Rear Impact Structure Test

In Simple Terms

F1 cars must have a rear bumper that can safely absorb impacts. The test simulates a 50kg object hitting the car at 10 meters per second, and the car's structure must slow down the impact gradually without exceeding 25g of force. This protects drivers and other cars in collisions.

• A 50kg striking object must hit the rear at minimum 10m/s to test impact absorption
• The car's deceleration cannot exceed 25g (gravitational force) during the impact
• The deceleration profile follows a formula (15+26.5X) with a small allowance above limits for longer impacts
• This safety structure protects the driver and fuel tank from rear-end collisions
