Production of transmissions at Mazda's Hofu plant in Yamaguchi, Japan, will be boosted from the current output of 750,000 gearboxes per year to 1,140,000, and improvements to the factory will be complete by July 2014.
A new plant is also to be constructed in Thailand, coming online around the middle of 2015 and planned to produce around 400,000 transmissions per year.
Both the auto (Skyactiv-Drive) and manual (Skyactiv-MT) Skyactiv transmissions are a core piece of Mazda's Skyactiv technology suite, helping to improve fuel consumption by reducing internal mechanical drag in the driveline.
They also weigh less than traditional transmissions, which benefits fuel economy further.
In the case of the Skyactiv-Drive automatic, the torque converter's lock-up characteristics have been changed to favour earlier lock-up, thus delivering more power to the wheels and wasting less energy.
