HANNAH GRISHAM & HANNAH GREENEMEIER Step Up to IMSA Pilot Challenge for 2026

December 12, 2025

• HANNAH GRISHAM and HANNAH GREENEMEIER are stepping up from Pirelli GT4 America to make their IMSA debut with The Heart of Racing in 2026, piloting the #26 Aston Martin Vantage GT4 in the competitive GS class – a move that shows the academy program is actually delivering on its promises to develop female talent.
• These two have the receipts to back up this promotion: six podium finishes together in GT4 America, including standout performances at Sebring and Road America, proving they can handle the pressure when it counts and showing they’re ready for the step up to longer IMSA format races.
• The duo will tackle iconic new venues like Daytona International Speedway for the season opener on January 23, joined by Aston Martin factory driver Mike David Ortmann for the four-hour endurance round – because apparently even proven female drivers still need a factory guy to legitimize the effort in some people’s eyes.
