Colin Strang was born in New Zealand and was sent to England for his education after which he returned to his native North Island, where he took up hill climbs and grass tracking on motorcycles. He returned to England permanently in 1934 and set up Strang Motors in Harrow.

Strang raced an Austin 7 and a Bugatti Type 37 prior to the war but without noted success. During the war, Colin served in the Royal Army Service Corps in Ceylon, after escaping from Singapore.

Colin was one of the first to present a complete car having built his Strang 500 in just four months. As was common at the time, he also gave assistance to Frank Bacon in the construction of his special.

Colin won at Prescott in May 1946 and then won the next six events: Shelsley in June, Prescott in July and August, Bo'ness in September, Prescott again and Crofton Hacket, an incredibly successful start. For 1948, he appeared at the "White Hart" meeting then won at Prescott in May and Shelsley in June before finally being beaten by Eric Brandon's Cooper at Prescott the following day. The Strang failed to finish at the Gransden Lodge race meeting on 13th July but turned the tables on Eric on the 20th. He continued to compete on the hills and, occasionally, circuits through the remainder of 1948 and '49 but now had to content himself with placings as quicker cars appeared, although he achieved one final win at Bo'ness in June '49. Inevitably, by the end of 1949, his car became outclassed and, after one race in a Kieft, Colin left motorsport.
