Video: How all the different F1 engines will sound in 2022

Having had to overcome a significant challenge over the winter break due to the changeover to a new 'E10' fuel, the 2022 power units are largely complete as all four engine manufacturers have now fired up their new offerings successfully.

While the engine formula itself remains the same for 2022, F1 introduced a change to running a more sustainable fuel that increases the ethanol content to 10 per cent – a rise from 5.75 per cent.

It has meant a big engineering hurdle for Renault, Honda, Mercedes and Ferrari to overcome, in order to recoup the horsepower loss of moving to a less energy-dense fuel, but all four have fired up their 2022 power units and appear ready for the new season.

The power units will all be homologated on 1 March, as F1 introduces a strict 'engine freeze' on that date that will see all performance-related research and development called to a halt.

Check out all four power units below as they are fired up for the first time!

Mercedes (Mercedes, McLaren, Aston Martin and Williams)
