The design team are all British.^[5] The machine was primarily designed and created by Alex Macfadzean, who holds the British motorcycle land speed record.^[6] Macfadzean had worked as crew member on Don Vesco's wheel-driven land speed record holding (as of 2014) automobile Turbinator in 2001.^[7][8]

The powerplant is a 1,000-horsepower (750 kW) Rolls-Royce Gem turboshaft engine, originally built for helicopter applications.^[1][9] The rear wheels are driven by dual Kevlar belts.^[2]

According to Bennetts and others, the rear tire may be constructed of polyurethane by a roller coaster wheel manufacturer.^[2][9]

Students at University of Derby have provided aerodynamic studies of the body and air intakes.^[5][6] They aim to create a design with coefficient of drag less than 0.121.^[1] As of June 2016 this task was adopted by Cranfield University.^{[citation needed]}

A second nearly identical streamliner, with a piston engine originally made for the BMW K1100 motorcycle, has been built for testing.^[10]
