  • The Name of the Series


    NTT IndyCar Series logoThe IndyCar Series takes its name from its most iconic race: the Indy 500. The term became prominent in the 1960s and 1970s as the Indianapolis 500 gained importance. The first official use of the name dates back to 1979, when CART split from USAC and created the “CART Indy Car World Series,” where “Indy Car” was written as two separate words.

    The “Indy Car” name remained in use until 1996, when Tony George founded the Indy Racing League. At that time, CART lost its license to use the “Indy Car” name. As part of an agreement between CART and the Indianapolis Motor Speedway, the name “IndyCar” or “Indy Car” could not be used for six years.

    In 2003, this restriction expired, and the Indy Racing League was rebranded as the IndyCar Series, a trademark secured by IMS in 1992. The Indy Racing League name was gradually phased out, and in 2011, the parent organization officially became INDYCAR LLC.

    Before the adoption of the Indy Car name, the cars were referred to as Championship cars, later abbreviated to Champ Cars. CART used this name for its cars after losing the rights to “Indy Car,” and between 2003 and 2007, Champ Car was also the name of the series itself.


    The History of the IndyCar Series


    IndianapolisThe IndyCar Series boasts a rich history dating back to 1909. Over the years, the series has been governed by several organizations, starting with the AAA from 1909 to 1955. Today, it is overseen by INDYCAR LLC, the successor to the Indy Racing League (IRL).

    The series has undergone significant changes over the years. Its cars have seen numerous technological advancements, and the circuits have evolved dramatically. In its early days, races were held on wooden board tracks, dirt tracks, and even beaches. Since 1911, however, the Indianapolis Motor Speedway has been a mainstay on the calendar as a paved oval.

    In 1971, off-road racing was officially abandoned, and races have since been held only on paved ovals, permanent road courses, and street circuits. From 1996 to 2004, the Indy Racing League exclusively ran oval races, while Champ Car abandoned ovals entirely by 2007.

    A pivotal moment in the series' history was the "Open Wheel War." In 1996, Indianapolis Motor Speedway owner Tony George split from CART’s popular Indy Car World Series to create the Indy Racing League. From 1996 to 2007, the rivalry between the two series resulted in smaller fields and lower viewership.

    In 2008, the two series reunited, with the Indy Racing League incorporating key aspects of Champ Car (as CART was renamed in 2003). Despite the merger, the series is still working to regain the audience lost to competitors like NASCAR.

    In 2020, INDYCAR LLC was acquired by Penske Entertainment, owned by Team Penske founder Roger Penske.


    The Cars


    Scott McLaughlin, Indianapolis,All teams use the same race car chassis: the Dallara DW12, introduced in 2012, and fitted with a universal aero kit launched in 2018. Depending on the type of circuit, the cars weigh between 751 and 771 kilograms. This makes them heavier than Formula 1 cars but also more robust and cost-effective.

    Although all teams use the same chassis, the series is not a complete spec series. Teams are allowed to develop their own dampers, which leads to extensive development programs. Additionally, teams have some flexibility in choosing aerodynamic components.

    The cars are powered by 2.2L V6 hybrid turbo engines supplied by Honda and Chevrolet. Depending on the circuit, these engines produce between 650 and 700 horsepower, with an additional 150 horsepower available via the hybrid system during push-to-pass activation. The engines run on a blend of 85% ethanol and 15% gasoline.

    Participating drivers and teams


    IndianapolisIn 2025, 27 cars will compete full-time. However, this doesn’t necessarily mean there will be 27 full-time drivers, as some teams may assign multiple drivers to a single car over the course of the season. While the series is primarily based in the United States, it has a highly international field. In 2024, drivers from 16 different nationalities participated!

    The 27 full-time cars are fielded by 11 teams, most of which enter two or three cars each. Ten of these teams are part of the "IndyCar Charter" program, granting them automatic entry into all races except the Indy 500. Prema Racing is the only team not part of this program.

    In most races, 27 cars are allowed to participate. If a team enters an extra car, a pre-qualification session will be required, featuring drivers from Prema and any additional entries.

    For the Indianapolis 500, the field is capped at 33 cars. If more drivers enter, a special "Last Row Shootout" determines the final grid spots.


    Tracks


    Callum Ilott, Long BeachThe IndyCar Series races on three types of tracks: street circuits, permanent road courses, and ovals. Ovals are further divided into superspeedways and short ovals. The 2025 calendar consists of 17 races: 4 street circuits, 7 permanent road courses, and 6 oval races. This variety demands that IndyCar drivers be true all-rounders!

    In 2025, 16 of the 17 races will be held in the United States. The only exception is the Toronto race in Canada. Most races take place in the Midwest, in cities like Indianapolis, Milwaukee, and Detroit. California also features prominently with three races (Long Beach, Laguna Seca, and The Thermal Club).

    The most important race of the season is the Indianapolis 500, held every May. It is the largest single-day sporting event in the world! Another iconic race is the Long Beach Grand Prix, held on a street circuit.
