Autosport takes on the challenge of picking the greatest competition car of all time in the final episode of the Autosport 70 podcast series. The first issue of Autosport magazine appeared on 25 August 1950 and as part of our celebrations this year we have selected the greatest machines from each of the major international categories. Our panel of experts debated the most successful and important grand prix cars, sportscars, rally machines, touring cars, Indycars and junior single-seaters in the previous episodes. The winner from each episode progressed to the grand finale, which also includes some wildcard entries.
