I have collaborated with this company since 1979, years in which, with Fiat, we were the first in the world to start developing CVT (continuously variable transmission) with the innovative metal belt.
Fiat was also a shareholder of this company in the years when the product was in development, therefore
losing money and strangely quit the company a few months before the company started producing on a medium scale.
