Honda  will be supplying a second customer from 2018, and given the power unit contracts of its rivals currently, the logical customer of choice is Sauber.

Indeed the Swiss outfit has not renewed its engine contract with Ferrari,according to German publication Auto, Motor und Sport, which makes the Hinwill-based outfit the most probable recipient of Honda's power.

The Japanese manufacturer has endured trying times since it returned to Grand Prix racing with McLaren in 2015, but an all-new engine design for 2017 has rekindled the partnerships ambitions.

In December, Honda Racing boss Yusuke Hasegawa confirmed that the company was ramping up its efforts to supply a second team in 2018, extending its real estate accordingly at its Milton Keynes factory.

But Hasegawa also said that any subsequent deal would have to be signed and sealed by this year's Monaco Grand Prix at the latest.

Sources indicate that talks are now well underway between Honda and Sauber. Should they for any reason fall apart, Sauber would rely on the FIA to compel a manufacturer to supply any team without an engine contract.

It's uncertain whether the presence at Sauber of Pascal Wehrlein, a Mercedes protégé, would have any bearing on the team's choice of power.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
