IndyCar Sonsio Grand Prix

The Sonsio Grand Prix, previously known as the Grand Prix of Indianapolis, is a notable event in the IndyCar Series, held at the Indianapolis Motor Speedway Road Course in Speedway, Indiana.

The race debuted in 2014 and traditionally takes place in mid-May, two weeks before the iconic Indianapolis 500. This event includes support races from the Road to Indy series, such as Indy NXT, USF Pro 2000 Championship, and USF2000 Championship.

The race course is a modified layout of the circuit previously used for the Formula One United States Grand Prix and later for MotoGP. Initial sponsorship by Angie’s List led to the event being called the Angie’s List Grand Prix of Indianapolis from 2015 to 2016.

To avoid confusion with the former Formula One Grand Prix held at the same venue, the name was changed to the IndyCar Grand Prix in 2017. In 2024, it was rebranded as the Sonsio Grand Prix due to new sponsorship.

The origins of this event trace back to a 2012 suggestion by Boston Consulting Group to Hulman & Co., the then-owners of the Indianapolis Motor Speedway, to consider hosting an IndyCar race on the road course. After successful feasibility tests in 2013, the inaugural race was scheduled for May 2014.

The road course underwent significant modifications to enhance competitiveness and fan experience, including reworking specific segments and repaving the entire course. The updated course measures 2.439 miles and includes the “Snake Pit” infield complex.

Throughout its history, the Grand Prix has become an essential fixture in the IndyCar calendar, providing an exciting prelude to the Indianapolis 500 and attracting both racing fans and bettors. The Sonsio Grand Prix continues to grow in popularity, offering a unique and thrilling motorsport experience.
