UDT was United Dominions Trust, who among various holdings owned Laystall Engineering, the principal supplier of crankshafts to the British automotive and aviation industries.

This caused chief designer, Tony Robinson, to design his own monocoque car, patterned very closely after the Lotus 25, but with a thicker skin and running a BRM V8 rather than the typical Coventry Climax engine run in the Lotus 25.

This car is commonly referred to as the BRP-BRM and was raced by Innes Ireland and Trevor Taylor.

[1] As a constructor, BRP took part in 13 Grand Prix rounds, scoring a total of 11 championship points.

Instead, BRP was hired by Masten Gregory's stepfather George Bryant to build two cars for the 1965 Indianapolis 500, but enjoyed little success.
