Robert Bosch plans to increase investment in its new drivetrain components plant in Vietnam to US$133m by 2015 from the current $73m. 

The Gasoline Systems plant in the southern province of Dong Nai, which opened earlier this year, makes push belts for continuously variable transmissions (CVT). 

Production capacity at the plant will double over the next four years, from 1.6m units to 3.2m units per year. 

Vo Quang Hue, managing director of Robert Bosch Vietnam Company, said the additional investment reflects “rising demand for these products across Asia”.
