"If we do an engine, we won't do it by ourselves. We'll start now to look for partners.

"We are starting that study now in parallel to the machination of the regulations."

Aston staff recruits with F1 'brainpower' include Ferrari personnel
Aston Martin has recruited staff with Formula 1 experience, including personnel from Ferrari, as it continues to evaluating entering the championship as an engine supplier.

The British manufacturer will become Red Bull Racing's title sponsor in 2018 as part of an enhanced relationship that has already yielded the Valkyrie hypercar.

Aston is taking a close interest in F1's 2021 engine rules but president and CEO Andy Palmer has said costs need to be kept under control for the project to be viable.

Red Bull boss Christian Horner has said his team is "absolutely open" to running an Aston Martin engine if it decides to pursue the project.
