Corvette C1 (1953–1962)









CORVETTE C1 - The first generation Corvette was introduced late in the 1953 model year. Originally designed as a show car for the 1953 Motorama display at the New York Auto Show, it generated enough interest to induce GM to make a production version to sell to the public. To keep costs down, GM executive Robert F. McLean mandated off-the-shelf mechanical components, and used the chassis and suspension from the 1952 Chevy sedan. The drivetrain and passenger compartment were moved rearward to achieve a 53/47 front-to-rear weight distribution. It had a 102-inch wheelbase. The engine was the same inline six that powered all other Chevrolet models, but with a higher-compression ratio, three Carter side-draft carburetors, and a more aggressive cam. Output was 150 horsepower. Because there was currently no manual transmission available to Chevrolet rated to handle 150 HP, a two-speed Powerglide automatic was used. 0-60 mph time was 11.5 seconds. To keep tooling costs in line, the body was made out of fiberglass instead of steel. First production was on June 30, 1953.

This generation was often referred to as the "solid-axle" models (the independent rear suspension was not introduced until the second generation). 300 hand-built polo white Corvette convertibles were produced for the 1953 model year.

The 1954 model year arrived quickly. It could now be ordered in Pennant Blue, Sportsman Red and Black, or Polo White. 3,640 were built, and sold slowly.

The 1955 model offered a 265 cu in (4.34 L) V8 engine as an option. With a large inventory of unsold 1954 models, GM limited production to 700 for 1955. With the V8, 0-60 mph time improved to 8.5 seconds.

A new body was introduced for the 1956 model featuring a new "face" and side coves; the taillamp fins were also gone. An optional fuel injection system was made available in the middle of the 1957 model year. It was one of the first mass-produced engines in history to reach 1 bhp (0.75 kW) per cubic inch (16.4 cubic cm) and Chevrolet's advertising agency used a "one hp per cubic inch" slogan for advertising the 283 bhp (211 kW) 283 cu in (4.64 L) Small-Block engine. Other options included power windows (1956), hydraulically operated power convertible top (1956), heavy duty brakes and suspension (1957), and four speed manual transmission (late 1957).

The 1958 Corvette received a body and interior freshening which included a longer front end with quad headlamps, bumper exiting exhaust tips, a new steering wheel, and a dashboard with all gauges mounted directly in front of the driver. Exclusive to the 1958 model were hood louvers and twin trunk spears. The 1959–60 model years had few changes except a decreased amount of body chrome and more powerful engine offerings.

In 1961, the rear of the car was completely redesigned with the addition of a "duck tail" with four round lights. The light treatment would continue for all following model year Corvettes.

In 1962, the Chevrolet 283 cu in (4.64 L) Small-Block was enlarged to 327 cu in (5.36 L). In standard form it produced 250 bhp (190 kW). For an extra 12% over list price, the fuel-injected version produced 360 bhp (270 kW) , making it the fastest of the C1 generation. 1962 was also the last year for the wrap around windshield, solid rear axle, and convertible-only body style. The trunk lid and exposed headlamps did not reappear for many decades
