San Luis Potosi, Mexico - The world's largest carmaker, The General Motors Company, said on Thursday that it would build the new Chevrolet "Trax" vehicle and a new generation of pickups at plants in Mexico.

The Detroit-based company is investing $120 million in a plant in the state of San Luis Potosi to produce the SUV crossover, said GM Mexico president, Ernesto Hernandez.

GM will unveil the Trax at the Paris Motor Show in September before hitting the Mexican market in the fourth quarter, Hernandez added. A further $200 million will head to the Silao plant in Guanajuato, where work on a new generation of pickups will begin in 2013.

Hernandez said that the company expects the investments, which total $420 million, will create about 1,000 new jobs in Mexico.

GM announced in May that the Trax, which will be sold in 140 countries, but not the United States, would be built on the same underpinning platform as the Aveo and Sonic subcompact sedan.

The Sonic is sold in the US and Canadian markets while the Aveo sells to the rest of the world. No new details were given on price, weight, length, and fuel economy of the Trax.
