British Sprint Championship 1975
The top six runners were much as they had been in 1974, except that John Ravenscroft was rarely seen and his place at the top table was taken by David Franklin and his nippy little Ensign. There were few new cars in the single seater classes as Bob Rose retained the McLaren M14D, Dave Harris his M10B/M14D and Johnty Williamson his Surtees. Among the smaller cars, David Render now had a 2-litre BDA for his Brabham BT35 but Rob Turnbull was still making do with 1600cc, as was Franklin in his Holbay-propelled Ensign.
Harris was completely on top in 1975, winning four events and finishing second in three more. Franklin won two but the Ensign was underpowered on some tracks, so was nearly caught for second in the title race by the consistent Rose. Hillclimbers again stepped in to win some events, Alister Douglas-Osborn winning at Curborough and Wellesbourne in October in his Pilbeam-Brabham R15, and Tony Griffiths again winning Weston in his ex-F1 Brabham BT33.

The points system for the championship remained the same as that used for the Hill Climb championship, awarding 10 points for the fastest time in the runoff, then 9 for second and on down to one point for tenth place (R.A.C Motor Sport Year Book 1973 p114 and 1976 p102 had no change between them). There was no longer an extra point awarded for beating the course's previous record time. With nine rounds taking place, the best seven results would count (ibid. p102).
