General Motors will invest part of a $800 million small-car spending plan in upgrading its Mexican auto facilities, Bloomberg reports. GM has lagged its U.S. peers in Mexico – it was sixth in auto exports in August, Panjiva data shows, with Ford first and Fiat Chrysler fourth. Its Mexican exports have also been falling – it exported 35% less by value in August than a year earlier, with exports to the U.S. 20% lower. The new investments may face political risks – Ford has already been threatened by presidential candidate Donald Trump with tariffs on exports to the U.S.
