of the sport. Each backup car represents a significant investment, mirroring the cost of the primary race car in terms of construction, maintenance, and transportation.

For top-tier teams, this is a manageable part of the budget, but for smaller teams, it’s a major financial strain. This disparity often influences team strategies and can impact overall competitiveness.

The investment extends beyond the car itself to include spare parts, dedicated crew time, and additional logistics. This financial perspective underscores the economic complexities of NASCAR racing, where financial muscle can be as crucial as driving skill.

Training and Preparation for Backup Drivers

Backup drivers in NASCAR occupy a unique and challenging role. Unlike primary drivers, who have consistent track time and team interaction, backup drivers must maintain peak performance readiness often with limited notice.

This requires rigorous physical training and mental preparation, ensuring they can step into high-pressure race situations seamlessly. Teams often simulate race conditions for backup drivers and involve them in strategic discussions to keep them engaged and informed.

The psychological aspect of being a backup driver is complex, balancing the readiness to perform with the uncertainty of participation. Their preparation is a testament to the professionalism and depth of talent within NASCAR teams.

Behind the Scenes: The Crew’s Role in Managing Backup Cars

The pit crew and technicians play a pivotal role in managing backup cars, a task that demands precision, expertise, and unwavering focus. These unsung heroes of NASCAR work tirelessly behind the scenes, ensuring that both the primary and backup cars are race-ready at all times.

This involves meticulous assembly, rigorous testing, and constant adjustments based on track conditions and driver feedback. The crew’s ability to quickly switch to the backup car in the event of a pre-race mishap is a testament to their skill and preparedness.

Their role extends beyond the mechanical, contributing to the team’s overall strategy and potential for success on race day.

Do NASCAR Teams Have Backup Drivers?

Yes, NASCAR teams do sometimes have backup drivers, but their function isn’t quite the same as for backup cars. Usually, backup drivers are picked by teams in advance of known periods where the primary driver might be unavailable for personal or other particular reasons.

While backup cars are brought to all race days — assuming the team has the backups in the first place — backup drivers are chosen more like substitute teachers, for the most part.

A good example of this was when Trevor Bayne was chosen by Joe Gibbs Racing in 2022 to be the backup driver for Kyle Busch. At the time, Busch and his wife were expecting their second child, and so it was known that  Busch would be out of action for some time. Injury is another situation in which a backup driver might be called in.

One instance this happened was when Tony Stewart was injured during the 2013 season, after which his team (Stewart-Haas Racing) chose Max Papis to replace him at the next race.


Backup cars in NASCAR show how much planning and hard work goes into the sport. Teams put a lot of effort and money into making sure these extra cars are ready just in case they’re needed. Backup drivers also have to be prepared to jump in at any moment.

The people working behind the scenes, like the pit crew, play a big part in making sure everything goes smoothly. This all shows that NASCAR is not just about the drivers, but also about teamwork and being ready for anything that might happen during a race.
