Fernando Alonso's 2015 Formula 1 season was a stark departure from his previous competitive years, characterized by the profound technical challenges and underperformance of the newly reunited McLaren-Honda project.
Going in
Following a challenging Fernando Alonso — 2014 season with Ferrari, Fernando Alonso made the significant decision to return to McLaren, the team with which he had a tumultuous but ultimately competitive season in 2007. This move was predicated on the promise of a renewed partnership with Honda, marking the Japanese manufacturer's return to Formula 1 as a power unit supplier. High expectations surrounded this 'works' team collaboration, with many anticipating a rapid ascent back to championship contention, especially given the turbo-hybrid era's technical reset. Alonso himself spoke of a long-term project aimed at building a championship-winning car, a vision that resonated with his ambition for a third world title.
How it played out
The reality of the 2015 season quickly diverged from pre-season optimism. The Honda RA615H power unit proved to be severely underpowered and plagued by chronic reliability issues from the outset. Pre-season testing was marred by significant technical problems, culminating in a heavy crash for Alonso in Barcelona that forced him to miss the opening Australian Grand Prix. Once he returned for Malaysia, the pattern of struggle was set.
Throughout the season, the McLaren-Honda package consistently lacked pace, particularly on straights, and suffered from frequent mechanical failures. This led to a high number of grid penalties for exceeding power unit component allocations, pushing both Alonso and teammate Jenson Button to the back of the grid repeatedly. The team struggled to escape Q1 in qualifying sessions and retirements were a common occurrence. Alonso, known for his ability to extract every ounce of performance from a car, often managed to out-qualify and out-race Button when the machinery held together, but the overall performance deficit was too significant to overcome. The team finished ninth in the Constructors' Championship, accumulating a mere 27 points, with Alonso contributing 11 of those.
Defining moments
One of the most defining moments of Alonso's 2015 season occurred at the Japanese Grand Prix, Honda's home race. During the race, a frustrated Alonso transmitted the now-infamous radio message, "GP2 engine, GP2!" This candid outburst vividly encapsulated the team's profound power deficit and his personal exasperation with the situation. Another notable event was the Hungarian Grand Prix, a chaotic race that saw Alonso secure a surprising fifth-place finish. This result, achieved through a combination of strategic driving and attrition among competitors, stood as his best of the season and a rare highlight for the struggling team.
What it meant
The 2015 season marked the beginning of a challenging three-year period for Fernando Alonso and McLaren-Honda, a period that would severely test his patience and commitment to Formula 1. It showcased his unwavering resilience and ability to motivate a team despite a complete lack of competitive results, further solidifying his reputation as a driver who could extract the maximum from any machinery, regardless of its inherent limitations. The struggles of this year set the tone for continued difficulties in Fernando Alonso — 2016 season and Fernando Alonso — 2017 season, ultimately influencing his decision to pursue other racing ventures, including the Indy 500, and eventually take a sabbatical from Formula 1. It was a season that, while devoid of success, underscored Alonso's enduring competitive spirit in the face of adversity.
