For my first LaLeMans 2018 post, I’ve gone with the first winner of the 24 Hours of Le Mans and the most recent (until a little over 22 hours from now).
The first 24 Hours of Le Mans took place in 1923 and was won by the Chenard-Walcker driven by Andre Lagache and Rene Leonard. While they covered the most distance, they were not the winners by the Index of Efficiency. They did cover a total of 2,209.54 km over the 24 hours.
The most recent 24 Hours of Le Mans was of course last year in 2017 and was won by the Porsche 919 Hybrid driven by Timo Bernhard, Brendon Hartley, and Earl Bamber. They covered 5,001.84 km over the race time of 24 hours.
