Leading racing organization the Heart of Racing announced that Hannah Greenemeier will join Hannah Grisham behind the wheel of the #26 Aston Martin Vantage GT4 for the upcoming SRO Pirelli GT4 America campaign, building upon the experience that the team collected last year with their first ever all-female line up.

The Heart of Racing launched an all-female project in last year's Pirelli GT4 America's championship and, having received over 100 applications, selected 9 female drivers for a driver shootout. After a two-day selection, Hannah Grisham and Rianna O'Meara-Hunt were announced as the two winners and contested the full season of the SRO-promoted series.

Grisham would secure two pole positions and, with a breakthrough season finale, Grisham and O'Meara-Hunt took back to back victories at Indianapolis Motor Speedway in October, becoming the first all-female team to win in the series.

Now entering its second season, the project welcomes Hannah Greenemeier, who will team up with Hannah Grisham in the #26 Aston Martin in the AM class.

“Getting a call from the team to join the Heart of Racing for the 2024 season was probably the best day of my life so far,” said Greenemeier. “To be able to drive for a team that has had so much success means so much to me and my family. I’m looking forward to getting the season started with the team in April at Sonoma.

Greenemeier therefore moves from single seaters to GT4, having tested a variety of cars.

The Colorado-native made history when she became the first woman to win in the highly-competitive SKUSA X30 ProTour Championship in 2021, and established herself as one of the most promising karting drivers in the US.

She made her F4 US debut 2023, and immediately showed pace for the top-ten. In the second half of the season, she claimed her first points at New Jersey Motorsport Park and went on to score points in four consecutive races, including a sixth place as a personal best at VIRginia International Raceway.

"I know that I have a lot to learn about sports car racing, but I know that with the help of my co-driver, Hannah Grisham, and everyone else on the team that I will get up to speed quickly", Greenemeier continued. "I can’t thank Gabe, the Bernier family, Ian, Paul and everyone on the team for this incredible opportunity.”

Grisham - also a Shift Up Now athlete - proved to be one of the fastest drivers in the AM class last year and will be back for a second year in Pirelli GT4 America in 2024.

“I’m extremely excited for the opportunity to continue with the Heart of Racing for a second year in GT4 America,” said Grisham. “I am looking forward to this season with a year under my belt and a more solid foundation to stand on. Year number one has taken me to most of the tracks, helped me to understand my competition, and have a better grasp of our Aston Martin Vantage."

"My goal for this year is to have strong, consistent finishes and hopefully be in a spot towards the end of the year to fight for the championship. I think Hannah Greenemeier and I are capable of this and I’m eager to get to work with her in April at Sonoma.”

The season will get underway at Sonoma Raceway on April 5-7, for the first of seven double-header rounds.
