Popular and easy going son of Reg Parnell, Tim never quite managed to match the success of his father, however he had an enjoyable career in minor F1 and F2 races in the late fifties and early sixties.
He first got involved in motor sport working as a mechanic for his father and started racing in 1957 with Cooper-Climax 1100 Sports car.
Suitably encouraged by a sound Formula Junior season in 1960, Tim purchased a Lotus 18 in 1961, which he hauled to the far corners of the Continent in search of success.
Illness curtailed his 1962 campaign, but he returned in 1963, only for the sudden death of his father the following January to thrust him into the role of running Reg Parnell Racing Ltd with drivers Chris Armon, Mike Hailwood and Peter Revson.
The team ultimately became the BRM Junior Team and from 1966 to 1975 he was the BRM Team and Works Manager. He was a member of FOCA from 1969 to 1975 and a committee member of Society of Motor Manufacturers and RAC Safety.
He is now a pig farmer based near Derby and an active director of the British Racing Drivers' Club.
