Guy Martin and the Project 100 team have been developing a streamliner for the 2023 land speed record season to beat the current 376-mph land-speed record (from 2010), with the streamliner they call the 52 Express, at Bolivia’s Uyuni Salt Flat

Powered by a Rolls-Royce Gem-42 Turbine lifted from a Westland Lynx military helicopter, the 1,200-horsepower machine also benefits from aero-grade metal tubing.

The monocoque aluminum cockpit saves weight, and two parachutes help bring the streamliner to a halt.

On the first day of testing, which was the 17th of November 2021, Martin only executed sub-90-mph runs, with the team focusing on braking distances along with system and safety checks. The second test day upped the pace to 150 mph

In 2016, Guy Martin set a record at Bonneville for the Triumph company, setting a record of 274.2 mph which was the fastest any Triumph bike had gone.
