Today marks the 50th Anniversary of one of McLaren's greatest achievements. In 1974, they became the second manufacturer in history to win the Formula One World Championship and the Indianapolis 500 in the same year. Motorsport legends Emerson Fittpaldi won the F1 World Title in the McLaren M23, and Johnny Rutherford won the Indy 500 with the McLaren M16, two cars with very similar design concepts that stood the test of time.

To mark the occasion, Autosport's Chief Editor Kevin Turner made the trip out to Pembrey in North Wales to have the McLaren Heritage Program fire up both cars together for the first time, and on this edition of the Autosport Podcast, he and Dre Harrison chat about what made McLaren's double so special.

From the intertwined development path that both cars took, the dramatic rise of speeds in Indianapolis in the early 1970s, to how Fittipaldi triumphed in '74 as both he and Clay Regazzoni entered the final round of the Championship tied on points, something that's only happened twice in F1 history, Dre and Kev talk about the enduring legacy of McLaren's legendary double.
