Renault Power Unit Struggle Years

Lore & Background

The MCL35 represented a substantial development over its predecessor, the MCL34, with a new design increasing aerodynamic efficiency and optimized for Renault engines. It debuted at the 2020 Austrian Grand Prix, driven by Carlos Sainz Jr. and Lando Norris. McLaren finished third in the Constructors' Championship for the first time since 2012, achieving podiums at the Austrian and Italian Grands Prix, three fastest laps, and a fastest lap at the Red Bull Ring (though not a track record). In 2021, the MCL35M was driven by Norris and Daniel Ricciardo, debuting at the Bahrain Grand Prix. It set two fastest laps, one pole position, and scored five podiums, including McLaren's first win since 2012 and first one-two finish since 2010 at the Italian Grand Prix. McLaren finished fourth in the Constructors' Championship.

In Their Own Story

The rain lashed down over the wet tarmac of Spa-Francorchamps in 2007, turning the track into a mirror. Inside the cockpit of the MP4-22, Fernando Alonso gripped the wheel, feeling the familiar surge of the Renault V8 as he navigated Eau Rouge. The engine roared with authority, a stark contrast to the silence of the struggling seasons that would follow years later. For a moment, the partnership was invincible, but as the car slid through the wet corners, the fragility of their dominance was palpable; one mechanical failure or one strategic error could shatter the dream.

The MCL35 featured a thinner nose, more complex bargeboard, slimmer sidepod profile, and redesigned brake ducts. The suspension geometry was redesigned to influence airflow over the bargeboards and floor. The car used a matte vinyl wrap instead of paint to lower weight. The MCL35M required chassis modifications to accommodate the Mercedes engine, subject to FIA inspection, but McLaren continued to design and manufacture their own gearbox.
