Brawn GP may soon sport a Mercedes-Benz three-pointed star after the German automaker commenced discussions to increase its involvement with the championship frontrunners.

Mercedes’ motorsport division handed Brawn a lifeline before the start of the current Formula One campaign, reaching an agreement to supply engines after Honda withdrew from the sport, leaving the outfit without a power plant.

The deal was initially signed on a customer basis, with Mercedes having no visible presence on the British-built Brawn machines.

But the team’s barnstorming success, having won four of the five Grands Prix this year, combined with McLaren’s rapidly falling fortunes, has prompted Mercedes to investigate the possibility of boosting its partnership with Brawn.

Mercedes-Benz motorsport director Norbert Haug says the company doesn’t want to “divert” its focus away from McLaren, but is considering the prospect of forging greater links with Brawn.

“We have possibilities and options and it has been offered to us,” he said, speaking to broadcaster RTL.

Mercedes owns a significant stake in McLaren, but the team’s lack of pace and involvement in the ’steward’s scandal’ earlier in the year cast doubt over the company’s investment. Compounded of course by Daimler’s record losses for the March quarter.

Proving nothing succeeds like success, Brawn’s early season performances now have Stuttgart considering reaching deeper into its pockets.
