The two-time Formula One world champion is pursuing motor racing's Triple Crown - winning the Monaco Grand Prix, Le Mans and Indianapolis 500 - and ticked off the second of the three prizes in France.
Alonso shared the driving at Le Mans in the Toyota No8 and clearly demonstrated his skill and adaptability as a driver to the 256,900 spectators.
The Spanish driver, together with teammates Kazuki Nakajima of Japan and Sebastien Buemi of Switzerland, completed 388 laps in their Toyota hybrid vehicle, two more than Mike Conway, Kamui Kobayashi and Jose Maria Lopez in the other Toyota hybrid. Kobayashi qualified his auto in second place, exactly two minutes behind Nakajima, but it should be noted that Kobayashi still holds the all-time qualifying lap record from his 2017 run.
The result was never really in any doubt as the number 8 vehicle qualified on pole and led the race from the outset. The vehicle finished two laps behind, after a missed pit stop and minor penalty slowed down the sister auto.

But the Spaniard put in a remarkable stint during the night to reduce the deficit before Sebastien Buemi and Kazuki Nakajima did their bit to take back control of the race.
Nakajima - who had clinched the pole position - finished in the vehicle, the Japanese driver enjoying a moment of redemption after a technical problem cruelly denied him and Toyota victory in the closing stages two years ago. The rules are targeting a 3:20.00 lap around Circuit De La Sarthe, just six seconds slower than the current lap record, set by Kamui Kobayashi in 2017.
Toyota joins Mazda as the only Japanese manufacturers to win the event, when they did so back in 1991.
The auto will form the base of a racer, set to compete in the just-announced "hypercar" class of the FIA World Endurance Championship when new regulations take force in 2020.
Alonso's hopes had appeared to dim as the race entered the early hours, with his vehicle two minutes adrift of the sister Toyota after a stop-go penalty. "I don't think too much about how competitive we will be next year as it is impossible to predict: It is just about the sport". For much of the first six hours, the two Toyota LMP1 cars traded places and by the seventh hour of the race, the #7 vehicle had built a lead exceeding two minutes.
