Race engineers are among the most familiar voices in Formula 1, but not much is known about most of them apart from a few key names.
Lewis Hamilton's engineer 'Bono' is a household name for F1 fans - or at least his nickname is.
During a race, the job of the race engineer is to relay messages between the driver and the engineering team to help improve performance, provide solutions and offer advice.
It is a high-pressure job which requires excellent communication skills as well as a complete understanding of both the driver and the car.
As a result, many drivers will retain the same race engineer for multiple seasons as two-way trust is important for ensuring maximum performance when on the track.
F1 race engineers in 2023
With many drivers changing teams in 2023 and some rookie drivers on the grid, numerous race engineer pairings have changed for this season.
Many of the veteran drivers have retained their long-term engineer for 2023, but some, like Fernando Alonso who switched team to Aston Martin has a new voice on his radio.
Lewis Hamilton - Peter Bonnington
Peter Bonnington is better known by his nickname 'Bono' and has been Lewis Hamilton's engineer for the past 11 seasons.
Bonnington started out as a data engineer for Jordan before a stint at Honda working with Jenson Button.
At Mercedes, he worked with Michael Schumacher and then became Hamilton's race engineer, being responsible for the famous 'Hammertime' radio calls.
Hamilton revealed that Bono is one of few people who can 'truly stand him' stating: “We’ve had an amazing journey together, we’ve supported each other on and off-track, through good and bad times, and I love working with Bono; he’s like a brother to me, a brother from another mother.
Bonnington's number two was promoted to George Russell's engineer for the 2023 season.
Russell had worked with Riccardo Musconi last season, but had a vacant spot this year after Musconi was promoted to performance engineer at Mercedes.
Dudley had previously stepped in to fill Bono's shoes at the 2022 Australian Grand Prix, where he was heard over the radio talking to Hamilton.
Dudley has previously worked with Honda, Arden International and Marussia.
Chelsea-supporter Gianpiero Lambiase was born in London and is affectionately called 'GP' by Max Verstappen.

He later worked with Paul di Resta and Sergio Perez, before moving to Red Bull in 2014.
His stint as Daniil Kyvat's race engineer didn't last too long as the young driver was replaced by Max Verstappen, and since then 'GP' has been the Dutchman's partner on the radio.
Verstappen was disappointed to see Lambiase's low rating in F1 Manager 2022, telling Motorsport NL "The evaluation of Gianpiero Lambiase is insanely low. Probably someone was drunk when he decided on his rating. I’ll talk to whoever is responsible."

Oscar Piastri - Tom Stallard
Tom Stallard is an Olympic medalist and a race engineer. He won a silver medal at the 2008 Olympics in Beijing for rowing, but hung up his oars straight after the summer games to move to McLaren.
“I was leaving the country with the GB rowing team for our pre-2008 Olympics altitude training camp in Silvretta, Austria when I had a phone call asking me when I could start at McLaren," he told World Rowing.

As a race engineer, Jego feels he has to conduct the full orchestra on race day: “Being an engineer is a bit like becoming a conductor. A Formula 1 car is quite complicated to drive. We have to manage the tyres, the petrol or the weather. The driver is obviously our priority."
How much does an F1 race engineer earn?
Graduate engineers can earn between £25,000 and £30,000 a year working in F1, but by the time they get to the level of a senior engineer or chief engineer, this figure is greatly increased.
Senior engineer salaries are around £70,000 to £115,000 a year, and a chief engineer may earn upwards of £175,000.
Race engineers are among the most important members of F1 teams, so their salaries will reflect this, especially at the larger teams who are competing for the Constructors' Championship.
