Charles "Sonny" Ates (born March 28, 1935, Sellersburg, Indiana) is a retired American race car driver.

Ates raced in the USAC Championship Car series in the 1968-1970 seasons, with 15 career starts, including the 1969 Indianapolis 500 (finished 17th). He finished in the top ten 5 times, with his best finish in 5th position in 1968 at Brooklyn.


I believe he held the 1-lap track records at Winchester, Salem, & Dayton at 1 time while driving the #93.
