The struggles of the McLaren team in Formula 1 have been well documented in recent year, but the 2019 season saw them turn the corner with a ‘best of the rest’ fourth place finish in the constructors’ championship, even a podium finish.

With Andreas Seidl settling into his role as team boss, two hungry and talented drivers who genuinely get along well, and a few more sponsors on board for 2020, McLaren may well feature more regularly on podiums with the new MCL35.

Matte paint job aside (which saves a few grams, mind you), the MCL35 does look like it had undergone a strict fitness regime over winter to emerge looking sleeker and fitter, looking quite different from last year’s car which was compromised by a late power unit switch from Honda to Renault.For 2021, McLaren will race with Mercedes power.

McLaren has also published an exhaustive technical specifications for the MCL35 (see below), and it does make for a good read for F1 nerds.
