F1 teams are knocking on Aston Martin's door!

Aston Martin's potential involvement in F1 as an engine supplier from 2021 has drawn the interest of several teams.

The iconic luxury car manufacturer has upped its investment in the sport and will become Red Bull Racing's title sponsor this year.

But Aston Martin is also pondering the idea of becoming an independent engine supplier from 2021, when Formula 1's new engine rules will be introduced.

Aston Martin CEO Andy Palmer believes the draft proposal tabled two months ago by Ross Brawn goes in the right direction as it favors a less sophisticated and cheaper future power unit for F1.

Red Bull and Toro Rosso appear as likely candidates for a batch of Aston Martin engines, but Palmer has revealed that several other teams on the current grid have declared themselves interested in an eventual supply.

Aston's plans are in their early stages however, with a huge amount of feasibility work still remaining.

"I have some rough math in terms of what cost and what price," Palmer told Motorsport.com.

"With all of this stuff in F1, you have to factor in intangibles because you’re talking about a marketing return, not necessarily a physical return.

"Marketing return hopefully turns into sold cars, which is why we’re doing this.

"This is to seed the soil for when we bring a mid-engined car to compete with the Ferrari 488, which is what the Valkyrie [hypercar] was about.

"It’s about creating credibility ready for when we go mainstream face-to-face with Ferrari, Lamborghini and McLaren on the road.

"The timing of the 2021 regulations work really well, because it is about the time we’ll be bringing that car out."
