Kenelm Edward Lee Guinness MBE was an Irish racing driver of the 1910s and 1920s mostly associated with Sunbeam racing cars. He set a new Land Speed Record in 1922.

Sunbeam Motor Car Company Limited was a British automobile manufacturer in operation between 1905 and 1934. Its works were at Moorfields in Blakenhall, a suburb of Wolverhampton in Staffordshire, now West Midlands. The Sunbeam name had originally been registered by John Marston in 1888 for his bicycle manufacturing business. Sunbeam motor car manufacture began in 1901. The motor business was sold to a newly incorporated Sunbeam Motor Car Company Limited in 1905 to separate it from Marston's pedal bicycle business; Sunbeam motorcycles were not made until 1912.
