Following another successful outing on the WTA Tour in 2025, Coco Gauff is now making waves off the court in the off-season. She became the global brand ambassador for the luxury automobile giant Mercedes-Benz, and her family couldn't contain their joy about the same.The Mercedes-Benz group needs no introduction. Founded in Germany in 1886, it has been one of the go-to cars for die-hard motorheads. Despite being in business for over a century, the demand for their finely-crafted machines hasn't dented in the slightest. It's not surprising to note that the company posted $11 billion in profit this year (as per Forbes). They took to social media to break the news of Gauff repping their brand henceforth."Power. Precision. Play without limits. We’re proud to welcome world-class tennis player @cocogauff to the Mercedes-Benz family as a new global brand ambassador," Mercedes-Benz's official account on Instagram.
