I follow some auto racing at a tertiary level. I do not watch every race. I vaguely follow reporting on F1 and some of the various GT classifications. The big race I try to watch every year though is what I think of as the second toughest (maybe third toughest) auto race all year. The 24 Hours of Le Mans.
The LMP1 prototypes are these fantastic vehicles with all sorts of interesting regulations put upon them which require amazing innovations. Essentially in the most recent races the cars have this category have been limited by total amount of energy they are allowed to use to complete each lap which is regulated by how much fuel they can have on board and how much energy they are allowed to recapture into hybrid systems and use throughout a lap.
