With concepts taken from team Swinburne’s two previous dedicated electric vehicles – ts_12 and ts_13, the ts_14 was designed with a major focus on reducing weight and increasing reliability. The ts_14 is a comfortable all-round performer boasting a well-refined dynamics package that has been optimized to take advantage of the grip available at the front and rear without carrying over ts_13’s full aerodynamics package.

Major design changes included a 1:1 rear drivetrain package with independently controlled electronic differential, full composite monocoque, 10inch wheels, carbon fiber composite undertray and an in-house accumulator management system. While ts_14 lacked in low-end torque due to the simplification of its driveline, many found its presence on track surreal because of its complete silence – a side effect of no intermediate transmission.
