F1's Secret Barcelona Shakedown: Unveiling New Regulations and Car Innovations

• The Barcelona Shakedown is a private, closed-door event where F1 teams test their new cars with no mileage limits, unlike promotional runs.
• It's the first opportunity for teams to run new cars in race conditions, validating key components, systems, and power units.
• Held at Circuit de Barcelona-Catalunya from January 26-30, each team can choose three days for testing, strategizing based on weather or parts availability.
• The primary focus is on functionality and reliability, not speed, with engineers checking cooling, electronics, software, and simulator data accuracy.
• The 2026 regulations will introduce shorter, narrower, lighter cars with active aero, replacing DRS, allowing drivers to use extra electrical energy for overtaking.
