Aston Martin Formula 1 team principal Mike Krack believes Fernando Alonso will be a “driving force” in the team’s future prospects when he joins next year.

Alonso signed a multi-year deal with Aston Martin last week to replace retirement-bound Sebastian Vettel after turning down the chance to remain at Alpine.

The two-time world champion has been impressed by the team’s lofty ambitions in a bid to work its way up the grid, with high-profile signings to its expanding technical team and a new factory under construction ready for 2023.

Krack, who assumed his role as team boss at the start of this year, felt Alonso’s arrival was a clear sign of the Silverstone-based outfit’s intent to build itself into a championship-winning team.

“He just has that killer instinct,” Krack said of Alonso. “No matter what, you know that Fernando will always give you everything: always push 100 per cent, always extract the maximum from the car and the team. His racecraft is exceptional – a formidable combination of confidence, instinct and intelligence.

“Signing Fernando is a clear statement of our intent at Aston Martin. We are not on the grid to make up the numbers. We are here to win.

“We are on a journey to the front of the grid and Fernando’s decision to join us on that journey – to have a driver of his calibre believe in the Aston Martin F1 project – is a great compliment to our team and the work we are doing.

“He will demand a lot from us, but that’s to be expected from a multiple world champion. Fernando will be a driving force as we climb together and, like everyone in the team, I cannot wait to work with him.

“The prospect of having Fernando and Lance in the car next year is a hugely exciting one.”

Aston Martin finds itself ninth in the constructors’ standings after the first half of the season, seven points adrift of next-highest team AlphaTauri.

The British manufacturer has struggled to hit the ground running under the 2022 technical regulations, but – while it seeks further improvement – Krack revealed its focus has largely shifted to its 2023 car.

“Although we must continue to improve the performance of the AMR22 and we have a small group of people still working on it, we’ve already turned our attention to the AMR23,” Krack said.

“Our focus has been on AMR23 for a while now because the car needs to perform right out of the box. A new season and new car represent the biggest opportunity to move ahead of our competitors.”
