"official vehicle of America(tiny little 3 over the last a)"

in 1992, Chevrolet sponsored the America's Cup yacht America³ and so were able to designate the Corvette the "official vehicle of America^{3 "}

So it's a small little thing that might be overlooked when you read the big headline "Official vehicle of America". Nice advertising gimmick.
