McLaren will switch to Mercedes engines as planned in 2021

McLaren will have to redesign the 2020 car to fit a Mercedes Power Unit instead of the Renault

McLaren says its switch from Renault to Mercedes engines will go ahead as planned next year despite McLaren designing a new car for 2021 to fit the Mercedes power unit and then being told Formula 1 teams are required to run the same cars for two years.

F1 has agreed to delay the 2021 technical regulation overhaul by a year until 2022, meaning that teams will carry over the chassis they run this year into next season, as discussed during a conference call involving all teams on Thursday.

A McLaren spokesperson told Crash.net: "We will be using the Mercedes engine in 2021 as planned and we will accommodate it in the current base chassis."
