Sauber considering Honda and Mercedes power for 2018

Sauber is keeping its options open for 2018 on the power unit front, with both Honda and Mercedes currently under consideration as suppliers.

FIA sporting regulations stipulate that manufacturers have to notify the governing body by May 6 which teams they wish to supply next year, so Sauber's negotiations are likely to ramp up in the coming weeks.

It was reported earlier this week that the Swiss outfit could be viable candidate for Honda power, and even perhaps pick up a baton which McLaren - Honda's works customer - appears all too willing to drop.

Team boss Monisha Kaltenborn has confirmed that preliminary talks have indeed been held with the Japanese manufacturer.

"All I can tell you is yes we have had discussions with them," Kaltenborn told Motorsport.com.

"But we are open on our engine situation. I think we have a couple of options. We know that a call has to be made soon.

"We know that, and of course the sooner you have clarity, the better for development."

Honda planning engine performance upgrade

Mercedes would obviously have Sauber's preference as an engine supplier, but it remains to be seen whether the Hinwill-based outfit could afford the German power unit.

"It's also a possibility," added Kaltenborn.

"Like I said, we have a couple of options, and we are simply not decided."

Sauber could perhaps benefit from the presence in its team of works-supported and Mercedes protégé Pascal Wehrlein, and profit from a partly subsidized deal similar to the one Manor enjoyed last season.

Should McLaren part ways prematurely with Honda (a contractual termination difficult to achieve however) and enter into an agreement with Mercedes for 2018, it remains to be seen if the manufacture could also supply Sauber given the extension of its resources.

Regardless of any future deal, it's unlikely Sauber will extend into next season its current agreement with Ferrari.

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.
