Drivetrain System International (abbreviated as DSI), and previously operating as BorgWarner Australia, BTR, and ION^[1] is an Australian drivetrain constructor and engineering consultancy based in Scoresby, Victoria.^[2] At its previous manufacturing facilities^[3] in Albury, New South Wales,^[4] it produced drivetrains for Ford, Maserati, Chrysler, Geely and SsangYong.^[5] The company has also produced gearboxes for the Mahindra Scorpio.^[6]

Drivetrain Systems International was formed following the purchase of the Lavington gearbox factory, built in 1971, from the ION Group in 2004. In 2007, the factory produced gearboxes for SsangYong, which became the DSI's largest customer following the cessation of Ford's patronage in 2011.^[6]

In 2009, the company entered bankruptcy protection, mostly due to the bankruptcy and halt of production of its main customer, SsangYong. An effect of this was the loss of 230 jobs at the Albury facilities, with 167 jobs remaining. The workers were eligible for the Australian Government's General Employees Entitlements and Redundancy Scheme.^[7] The same year, the company was purchased by Chinese car manufacturer Geely for over A$55 million.^[6]

Gearboxes designed by Drivetrain Systems International were manufactured in Geely factories in Hunan, Shandong and Chongqing.^[6]

Geely subsequently sold DSI to Chinese investment company Shuanglin in 2015 ^[8] who continue to manufacture the DSI designed products in Xiangtan, Jining and Ninghai.^[9]

In 2020, DSI's Australian operations relocated to a new facility in Scoresby to provide engineering services both within and outside of the automotive field.^[2]
