Toyota Deliberately Crashes GR Models to Ensure Perfect Performance
Toyota's rigorous GR testing methodology combines intensive track testing with precision manufacturing to create consistently high-performance vehicles. At their Gazoo Racing facility in Japan, development drivers including Toyota Chairman Akiyo Toyoda (racing alias "Morizo") deliberately push test vehicles to their limits until failure.

This destructive testing has led to critical improvements. For example, when Morizo rolled a GR Yaris due to a four-wheel drive system fault, engineers identified and fixed the software issue before it could affect production vehicles.

The GR factory employs a unique cell-based assembly process, more akin to motorsport operations than traditional production lines. This allows for rapid implementation of improvements while maintaining exceptional precision.

Key manufacturing features include:
- Ultra-tight tolerances far exceeding standard production cars
- Precise measurement of suspension mounting points
- Custom-matched subframes for each vehicle
- Steering wheel remains untouched until final alignment
- Usage of turntables to avoid premature steering forces
