Introduction
The Proving Ground is a performance assessment facility for and research & development of riding vehicles on actual road and road safety facilities
- High-speed circuit on which various high-speed performances are assessed
- Universal Trak for various purposes
- Curve test road for steering performance test during a turning
- Straight-line track for quick-check and acceleration noise test and noise test area with ISO certification
- EMC test pad to assess electronic systems under a free electromagnetic state
- Low-friction track that reproduces frozen roads, hardened snow-covered roads, snow-covered roads and wet road to test ABS
- Skid pad to test tire viscosity and feature assessment
- Off-road test track to test durability of car frame and chassis parts
- Road safety features test ground to support new product development and assessment tests through testing with actual objects of road safety facilities ; guide sign facilities, skid-proof pavement, etc.
