Difference Between Indy Car And F1?

Motorcar racing as a sport has gripped the imagination of fans for over 120 years. From a formal race run in 1894 between  Paris and Rouen in France, over a distance of 50 miles (80 km) at a spine-tingling speed of 10.2 mph (16.4 kph) to the modern era vehicles which run at 240mph (386km/h), the sense of competition remains.

IndyCar and Formula 1 racing is different.

1. The cars share very little technology, and each is designed for different circuit types.
2. F1 teams develop their cars, whereas a standard IndyCar is provided to each racing team.
3. The types of circuits are different.
4. The rules are different.

IndyCar runs on Ovals, road tracks, and street circuits, whereas F1 only runs on racing and street circuits. Although they may look the same, the cars are entirely different and use differing technologies.

The Differences Between Indy Car And F1

F1 and IndyCar racing are the two single-seater racing series that attract the most audiences.

They arose from very different circumstances, and although each series of racing cars look similar at a glance, they could not be more different.

The Differences Between IndyCar And F1

In this article, we will discuss the differences between each series.

Formula 1 Series History

Although Formula 1 can trace its roots back to the late 1800s, the first formula 1 race was run at the Silverstone Circuit in the United Kingdom in 1950. The sport has developed into a truly international competition with races being held.

IndyCar Series History

IndyCar traces its roots back to 1905 when the  American Automobile Association (AAA) racing Board announced that it would sanction the National Track Championship. It didn’t last long because, in 1906, the series was canceled.

The authorization was restored in 1908, and in 1911 they ran the first race at the Indianapolis speedway. The race was named the International 500-Mile Sweepstakes Race and ultimately became the Indianapolis 500 in the modern era.

Through the intervening years, which included the great depression, the second world war, the Korean and Vietnam wars, the series has evolved until it moved under the United States Auto Club (USAC).

IndyCar started racing under the banner of the Indy Racing League (IRL) in 1996.

The most significant disruption occurred in the 1970s when the series split due to friction between USAC and team bosses.

The owners of the teams created Championship Auto Racing Teams (CART), bringing most drivers across to the new association.

They ran the series under the CART umbrella until a further split happened, with the series moving into the Indy Racing League (IRL). The division held until 2008 when both series remerged and became known as IndyCar racing.

IndyCar racing is an American event, and races are only held on tracks situated in North America.

The Racing Cars Are Different

Although both series race single-seat, open cockpit racing cars with similar silhouettes, the vehicles are very different.

Formula1 Cars

Modern formula 1 cars are developed by  10 different manufacturers, who collectively race 20 vehicles, designing their chassis’, suspension, running gear,  electronics, aerodynamic designs, and body shells. The designs of all of these components have to follow guidelines and restrictions imposed by the FIA controlling body.

Four manufacturers provide engines as follows.

Team	Engine Supplier
AlphaTauri	Red Bull Racing
Alpine	Renault
Alfa Romeo	Ferrari
Aston Martin Aramco	Mercedes
Haas	Ferrari
Ferrari	Ferrari
McLaren	Mercedes
Mercedes	Mercedes
Red Bull Racing	Red Bull Racing
Williams	Mercedes

Formula 1 cars use complex aerodynamic systems, which contribute massively to the team’s relative competitiveness.

The cars use hybrid engines built around a 1.6l internal combustion engine.

The hybrid power plant is an electric motor powered by an energy storage device (battery). The battery is charged by energy captured from the braking system and the exhaust gasses. These engines produce just under 1,000 BHP.

Gearboxes must be semi-automatic and have eight forward and one reverse gear. The FIA rulings fix the gear ratios, and they must last for six consecutive events.

In an attempt to level each team’s investment, a cost cap of $140 million is imposed for the 2022 racing season.

Including the driver, F1 Cars must weigh a minimum of 795kg.

• The steering wheels used in F1 cars carry all instrumentation, communication, engine modes, gear change paddles. Brake balance and differential settings.
• Pirelli provides tires, and on race day, only three dry-weather compounds and two wet-weather compounds can be used by the teams.
• F1 car’s regular top speed is 205mph (330km/h), but in 2019 both Sebastian Vettel and Sergio Perez managed a top speed of 223.5mph (360km/h) on the Monza F1 circuit.
• Although F1 cars do have a lower top speed than IndyCars, they accelerate faster and have superior aerodynamics, allowing them to corner faster.

 An F1 car would complete a typical circuit faster than an IndyCar.

IndyCar Racers

The same chassis and aerodynamic kit are standardized across all IndyCar teams, and there are only two engine suppliers (Honda and Chevrolet).

The cost of IndyCar teams is  $5 to $30 million (including the cost of the car) per year (compared to $140 million) for an F1 team.

There are 11 teams and 29 drivers.

• The engines have a capacity of 2.2L and have 6 cylinders in a V-shape. The engines produce between 550bhp-700bhp depending on the amount of boost used.
• In the 2024 racing year, IndyCar will increase the size of the engine to 2.4L and will add a hybrid KERS component which will increase the BHP to 900.
• Six-speed, semi-automatic paddle shifts gearboxes are used.
• Firestone supplies Tires which include two dry weather compounds and one wet.
• IndyCars’ top speed on an oval circuit is 240mph (386km/h).
• IndyCars have faster acceleration and higher top speed than F1 cars; however, the straight-line speed advantage does not translate into better track times.

The Racetracks Are Different

The racetracks on which each series compete are very different.

Formula 1 Racetracks

In the 2022 racing year, F1 will race in 24 different circuits globally.

The shortest circuit is 1.9 miles long, and the longest racing circuits are 4.3 miles long.

The road surfaces of all F1 tracks are very well prepared, and even though several events are held as street circuits, the race tracks are prepared to a very high level.

IndyCar Circuits

IndyCar races on 16 different tracks, of which 15 are in America, and one is in Canada.

The races are held on three different track types.

1. Street Circuits (4)
2. Ovals (5)
3. Road Courses (7)

Date	Track	Place	Track type
27 February	Streets of St Petersburg	St Petersburg	Street circuit
20 March	Texas Motor Speedway	Texas	Oval
10 April.	Streets of Long Beach	Long Beach	Street circuit
1 May	Barber Motorsports Park	Alabama	Road-course
14 May	Indianapolis Motor Speedway	Indianapolis	Road-course
29 May	Indianapolis Motor Speedway	Indianapolis	Oval
5 June	Raceway at Bells Isle Park	Detroit	Street circuit
12 June	Road America	Wisconsin	Road-course
3 July	Mid-Ohio Sports Car Course	Ohio	Road-course
17 July	Streets of Toronto	Toronto	Street circuit
23 July	Iowa Speedway	Iowa	Oval
24 July	Iowa Speedway	Iowa	Oval
30 July	Indianapolis Motor Speedway	Indianapolis	Road-course
7 August	Streets of Nashville	Nashville	Street circuit
20 August	Worldwide Technology Raceway	Madison, Illinois	Oval
4 September	Portland International Raceway	Portland	Road-course
11 September	WeatherTech Raceway Laguna Seca	Monterey, California	Road-course

Tracks range in length from the shortest at 0.8 miles to the longest at 4 miles.

IndyCar tracks feature longer straight than F1 tracks, which is why such high speeds are possible.

Global TV Audiences

With each sport, the size of the TV audience is the most important number when it comes to the financial value of the series.

Formula 1 TV and Internet Audiences

In 2021 an average of 70.3 million viewers watched each Formula 1 race.

IndyCar TV And Internet Audiences

In 2021 an average of 1.58 million viewers watched IndyCar per race.

Conclusion

A simple comparison of Formula 1 and IndyCar is not fair to either sport. Each runs in very different ways with completely different cars; because F1 is an international sport run on 24 circuits globally, the awareness of the sport and the audience numbers are substantially higher.

The takeaway from this is that both sporting series provide compelling viewing to dedicated followers irrespective of the differences. The tracks and cars may be different, but the level of driver skills and the adrenaline-inducing action are the same.
