Jan.31 (GMM) McLaren has played down reports its cars could be powered by engines produced by Craig Pollock's new venture Pure in 2014.
Former BAR founder Pollock is targeting at least two customers for his new turbo V6 engine, and Italy's La Gazzetta dello Sport said there has been contact between Pure and McLaren.
With Mercedes now running its own works team and no longer even a minor McLaren shareholder, the Woking based team faces the prospect of paying for its power beyond this season.
Gazzetta said the change in engine rules would be the ideal time for McLaren to switch.
"Moreover, the contact we did have with Pure, many months ago, was of an entirely informal nature, and was merely a courtesy gesture."
In late November, reports linked McLaren with rumours Honda is looking to return to F1 in 2014 as an engine supplier.
"We are very happy with and enjoying our partnership with Mercedes-Benz," team managing director Jonathan Neale insisted at the time.
