Driving a reconfigured Indy car at the newly opened Daytona International Speedway, Teague died while attempting to break the closed course speed record, which had been established by Tony Bettenhausen in qualifying for the 1957 Race of Two Worlds at about 177 mph. Teague was conducting test sessions in preparation for the April start of the 1959 USAC Championship Car season, piloting a "Sumar Special" streamliner, a Kurtis Kraft chassis with a 270 c.i. Meyer-Drake Offenhauser engine, streamlined fenders, and a canopy enclosing the driver, thus being classified as Formula Libre.
