Production of motor vehicles in the USA increased by 10.1% in July, compared with a rise in output of 0.4% for the rest of the manufacturing sector.

Daniel J Meckstroth, chief economist for the Manufacturers’ Alliance for Productivity and Innovation, said: “Although production was up in 15 of the 20 major manufacturing industries, the explosive growth in the motor vehicles and parts industry was striking.

“The impact of the motor vehicle production success rippled through the supply chain for glass, metals, textiles and leather.”
