Endurance elements meaning one tank of fuel for the entire race and limited sets of tires.I've seen more RACING at the 24h LM (esp. GTE classes) than in 1:20 of a F1 "race". So it's not the "endurance elements" (which ones BTW?).
Which is kind of ironic because in endurance racing refueling is allowed and if i'm not mistaken they can use all the tires in the world.
So yeah you're right, i should call it "cost cutting elements" or "efficiency elements". By call it endurance elements i'm insulting the amazing world of endurance racing.
