For his maiden race with Renault last weekend in Austin, Carlos Sainz showed up sporting a fresh clean-cut look but denied the change had anything to do with his new employer.
Scruffy hair, stubble and a backwards-worn cap were often the norm for the Spaniard when he was racing with Toro Rosso.
But as a works Renault driver, the 23-year-old appears to have cleaned up his appearance although he says it has nothing to do with adhering to any sort of corporate standard.
"No, I shave every Thursday," he laughingly said in Mexico .
"I get my hair cut when I get my hair cut, but because I wear a cap, very few people notice.
"The fact is that negotiations about which cap I will wear - Renault or Red Bull - are still going on. So I think when you wear a cap, you can spend less time in front of the mirror?" he added.
Sainz was more interested in talking about his maiden outing with Renault which yielded an impressive P7 finish in Austin and the praise of the team's prestigious special adviser, four-time world champion Alain Prost.
"I know they are happy with the first race so I want to keep this level now," said Sainz.
"Alain Prost is a legend of the sport but also many drivers congratulated me because nobody knows better how hard it is to change teams," he added.
