A month ago, the British luxury carmaker announced it will step up its deal with Red Bull to become title sponsor for 2018.
“Luca Marmorini is helping us on a consultancy basis as we continue to evaluate options for the 2021 power unit,” said Aston Martin in a statement, according to Motorsport.com.
“We have not hired anyone to work full time on this and the power unit remains an area of study for the company, consistent with previous comments and our attendance at the Formula 1 Power Unit Working Group meetings.”
When asked if an engine deal might be the next step, Red Bull boss Christian Horner said: “They can’t do that now, so it would have to be for 2021.”
Aston joined Red Bull as an ‘innovation partner’ ahead of the 2016 F1 season, with the two companies working together to develop the Aston Martin Valkyrie hypercar.
“Our innovation partnership with Aston Martin has been a pioneering project from day one,” said Red Bull team principal Christian Horner.
“Having conceived and created the remarkably successful Aston Martin Valkyrie together in 2016, we extended our relationship this year and are now delighted to further strengthen the partnership and see the team competing as Aston Martin Red Bull Racing in 2018.
“In addition, more than 100 Aston Martin staff will service the new Advanced Performance Centre on our campus here in Milton Keynes and it will allow us to collaborate further with Aston Martin on special, equally innovative, new projects.”
