Formula 1 teams are increasingly utilizing Testing of Previous Car (TPC) programs as a valuable training tool. These tests allow teams to use cars from the previous three seasons while adhering to strict FIA regulations and providing numerous benefits for both teams and drivers.

Key aspects of TPC programs:

• Teams must use cars from 2021-2023 (as of 2025)
• Original parts only, with limited exceptions
• 72-hour advance notice to FIA required
• Details must be shared with competitor teams

Benefits for teams and drivers:

• Driver preparation and evaluation
• Testing new team personnel
• Practice procedures and pit stops
• Early season fitness assessment
• Benchmark setting for young drivers

Notable TPC implementations:

• Haas: First-ever TPC event at Jerez with Bearman, Ocon, and Miyata
• Mercedes: Extensive testing with Kimi Antonelli for 2025 preparation
• Ferrari and RB: Utilizing Italian tracks for winter testing
• McLaren: Providing opportunities for IndyCar stars and simulator drivers
• Alpine: Regular young driver development program

The TPC program has become essential in the cost cap era, offering teams a structured way to develop talent and maintain operational excellence while working within Formula 1's restricted testing regulations. It serves as a crucial platform for driver development and team preparation, particularly during the off-season.
