According to a report from Reuters, Mexican auto part factories are likely to post record output in 2015, growing, in value terms, by 5% from the $82 billion produced last year, a top industry leader said in February.

The auto industry is a major export earner for Mexico, and accounts for a large part of its manufacturing base.

"The major driver [for growth in 2015] is the dynamism of the U.S. auto industry," said Oscar Albin, head of Mexico's national auto parts industry association, INA.
