The Aston Martin AMR23 is a Formula One racing car designed and developed by the Aston Martin F1 team that competed in the 2023 Formula One World Championship. It is the third Formula One car entered by Aston Martin in the 21st century, and was driven by Lance Stroll and Fernando Alonso. Aston Martin reserve driver Felipe Drugovich temporarily replaced Stroll for all three days of the pre-season test in Bahrain, after the latter had a cycling incident that forced him to withdraw from the test. An immediate improvement on the AMR22, the AMR23 scored six podiums throughout the first half of the season, all through new Aston Martin signing Alonso. However, its performance began to deteriorate as the season went on, and Aston Martin would score no further podiums, bar two at the Dutch and São Paulo Grands Prix; its highest Grand Prix finish was three second places at the Monaco, Canadian and Dutch Grands Prix.
