The open cockpit of IndyCar makes it more dangerous in high speed crashes where despite state of the art helmets there is no roll cage. The car is also smaller means there is simply less of it to absorb impact when a crash happens than a NASCAR.

Racing Strategies: NASCAR Vs. IndyCar.

As mentioned below NASCAR racing has a focus, although shifting, on oval tracks with some Road tracks for many reasons.

IndyCar focuses, now, on Road tracks with some ovals. This means that although there are many similar skills and strategies these two types of tracks share, there are some that are more relevant on each.

Pack Racing and Drafting: Oval racing, in NASCAR, features a lot of Pack racing and drafting strategies. In indy car being too close to the car in front will cause overheating issues over time. Drafting is used to slingshot, not to burn up laps.

Push to pass: This feature, in Formula 1 as well, Allows drivers a 10 use power boost to help with overtaking. Nascar doesn’t focus on technology in the drivers hands as much as open wheel racing

Are Pit Stops the Same in NASCAR and Indycar?

In NASCAR, only six mechanics are allowed to work on the car during a pit stop. When the cars stop for four new tires and fuel, the stop last for between 12 and 16 seconds.Opens in a new tab. This time can be just five to seven seconds when only two tires and fuel are needed.

The pit crew team features one jackman, who lifts the car. There are also two tire changers, who have to unscrew the five lug nuts. There is a gas man, who puts fuel into the car, and two tire carriers.

In IndyCar, the same amount of six mechanics are allowed to work on the car during the stops. A mechanic at the rear of the car first inserts an air hose to active the car’s built-in pneumatic jacks, which lift the car. The four tire changers then take off the old tires and place the new ones on, as well as adjusting the angles on the front wing and removing any debris.

The gas man fills fuel into the car throughout the stop. Before the car leaves the pit lane it is also sprayed with water, which dilutes the fuel to ensure that the car doesn’t catch fire during the rest of the race.

Are IndyCar and NASCAR Made of the Same Materials?

As we mentioned above IndyCar and Nascar are very different cars. Indy cars weigh less than half the weight of a NASCAR race car and although some of this is due to size, it is also the construction materials that reduce the weight of an IndyCar.

IndyCar’s are constructed with a carbon fibre and kevlar chassis, where NASCARs, staying true to stock roots, are constructed of steel. Also the V8 engine in a NASCAR weighs considerably more than the V6 of an IndyCar.

What is NASCAR and IndyCar’s Biggest Race?

The NASCAR Cup Series started in 1949, and it was Strictly Stock, meaning that unmodified production cars had to be used. The first season featured just eight races, with seven on dirt ovals and one on the Daytona Beach street course. NASCAR’s most famous and prestigious race is the Daytona 500.

The race is 500 miles long, and it is raced over 200 laps of the Daytona International Speedway in Florida. The first edition of the Daytona 500 was run in 1959, and it was won by Lee Petty. Petty won the famous race seven times in his career. It is also known as “The Great American Race” and the “Super Bowl of Stock Car Racing”.

The NTT IndyCar Series, in its current guise, has been run since 1996. It was founded as the Indy Racing League, as a rival to the CART series which ceased to exist in 2003. The first season of IndyCar only featured three races, which due to the lack of a tiebreak rule meant that the title was shared between two drivers, Buzz Calkins and Scott Sharp.

The third and final race of the first season was the Indy 500, which is IndyCar’s most famous race, and their equivalent of the Daytona 500. The first IndyCar Series edition of the Indy 500 was the 80th overall Indy 500.

The Indy 500 was established before the IndyCar Series. The Indy 500 is a 500-mile race held over 200 laps of the Indianapolis Motor Speedway in Indiana.

Do NASCAR and Indycar Use the Same Tracks?

The IndyCar Series races on ovals, road courses and street courses. Traditionally, IndyCar raced the majority of its races on ovals, but in recent years the majority of races are held on street and road courses. The 2022 IndyCar Series schedule features just three oval circuits, one of which is the Indy 500 at the Indianapolis Motor Speedway.

The Series also race on the Indianapolis Motor Speedway Road Course, which was previously used by Formula One. IndyCar’s also race on street circuits due to the cars’ relatively small size. The street races include the season-opening Grand Prix of St. Petersburg.

16 of the 17 races are held in different states, with California being the only state with two races, at Laguna Seca and the Long Beach Street circuit. Other than the USA, IndyCar has hosted races in Canada, Japan, Australia and Brazil. IndyCar can race on street and road circuits in rain, but not the ovals.

NASCAR uses ovals, as well as road courses. However, they no longer have any street races due to the size of the cars. The competitive season opens with the Daytona 500, which is held on a tri-oval. The majority of the NASCAR Cup Series races are held on ovals, but they also use world-class road circuits such as the Circuit of the Americas, which is also currently used by Formula One.

The 2022 schedule also features a dirt race at Bristol Motor Speedway. NASCAR doesn’t race during rainOpens in a new tab. on the ovals, but they have raced in rain on the road courses.


We have the main differences highlighted between NASCAR and IndyCar above, Indy cars are a lighter, smaller open wheeled form of racing while NASCAR bases its sell of commercially available versions of manufactured cars and the differences don;t stop there:

The history of racing for racings sake of IndyCar, to the flying down a background with bottles of Moonshine of NASCAR. The speeds they can achieve, how much they crash and hit each other, and the dangers, or chance of danger in each sport is very different.

It might be easier to list what NASCAR and IndyCar have in common, which is 4 wheels, a steering wheelOpens in a new tab. and a driver, but, with the exception of the driver on occasion….even these are different.

One thing we didn’t mentioned, and probably cos you can work it out on your own. IndyCar and NASCAR…. well they look very different as well .
