If there's one part of this Fittipaldi interview you must watch, it's the Brazilian's description of the last race in his championship-winning season (1974). See it
from 2:10
. He claims it was the only race of his career when he couldn't sleep properly the night before and also describes an epic duel with Clay Regazzoni on his way to the title. Described as a "do or die" moment we've no reason to doubt him.
This McLaren video comes from the Festival of Speed, where it was celebrating four decades since Fittipaldi's F1 World Championship in an M23. This video is more about the driver than the car so see here for something extra on the McLaren. Back when an F1 car could last longer than a season the M23 achieved 16 victories across five years with 10 poles also. The list of drivers is fairly incredible: Fittipaldi, Hunt, Mass, Hailwood, Hulme.
To hear Fittipaldi's ongoing passion for this car is riveting. He talks of instant familiarity and the same sensations flowing back very quickly after so long. We'd assume he must have been fairly comfortable give the smoky start up the hill... Legend.
