From a recent Bloomberg report:
"Stronger demand for automobiles bolstered U.S. manufacturing, which grew in April at the fastest pace in almost a year, according to Institute for Supply Management. The group’s factory index climbed to 54.8 last month, the best reading since June.
Chrysler Group LLC, the biggest gainer of U.S. market share through April, said four plants will skip normally scheduled two-week midyear shutdowns to meet increased demand. Factories in Belvidere, Illinois; Toluca, Mexico; and Detroit, and a parts factory in Toledo, Ohio, will stay open, the company said May 2 in a statement on its website. Two more plants will shut for one week instead of two, according to Auburn Hills, Michigan-based Chrysler.
“We need to build a few more vehicles, so they’re staying open,” said Jodi Tinson, a company spokeswoman."
