The car was designed by Pete Brock who later worked for Carol Shelby and designed the Shelby Daytona Coupe.

The TR 250K has a Triumph 2.5L six-cylinder and a modified TR4A chassis assembled in Triumph's Competitions Department workshop by 'Kas' Kastner who ran the Competitions team. Kastner also built the TR-4 for Bob Tullius' for his D Production titles in 1963-64. The body is a custom aluminum skin by Borth and Rose in Southern California.

The reason for the TR 250K's creation was to move Triumph to a new modern light weight aerodynamic car around their 2.5-litre straight six engine to compete with the Porsche 911. Triumph supplied some seed money for the project and the TR 250K competed at Sebring, but Triumph failed to follow up on the TR 250K. Triumph later failed as did most all the British Leyland companies.

The spoiler at the rear was cutting edge for the time as an electronically adjustable aerodynamic aid. Movable spoilers or aerodynamic aids were later band on racing cars. However fixed rear spoilers are used almost universally even on production road cars.
