McLaren, Mercedes: Power Reunion
Last week, F1, the FIA and the championship’s 10 teams opted to delay the introduction of the revolutionary 2021 technical regulations by a year with the 2020 chassis being carried over into next year to save costs in a financially challenging time. McLaren, who currently run Renault power units, had been planning their 2021 design with the architecture of the Mercedes power unit in mind, but they now have to spend resource accommodating it in the 2020 chassis. Despite the challenge, the iconic British team are pushing on with the change. “We will be using the Mercedes engine in 2021 as planned and we will accommodate it in the current base chassis,” said McLaren in a statement. This is far from ideal for McLaren. While the mounting position can be adjusted on the chassis quite easily, the architecture and packaging of every power unit is different. One manufacturer will place its turbo and energy recovery systems in different positions to their rivals. Some have the compressor at the front, others at the back. Equally, the size and shape of those components will be different.
