Charles G. Ewing, 62, the automotive editor of The Washington Star until the newspaper closed last August and a retired lieutenant colonel in Army intelligence, died at Fairfax Hospital Monday after a heart attack.

Mr. Ewing joined the Star in 1969 and was named automotive editor in 1971. He was best-known for two features, "From Washington," which he wrote under his own name, and "Car Questions," which he wrote under the name "Kent Goforth." At one time, his columns were syndicated in more than 100 newsapers around the country.

Apart from The Star, the Journal Newspapers in the Washington suburbs also carried Mr. Ewing's work.

Mr. Ewing's other publications included a pictorial history called "Yesterday's Washington," which is part of a series about urban areas in the United States, and contributions to various magazines and yearbooks.

A native of Powell Station, Tenn., Mr. Ewing was a graduate of the University of Tennessee. He began his career in journalism with radio stations in Knoxville, Tenn., and Columbus, Ga.

During World War II, he went into the Army and served as a counterintelligence officer in France and Germany. From 1946 to 1951, he was the city editor of The Columbus (Ga.) Ledger-Enquirer. He was recalled to active duty in 1951 during the Korean conflict and thereafter made the Army his career.

He served in Korea during the war there and later in Japan and West Berlin as well as at various posts in this country. He was stationed in Washington when he retired in 1966 with the rank of lieutenant colonel.

Before joining The Star, he was an associate editor of The Journal of Homebuilding and a copy editor at The Washington Post and the Atlanta (Ga.) Constitution.

Mr. Ewing, who lived in Fairfax, is survived by his wife, Helen B., of Fairfax; a daughter, Margaret Mary Ewing of Fairfax; four sons, Lee, of Laurel, Gerald H., of Silver Spring, and Charles G. and David, both of Fairfax; a sister, Dora B. Ewing of Atlanta, and four grandchildren.
