Chevrolet Corvette - Dale Duncan - 12 Hours of Sebring race 1957

Description: A superb and rare phototive, of the nr. 5 Chevrolet Corvette , photographed during the 1957 edition of the 12 Hours of Sebring endurance race.The number 5 Chevrolet Corvette was entered by Raceway Enterprises in the Sports 5000 class; and driven by Dale Duncan. Unfortunately he was forced to retire due to driveshaft problems. The Chevrolet Corvette is a sports car that has been manufactured by Chevrolet since 1953. While the style of a car may be just as important to some as to how well the car runs, it was not until 1927, when General Motors hired designer Harley Earl, that automotive styling and design became important to American automobile manufacturers. What Henry Ford did for automobile manufacturing principles, Harley Earl did for car design. Taking its name from the corvette, a small, maneuverable fighting frigate (the credit for the naming goes to Myron Scott), the first Corvettes were virtually handbuilt in Flint, Michigan in Chevrolet's Customer Delivery Center, now an academic building at Kettering University. The outer body was made out of then-revolutionary fiberglass, selected in part because of steel quotas left over from the war. Underneath the new body material were standard Chevrolet components, including the "Blue Flame" inline six-cylinder truck engine, two-speed Powerglide automatic transmission, and drum brakes from Chevrolet's regular car line. Though the engine's output was increased somewhat, thanks to a triple-carburetor intake exclusive to the Corvette, performance of the car was decidedly lackluster. Compared to the British and Italian sports cars of the day, the Corvette was underpowered, required a great deal of effort as well as clear roadway to bring to a stop, and even lacked a "proper" manual transmission. Up until that time, the Chevrolet division was GM's entry-level marque, known for excellent but no-nonsense cars[citation needed]. Nowhere was that more evident than in the Corvette[citation needed]. A Paxton supercharger became available in 1954 as a dealer-installed option, greatly improving the Corvette's straight-line performance, but sales continued to decline. GM was seriously considering shelving the project, leaving the Corvette to be little more than a footnote in automotive history, and would have done so if not for two important events. The first was the introduction in 1955 of Chevrolet's first V8 engine (a 265 in³ {4.3 L}) since 1919, and the second was the influence of a Soviet émigré in GM's engineering department, Zora Arkus-Duntov. Arkus-Duntov simply took the new V8 and backed it with a three-speed manual transmission. That modification, probably the single most important in the car's history[citation needed], helped turn the Corvette from a two-seat curiosity into a genuine performer. It also earned Arkus-Duntov the rather inaccurate nickname "Father of the Corvette." Another key factor in the Corvette's survival was Ford's introduction, in 1955, of the two-seat Thunderbird, which was billed as a "personal luxury car", not a sports car. Even so, the Ford-Chevrolet rivalry in those days demanded that GM not appear to back down from the challenge. The "T-Bird" was changed to a four-seater in 1958. There have been six generations of the Corvette so far, sometimes referred to as C1 through C6. Sebring started life as a United States Army Air Forces training base. From 1941 to 1946, pilots learned to fly the B-17 Flying Fortress. After World War II, aeronautical engineer Alec Ullman, seeking sites to restore military aircraft for civilian use, saw potential in Hendricks' runways to stage a sports car endurance race, similar to the 24 Hours of Le Mans. Sebring's first race was held on New Year's Eve of 1950. The Sam Collier 6 Hour Memorial race was won by Frits Koster and Ralph Deshon in a Crosley Hot Shot. This first race attracted thirty racecars from across North America. The first 12 Hours of Sebring was held on March 15th, 1952, and would grow to be a major international race. In 1959, the racetrack hosted the first Formula One United States Grand Prix. Due to the poor attendance and high costs, the next United States Grand Prix was held at Riverside. For much of Sebring's history, the track followed a 5.38 mile (8.66 km) layout, these days the course of the track is 3.7 miles (5.95 km) long. It is a seventeen-turn road course with long straights, several high-speed corners, and very technical slower corners. Many of the turns and points along the track are named for the early teams and drivers. There is very little elevation change around the track and little camber on the surface, providing a challenging track for drivers, especially when it rains. Sebring is renowned for its rough surface. The course still runs on old sections of World War II-era landing fields that were constructed of concrete sections with large seams. The transitions between sections are quite rough and often, sparks fly from the undercarriages of the cars as they traverse them. Much of the track has intentionally been left with its original concrete runway surface. The track surface has 2.4 miles of asphalt and 1.2 miles of concrete. The 12 Hours of Sebring race has a rich history, as legendary drivers such as Mario Andretti, Briggs Cunningham, Juan Manuel Fangio, A.J. Foyt, Jacky Ickx, Stirling Moss and Lake Underwood, and manufacturers such as Ferrari, Porsche, BMW, Jaguar, Cunningham, Audi and Ford have all been victorious. It is known as an excellent preparation for the famous 24 Hours of Le Mans.
