Frank Luptow

Luptow was inducted in the Michigan Motorsports Hall of Fame in 1988. He was inducted in the National Sprint Car Hall of Fame in 1995.

In 1952, he switched to racing the American Automobile Association (AAA) big cars, champ cars and stock cars. Luptow switched to stock cars at the behest of his wife, who wanted him to quit entirely because of the danger of open-wheel cockpits. He failed to qualify for four champ car events including the 1952 Indianapolis 500. In the stock car, he won twice in August at the Milwaukee Mile and the Terre Haute Action Track. During the September 21, 1952 AAA stock car race at Lakewood Speedway, Luptow's front axle broke causing the car the flip. He was partially ejected out of the car and died shortly afterward of head injuries after the car rolled on top of him. Luptow had previously planned on racing at Terre Haute that day but traveled down to Lakewood as a favor to AAA, who wanted more star power at the Lakewood event.

Luptow started the 1949 season by replacing his Hal engine with an Offenhauser and his car began to be known as the "Black Panther." That season he won 33 of 40 features to take the IMCA national championship. Luptow's most dominating season happened in 1950 as he won 35 of 48 features along with 11 second place finishes. He also competed in a NASCAR Grand National (now Cup Series) stock car race, finishing 18th at the season-opening Daytona Beach Road Course. He started the 1951 season by racing in four NASCAR Grand National races, with finishes of 53rd at Daytona, 5th at Charlotte, 11th at Lakewood Speedway, and 30th at Occoneechee Speedway. In 1951, he won 33 features to win his third straight IMCA championship.

Luptow won 1948 IMCA races at Lebanon, Ohio, Eldon, Iowa, Danville, Illinois, Nashville, Tennessee, Plant Field (Tampa, Florida), Speedway Park (Tampa), and Birmingham, Alabama. He finished third in season points behind Emory Collins and Deb Snyder. After the regular season ended, he kept racing at Tampa-area venues from October to March 1949.

Luptow moved to Detroit, Michigan and won in his first race at Jackson. He raced in several Central States Racing Association (CSRA) races before World War II. During the war, he was a test driver for tanks. After his discharge from the military, he moved back to Detroit and worked for a tank manufacturer. In August 1946, Luptow won his first "big car" (now sprint car) feature at an IMCA event at Davenport Speedway. In 1947, he had 2 Top Ten IMCA finishes at the Iowa State Fairgrounds and finished 20th in season points.

Frank Luptow (born Frank Lueptow) (1914-1952) was an American racing driver. He competed in International Motor Contest Association (IMCA) big cars (now sprint cars) and NASCAR stock cars. He won the 1949, 1950, and 1951 IMCA big car championships.

Luptow was born at Markesan, Wisconsin to Frank and Ida Lueptow in 1914 with Dutch heritage. He later dropped the "E" from his last name.
