Fernando Alonso's 2015 Belgian Grand Prix performance at the iconic Circuit de Spa-Francorchamps was a testament to McLaren's ongoing struggles with the Honda power unit, as he converted a back-of-the-grid start into a 13th-place finish. Starting from 20th position, Alonso navigated the challenging 43-lap race, completing 42 laps and crossing the line a lap down on race winner Lewis Hamilton. Despite the overall team performance, Alonso demonstrated flashes of his characteristic pace, evidenced by his fifth-ranked fastest lap of the race, a 1:53.692, set on lap 34.
