McLaren's MCL35: A competitive return to form with Renault power, later upgraded with Mercedes engines.
The McLaren MCL35 is a Formula One car designed under James Key and constructed by McLaren to compete in the Formula One World Championship. It was originally intended for the 2020 season only, but due to COVID-19 disruptions, its lifespan extended into 2021. An upgraded version, the MCL35M, was produced for 2021 as McLaren returned to Mercedes engines.

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, two 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 one fastest lap, one pole position, and scored four 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.
Reader's Guide
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.
Did You Know?
- The MCL35 was the first McLaren car to use a painted matte finish; vinyl wrapping began with the MCL35M in 2021.
- The MCL35 did not set the fastest lap at the 2020 Styrian Grand Prix; that fastest lap was set by Lewis Hamilton.
