During the 1970s and '80s many memorable rallysport events were captured on film for the Castrol archives.

Now these fantastic visual records enable us to wind back the years and relive some rarely-seen action from a great era.

Here we recall the memorable clash between Audi and Lancia on Corsica's notorious tarmac in the 1983 Tour de Corse.

'The Professionals' offers a fascinating comparison between the Ford Rally team at the 1978 Rally of 1000 Lakes and Jody Scheckter at the British F1 GP.

This is worth watching just for the sound of the fabulous Quattro and Tony Pond's dry humour while driving in the outclassed Celica!
