How Fast Is a NASCAR Racecar?

In NASCAR races, weight and speed are enemies, yet friends!

It’s because a car with good weight distribution can get more downforce, which means better speed at corners

That leads to the most important question: How much does a NASCAR car weigh so that the car can land exactly on the “enemy” and “friend” border?

How much a NASCAR Cup car weighs

According to the NASCAR rule book, a NASCAR Sprint Cup car must weigh at least 3,300 pounds (1496kg) without fuel or driver

NASCAR assumes that all drivers are 180 pounds

So, every 10 pounds under that number means a driver must add 10 pounds to the car to get back up to 180 pounds

He must add 50 lbs to his car so that it weighs 3305 lbs

In 2013, the NASCAR rule book did not apply weight penalty if drivers’ weight dropped under 140 lbs

For that reason, Danica Patrick, a female racer, who only weighed 110 lbs at that time, only had to add 40 lbs of extra weight, not 70!

Fuel is another factor as the number 3,300 lbs only apply to a car without fuel

A gallon of racing fuel weighs approximately 6 lbs

The maximum fuel capacity for Sprint Cup races is 22 gallons

Do some maths, and we have the maximum fuel weight of a NASCAR car – 132 lbs

That brings the total weight of a typical NASCAR Cup car up to 3,612 lbs (3,300+180+132), where driver and fuel weight are already taken into account

How much a NASCAR tire and wheel weigh

A NASCAR tire (18”) itself weighs about 24 lbs, and a wheel weighs 27 lbs

How much the engine weighs in a NASCAR car

NASCAR Sprint Cup cars use 358 cubic inches (59-liter) displacement V8 engines, which produce about 700 to 800 horsepower

These engines weigh around 575 lb or 260 kg (without oil), that’s more than 17% of the car’s weight

NASCAR weight distribution – How important is it?

Weight balance is an essential part of setting up a race car

You need to have the correct weight balance so that the car handles well while cornering

On an oval NASCAR race, the weight can be distributed more on the left side

This is because on an oval track, all cars only turn left

In this case, left-side weight distribution allows you to get more speed through the corners

On a road course, the weight distribution is closer to 50/50, because cars drive both left and right turns

That’s about left and right weight distribution, how about front and rear?

Cars racing on oval tracks usually have a front bias of around 52 percent for better grip on the front tires

On the other hand, cars racing on road course tracks prefer more weight on the rear, allowing more braking power and better acceleration

This video below show how pit crews can use a track bar to adjust the weight distribution of a NASCAR

How much does a NASCAR truck weigh?

Unlike the NASCAR Sprint Cup and NASCAR Xfinity Series cars, the NASCAR Camping World Truck Series race trucks’ minimum weight is 3400 pounds without driver and fuel

Even though NASCAR trucks carry 100 lb of extra weight, their engines can still produce nearly as much horsepower as the other two Series

NASCAR CUP cars’ minimum weight is 3,300 pounds

While this may seem like a lot, it is actually quite light when you consider all the equipment that goes into a car and the safety features that NASCAR requires

In a NASCAR race, everything needs to be carefully calculated and monitored, from the driver’s surroundings when another driver is closing in, to the car’s total weight

Drivers and their teams must meticulously calculate various factors for the best possible outcome, including the weight of their vehicle

NASCAR vehicles must meet specific weight requirements to pass inspection, such as a minimum of 3,300 pounds without drivers and fuel

The tires and wheels on the vehicle contribute an additional 51 pounds, and all four tires add 204 pounds in addition to the fuel

Weight plays an important role in achieving maximum speed and optimal performance, so drivers and their team work hard to manage the car’s weight as much as possible

While there are several things each team can do to minimize the car’s weight, NASCAR has specific weight limits to create a standard

This article outlines average car weight based on these standards and how drivers work to minimize their car’s weight, so continue reading to learn more!

What Does A NASCAR Car Weigh?

In the NASCAR Sprint Cup and NASCAR Xfinity Series, cars must meet specific weight requirements

Each NASCAR vehicle must meet two weight requirements: the first weight without the driver or fuel and the racing weight with the driver and fuel

Before adding the driver and fuel, the car must weigh a minimum of 3,300 pounds

After adding the driver and a full fuel tank, the vehicle must weigh at least 3,400 pounds

The weight requirements vary based on the series, as the NASCAR rule book has different rules for each series

In this series, each race truck has a minimum weight of 3,400 pounds without its driver and fuel

The tires and wheels on the vehicle contribute to the car’s overall weight

Given the importance of weight in races such as these, every pound counts

On average, an 18-inch NASCAR tire weighs about 24 pounds, while the wheel weighs approximately 27 pounds

All four tires add an extra 204 pounds to the vehicle’s weight

The post-inspection weight is based on an average driver weighing 180 and 189 pounds

So, to make up for this difference, NASCAR developed a sliding scale that takes the car’s weight into account

Since implementing this sliding scale, NASCAR has deviated from the 3,300-pound weight standard for drivers

If the driver weighs less than 180 pounds, they must add 10 pounds to the car to increase their weight

For instance, if the driver weighs 135 pounds, they’d have to add 50 pounds to their vehicle to meet the weight requirement

Prior to 2013, NASCAR’s weight rules offered exemptions for drivers weighing less than 140

Since this gave drivers weighing less an advantage over their competitors, NASCAR started using its sliding scale in 2015

Obviously, fuel is an essential piece of the weight puzzle, as these cars can’t go anywhere without it

A typical gallon of racing fuel weighs approximately six pounds, so with a full tank, fuel adds about 120 pounds to the car’s weight

As the race progresses, drivers may push their car to its limits as they attempt to race on low fuel

When they stop for fuel, the pit crew may not add a full tank, as this weighs the car down as the driver whizzes through the final laps

Why Is Weight Important For NASCAR?

Weight and speed are mortal enemies in a NASCAR weight

The more weight the car carries, the harder it’ll need to work to achieve top speeds

So, for the best performance, NASCAR drivers and their teams do their best to manage the weight of the vehicle

They begin fighting for first place while running low on fuel, making it dicey for the drivers as the race closes

You’ll usually see fuel-only pit stops at the end of the race

They stop for enough fuel to power through the race but nothing else, as their tires have enough tread to see them through

The Importance Of Weight Distribution

When designing NASCAR race cars, weight distribution was an integral consideration

Without the right weight balance, the car won’t handle well during corners

So, to aid in the races, NASCAR vehicles feature a specific weight distribution

With an oval NASCAR track, cars may have up to a 58% weight bias on the left side

This works because the cars only turn left on these tracks, so the more heavily weighted left side enables more speed through the corners

Since these tracks feature left and right turns, having a noticeable weight bias could affect the vehicle’s handling and performance

However, vehicles may feature a slight weight bias based on the quantity of left or right turns throughout the race

Aside from weight distribution from left to right, it’s also important from front to back

Generally, cars in NASCAR races on oval tracks have a slight front bias of approximately 52%

Conversely, cars racing on road courses usually feature a weight bias on the rear of the car

How Do NASCAR Drivers Adjust Weight Distribution?

Generally, the pit crews of each driver handle the weight distribution adjustments

They use a metal bar with multiple bends, known as a track bar, to adjust the car’s weight distribution as needed

In some cases, drivers adjust their car’s weight distribution themselves

According to the NASCAR regulations the NASCAR Cup Series racecar must weigh 3300 lbs at the minimum without the fuel or the driver

Adding the weight of the driver and fuel can bring the car’s weight to over 3500 lb

Read on as we break down the weight of the different NASCAR series cars and even talk about how weight distribution affects the performance of the racecar

How Much Do NASCAR Racecars Weigh?

Nascar has three different main series that all have different regulations for cars

NASCAR Cup Series

The NASCAR Cup Series is the top racing series for NASCAR (National Association for Stock Car Auto Racing)

According to the NASCAR rules, the minimum weight of the NASCAR racecar must be 3300 lbs (1500 kg)

This does not include the weight of the driver or the fuel

However, NASCAR also has strict rules concerning the weight of the driver

According to the rulebook, the minimum weight allotted to the drivers is 180 lbs

If a driver is below this weight, they have to add weight to their car

For example, if a driver weighs 160 lbs, they have to add 20 lbs to their car to make sure that the 180 lb requirement is fulfilled

However, this rule is only imposed until 140 lbs, after which a driver need not add more weight

Danica Patrick, a female driver who weighed only 110 pounds, did not have to add 70 lbs to her car and instead added only 40 lbs

Fuel also contributes to the weight of the NASCAR Cup racecar

Although the 3300 lb minimum weight does not include fuel, adding the fuel drastically increases the weight of the car

Cup racecars have a fuel capacity of around 22 gallons meaning that there are 132 pounds of fuel in the car

With the added weight of the fuel and the driver, the car weighs around 3600 lbs or 1630 kg!

NASCAR Xfinity Series

The NASCAR Xfinity Series is the second level of the NASCAR racing series2 and is considered a proving ground for the drivers who want to compete in the Cup Series

The cars in the Xfinity series have some differences when compared to the Cup series

The Xfinity series car is lighter than the Cup series and generally weighs 100 lbs less than the Cup series car

The minimum weight for the Xfinity series car is 3200 lbs (1450 kg), excluding the weight of the driver and the fuel

According to regulations, the car has to weigh over 3400 lbs (1540 kg) when the weight of the fuel and driver is included

NASCAR Camping World Truck Series

The Camping World Truck Series is the third tier of the NASCAR series and involves racing pickup trucks across the tracks

These trucks have a different body style than the cars in the other two series and are heavier than the cars in the Xfinity and Cup series

The trucks tend to weigh 100 lbs more than the cars in the Cup series and have a weight of around 3400 lbs (1540 kg) without the weight of the fuel and the driver

Importance of Weight Distribution in Racing

Weight is an important factor when it comes to the speed of the car

The heavier the car, the longer it will take to accelerate to top speed (and the more fuel it will use! )

However, the distribution of that weight can also influence the car’s performance on the track

Manufacturers of NASCAR racecars consider weight distribution to optimize the car’s performance and use the (quite significant) weight to their advantage

As weight distribution can affect the car’s handling, especially in corners, different distributions may be used for different tracks

Oval tracks only consist of left turns

If the NASCAR race is on an oval track, teams may distribute the weight more on the left side (up to a 58% bias) so that the driver can maintain high speed in the corners

For tracks that have both left and right turns, the weight distribution will be closer to 50/50

Weight distribution towards the front or back can also affect the car’s performance

Cars may have more weight in the front for better grip on the front tires

On road tracks, cars prefer having a weight bias towards the rear of the car

Comparison of NASCAR and Formula 1 Cars

NASCAR and Formula1 are the top auto-racing events around the world

Although the concept for both events is similar, the cars featured in the races are different in almost every way, from their designs to their engines and even their tires

The Formula 1 cars are smaller than the NASCAR ones and are designed for aerodynamics and maximum downforce

In comparison, the NASCAR cars are bulkier and square, suited to the rules of NASCAR racing

Moreover, a NASCAR Cup racecar weighs 3300 lbs

This is double the weight of a Formula 1 car that weighs approximately 1500 lbs

Apart from the way they look, a major difference between the two cars is the type of engine they use

A NASCAR Cup racecar uses 587L V-8 engines

On the other hand, a Formula 1 racecar uses a 16L V6 hybrid turbocharged engine that produces around 875-1000 horsepower

The Formula 1 car is designed to be lightweight and aerodynamic to help it cut through the air and achieve high speeds, going as fast as 230 mph

In comparison, the NASCAR cars are heavier and slightly bulky while still going as fast as 200 mph

With only a 30 mph difference in their top speeds, both Formula 1 and NASCAR are high-speed and exhilarating events that car enthusiasts from around the world enjoy

Q: What Is the Top Speed of a NASCAR Car?

NASCAR racecars have top speeds of up to 200 mph

These racecars feature V-8 engines and take 34 seconds to go from 0 to 60 mph

The weight of the vehicles means that NASCAR cars are slower than Formula 1 cars

All NASCAR car engines are not the same

All NASCAR car engines are not the same

The engines are similar and need the same specifications and standards; however, each manufacturer can design and modify them differently

Q: Who Is the Highest Paid NASCAR Driver?

Kyle Busch is the highest-paying NASCAR driver as of 2021

The minimum weight of the NASCAR Cup racecar is 3300 lbs without the driver’s and fuel’s weight

The minimum weight for the Xfinity series is 100 pounds less at 3200 pounds, whereas the Truck series is generally 100 to 200 pounds heavier than the Cup racecar

The weight of the racecar affects car acceleration as well as its handling

So, keep your car light and distribute weight smartly if you want those extra miles!
