Carlos Sainz at Renault (2017–2018)

Carlos Sainz's brief but impactful stint with the Renault F1 Team from late 2017 through 2018 represented a vital transitional period for both the ambitious Spanish driver and the French manufacturer's re-established works effort.

How it began

Sainz's move to Renault was a significant shift, orchestrated mid-season in 2017. Having spent his formative years in Formula 1 with Carlos Sainz at Toro Rosso (2015–2016), he was a Red Bull junior, but opportunities at the senior team were not immediately available. Renault, having returned as a full works entry in 2016, sought to accelerate its progress up the Constructors' Championship. The opportunity arose for Sainz to join Renault for the final four races of the 2017 season, replacing Jolyon Palmer, as part of a complex engine deal that also saw Toro Rosso switch to Honda power. This early integration allowed Sainz to familiarise himself with the team and its RS17 challenger ahead of a full campaign in 2018, signaling Renault's clear intent to strengthen its driver lineup with proven talent.

The partnership's character

Sainz quickly established himself as a consistent and reliable points scorer for Renault. His arrival brought a fresh dynamic alongside the experienced Nico Hülkenberg. Sainz's driving style, characterized by his smooth yet aggressive approach, adapted well to the Renault chassis, which often favored a stable front end. He demonstrated strong race craft and an ability to extract performance even when the car was not at its absolute peak. The partnership was one of mutual benefit: Renault gained a driver who could consistently deliver results and provide valuable technical feedback, while Sainz secured a works drive, a clear step up from a satellite team, allowing him to further hone his skills and prove his mettle in a more competitive environment. His performance helped solidify Renault's position as a midfield leader, pushing them towards their goal of challenging the top teams.

Key chapter in the seasons

His debut at the 2017 United States Grand Prix was particularly impressive, securing a seventh-place finish immediately. This strong start set the tone for his full 2018 season. Throughout 2018, Sainz was a regular presence in the points, often battling fiercely in the competitive midfield. He frequently matched or outscored Hülkenberg, demonstrating his pace and consistency. A standout performance came at the 2018 Azerbaijan Grand Prix, where he finished fifth, showcasing his ability to capitalize on chaotic race conditions. While no podiums were achieved during this period, Sainz's consistent top-10 finishes were crucial in Renault securing fourth place in the Constructors' Championship that year. His contributions were vital in developing the RS18 and laying groundwork for future improvements. However, with Daniel Ricciardo's unexpected move to Renault for 2019, Sainz's future with the team became uncertain, leading to his eventual switch to Carlos Sainz at McLaren (2019–2020).

The legacy

Carlos Sainz's time at Renault, though brief, was a significant chapter in his career, serving as a springboard to higher aspirations. It validated his talent as a consistent, front-running midfield driver capable of leading a works team's charge. For Renault, Sainz's tenure was instrumental in their rebuild, providing the consistent points and development feedback needed to establish themselves as a serious contender in the midfield, setting the stage for their continued evolution towards eventually becoming Alpine. This period demonstrated Sainz's adaptability and determination, qualities that would later see him progress to Carlos Sainz at Ferrari (2021–2024) and become a Grand Prix winner.
