When people think of car racing, the first thing that springs to mind is open-wheel racing. Because Formula One (F1) and IndyCar are included in this category, it is the pinnacle, the top rung of the whole shebang. The cars that race in this series have open-top automobiles with exposed wheels, as the name implies. While the open-wheel vehicles that compete in F1 and IndyCar may appear to be similar, the rules, guidelines, performance, and courses are all different.

F1 and IndyCar have a few fundamental variances, such as where the series races. IndyCar competes on both ovals and road tracks, but Formula One solely competes on road courses. Fuel type, location, top speed, aerodynamics, and budget are among the other distinctions. F1 vehicles run on high-octane gasoline, whilst IndyCars run on ethanol. F1 is a global championship with races held all over the world, whereas IndyCar races are primarily held in the United States. F1 vehicles generate significantly more downforce than IndyCars, allowing them to take corners faster but with lower top speeds. Finally, F1 teams have agreed to a $145 million budget cap in 2021, which will be reduced to $140 million in 2022 and $135 million in 2023-2025. IndyCar has a far smaller budget, ranging around $20 million.

Automobile de Sport

Although open-wheel racing is the most popular in the world, sports car racing comes in second. Because most manufacturers compete at the GT (Grand Touring) category with vehicles that look a lot like their high-performance supercars, this series is perhaps the one with the most clearly recognisable vehicles. This series features race vehicles such as the Lamborghini Huracan, Ferrari 488, Chevrolet Corvette, Nissan GT-R, and Porsche 911. The prototype class, which features non-production race vehicles with distinctive bodywork, high-performance engines, and outlandish designs, is also part of this series.

Races in this series can take anywhere from 2.5 to 24 hours. The 24 Hours of Daytona, the 24 Hours of Nurburgring, and the 24 Hours of Le Mans are among the most famous 24-hour races in the world. These races do, in fact, last 24 hours and are a rigorous test for both man and machine.

Touring Vehicle

Touring car racing is unfortunately only popular in Germany, the United Kingdom, the Netherlands, and Australia. The race vehicles are substantially modified road-going production automobiles that have been raced in this serious. Unlike the other race cars on this list, there is little that distinguishes the vehicles, resulting in fierce competition amongst drivers.

The Touring Car series includes races ranging from sprints (short distances) to endurances (long distances) (three hours or more). Supercars Championship (SC), World Touring Car Cup (WTCC), British Touring Car Championship (BTCC), and Deutsche Tourenwagen Masters are just a few of the Touring Car series to watch (DTM).

Automobile in Production

In the United States, this racing series is known as showroom stock, and it is one of the more affordable and straightforward ways for enthusiasts to get into racing. In this series, automobiles that have been barely modified or that have not been modified at all compete against cars that have been similarly outfitted. The suspension, tyres, wheels, aerodynamics, brakes, and performance vehicles that can be attached to the production-based road cars in this series are strictly limited. This is done to guarantee that racing vehicles are as comparable as possible in order to stay competitive. Professional and amateur drivers equally can participate in this series.
