Mr. Sawai determined that if he could increase the decay rate of these vibrations inside of the structure, he could improve many elements of the vehicle. It took him only one year to take the concept of chassis damping from an idea into an actual working prototype.

Following a half year of testing, the first application of the PD came about in 2001 on the limited Toyota Crown Athlete VX with only 300 produced for the Japanese domestic market.

In 2004 another Japanese manufacturer bought into the performance damping concept with the introduction of the limited edition Subaru - S204. This proliferation of Yamaha technology in the automotive sector gained wide attention within the industry earning Yamaha several prestigious engineering awards in 2006 including
