Chevrolet Corvette (C1) 1956
Hackberry is an unincorporated community in Mohave County, Arizona, United States. Hackberry is located on Arizona State Route 66 (former U.S. Route 66) 23 miles (37 km) northeast of Kingman. Hackberry has a post office which serves 68 residential mailboxes with ZIP code 86411.
A former mining town, Hackberry takes its name from the Hackberry Mine which was named for a hackberry tree in a nearby spring.
Prospector Jim Music helped develop the Hackberry Silver Mine in 1875. Mining of various metals developed the town, sending it from boom to bust based on fluctuating commodity prices.
The Indianapolis Monroes Iron Clad Age of June 12, 1886 includes a brief article titled "They Changed the Minds of Several" referring to an educated miner from the area.
J.J. Watts writes from Hackberry, Arizona: "The books you sent me last year have changed the minds of several to whom I loaned them. It is a pity that liberal books and papers cannot be more generally circulated and read. If they could be we should soon have more outspoken, honest men that would dare to speak their true sentiments."
Based on an article taken from the July 24, 1909 edition of the Mohave County Miner out of Kingman, Arizona, JJ Watts was an old prospector. Here is that article.
"Some time ago the report was current in Kingman that Indians had killed an old prospector, in the Wallapai mountains, first burying the body and later burning up everything of an incriminating nature. The man was supposed to be J. J. Watts, who mined and prospected in the Music mountain range many years. William Grant, the Hackberry merchant, this week received a letter from B.F. Watts, of Marshall, Oklahoma, conveying the information that J.J. Watts died at Lander, Wyoming, last winter. The man who was killed by the Indians is believed to be a stranger that came to Kingman and was lured to the mountains by the Indians by a story of a lost mine that they had found in that section. The man was killed by Willietopsy and his sons, so it is reported by the other Indians.
By 1919, infighting between the mine's owners had become litigation and the ore was beginning to be depleted. The mine closed; Hackberry briefly almost became a ghost town.
Various service stations in town served U.S. Route 66 travellers after the highway came to town in 1926; all were shut down after Interstate 40 in Arizona bypassed the town. Interstate 40's 69-mile path between Kingman and Seligman diverges widely from the old 82-mile Highway 66 segment between these points, leaving Hackberry stranded sixteen miles from the new highway. Hackberry Road would not even be given an off-ramp. John Grigg operated a Union 76 service station on Route 66 in Hackberry from the 1920s until his death in 1967. The Northside Grocery (established 1934) and its Conoco station were among the last to close, in 1978.
Hackberry almost became a ghost town again, but members of the Grigg family have lived there since the 1890s and continue to live there. Six generations of the Grigg family are buried in the Hackberry cemetery.
In 1992, itinerant artist Bob Waldmire re-opened the Hackberry General Store as a Route 66 tourism information post and souvenir shop on the former Northside Grocery site.
Waldmire sold the store to John and Kerry Pritchard in 1998 due to local disputes regarding the environmental and aesthetic impact of quarries, which by that time were establishing themselves in the area to remove local stone for use in landscaping.
The store remains in operation with a collection of vintage cars from the heyday of U.S. Route 66 in Arizona; in 2008, its owners donated land for a new fire hall to be built for the community.

The Chevrolet Corvette (C1) is the first generation of the Corvette sports car produced by Chevrolet. It was introduced late in the 1953 model year and produced through 1962. This generation is commonly referred to as the "solid-axle" generation, as the independent rear suspension did not appear until the 1963 Sting Ray.
The Corvette was rushed into production for its debut model year to capitalize on the enthusiastic public reaction to the concept vehicle, but expectations for the new model were largely unfulfilled. Reviews were mixed and sales fell far short of expectations through the car's early years. The program was nearly canceled, but Chevrolet decided to make necessary improvements.
The most expensive Corvette (C1) to sell in history was sold by Barrett-Jackson in the United States in March 2021 for $825,000 (~$915,195 in 2023) (£591,470).
History
Origins
Harley Earl, as head of GM's Styling Section, was an avid fan of sports cars. He recognized that GIs returning after serving overseas in the years following World War II were bringing home MGs, Jaguars, and Alfa Romeos. In 1951, Nash Motors began selling an expensive two-seat sports car, the Nash-Healey, that was made in partnership with the Italian designer Pininfarina and British auto engineer Donald Healey, but there were few moderate-priced models. Earl convinced GM that they needed to build an all-American two-seat sports car, and with his Special Projects crew began working on the new car in late 1951. The last time Chevrolet offered a 2-door, 2-passenger convertible/roadster body style was in 1938 with the Chevrolet Master.
Prototype EX-122
The secretive effort was code-named "Project Opel" (after GM's German division Opel). The result was the hand-built, EX-122 pre-production Corvette prototype, which was first shown to the public at the 1953 General Motors Motorama at the Waldorf-Astoria in New York City on January 17, 1953. When production began six months later, at an MSRP of US$3,513 ($40,006 in 2023 dollars ), it had evolved into a considerably costlier car than the basic $2,000 roadster Harley Earl originally had in mind. The EX-122 car is now located at the Kerbeck Corvette museum in Atlantic City and is believed to be the oldest Corvette in existence.
Design and engineering
To keep costs down, GM executive Robert F. McLean mandated off-the-shelf mechanical components. The new car used the chassis and suspension design from the 1949 through 1954 Chevrolet passenger vehicles. The drivetrain and passenger compartment were moved rearward to achieve a 53/47 front-to-rear weight distribution. It had a 102 in (2,591 mm) wheelbase. The engine was a 235 cu in (3.85 L) inline six engine that was similar to the 235 engine that powered all other Chevrolet car models, but with a higher-compression ratio, three Carter side-draft carburetors, mechanical lifters, and a higher-lift camshaft. Output was 150 hp (112 kW). Because there was currently no manual transmission available to Chevrolet rated to handle 150 HP, a two-speed Powerglide automatic was used. The 0–60 mph (0–97 km/h) time was 11.5 seconds.
Three body variants were created. The roadster was built as the Corvette, the Corvair fastback variant never went into production, and the two-door Nomad station wagon was eventually built as the Chevrolet Nomad.
During the last half of 1953, 300 Corvettes were to a large degree hand-built on a makeshift assembly line that was installed in an old truck plant in Flint, Michigan, while a factory was being prepped for a full-scale 1954 production run. The outer body was made of then-revolutionary glass fiber reinforced plastic material. Although steel shortages or quotas are sometimes mentioned as a factor in the decision to use fiberglass, no evidence exists to support this. In calendar years 1952 and 1953, Chevrolet produced nearly 2 million steel-bodied full-size passenger cars, and the intended production volume of 10,000 Corvettes for 1954 was only a small fraction of that.
The body engineer for the Corvette was Ellis James Premo. He presented a paper to the Society of Automotive Engineers in 1954 regarding the development of the body.
Several excerpts highlight some of the key points in the body material choice:
The body on the show model was made of reinforced plastic purely as an expedient to get the job done quickly.
Although we were going ahead with the building of an experimental plastic body in order to get a car rolling for chassis development work – at the time of the Waldorf Show, we were actually concentrating body-design-wise on a steel body utilizing Kirksite tooling for the projected production of 10,000 units during the 1954 model year. It was some time later that we decided to produce this quantity in reinforced plastic.
About this time, some doubt was expressed that we should build the 1954 model of steel. People seemed to be captivated by the idea of the fiberglass plastic body. Furthermore, information being given to us by the reinforced plastic industry seemed to indicate the practicality of fabricating plastic body parts for automobiles on a large scale.
A 55-degree raked windshield was made of safety glass, while the license plate holder was set back in the trunk, covered with a plastic window. Underneath the new body material were standard components from Chevrolet's regular car line, including the "Blue Flame" inline six-cylinder engine, two-speed Powerglide automatic transmission, and drum brakes. The engine's output was increased to 150 hp (112 kW) via a Carter triple-carburetor system exclusive to the Corvette, but performance of the car was decidedly "lackluster". Compared to the British and Italian sports cars of the day, the Corvette lacked a manual transmission and required more effort to bring to a stop, but like their British competition, such as Morgan, was not fitted with roll-up windows;[19] this would have to wait until some time in the 1956 model year. A Paxton centrifugal supercharger became available in 1954 as a dealer-installed option, greatly improving the Corvette's straight-line performance, but sales continued to decline.
The Chevrolet division was GM's entry-level marque. Managers at GM were 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 three important events. The first was the 1955 introduction of Chevrolet's first V8 engine since 1919. Late in the model year, the new 195 hp (145 kW) 265 small-block became available with a Powerglide automatic transmission, until the middle of the production year when a manual 3-speed became available, coupled to a 3.55:1 axle ratio, the only one offered. The engine was fitted with a single 2218S or 2351S WCFB four-barrel (four-choke) Carter carburetor. The combination turned the "rather anemic Corvette into a credible if not outstanding performer". The second was the influence of a Russian émigré in GM's engineering department, Zora Arkus-Duntov. The third factor in the Corvette's survival was Ford's introduction of the 1955 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 GM not appear to back down from the challenge. The original concept for the Corvette emblem incorporated an American flag into the design, but was changed well before production, since associating the flag with a product was frowned upon.
1953–1955
1953
The 1953 model year was not only the Corvette's first production year, but at 300 produced it was also the lowest-volume Corvette. The cars were essentially hand-built and techniques evolved during the production cycle so that each 1953 Corvette is slightly different. All 1953 models had red interiors, Polo white exteriors, and painted blue engines (a reference to the three colors represented on the Flag of the United States, where the Corvette was assembled) as well as black canvas soft tops. Order guides showed heaters and AM radios as optional, but all 1953 models were equipped with both. Over two hundred 1953 Corvettes are known to exist today. They had independent front suspension, but featured a rigid axle supported by longitudinal leaf springs at the rear. The cost of the first production model Corvettes in 1953 was US$3,490 ($38,795 in 2023 dollars).
The quality of the fiberglass body as well as its fit and finish were lacking. Other problems, such as water leaks and doors that could open while the car was driven, were reported with the most severe errors corrected in subsequent units produced, but some shortcomings continued beyond the Corvette's inaugural year. By December 1953, Chevrolet had a newly equipped factory in St. Louis ready to build 10,000 Corvettes annually. However, negative customer reactions to 1953 and early 1954 models caused sales to fall short of expectations.
1954
In 1954, a total of 3,640 of this model were built and nearly a third were unsold at year's end. New colors were available, but the six-cylinder engine and Powerglide automatic, the only engine and transmission available, were not what sports car enthusiasts expected. It is known that 1954 models were painted Pennant Blue, Sportsman Red, and Black, in addition to Polo White. All had red interiors, except for those finished in Pennant Blue which had a beige interior and beige canvas soft top. Order guides listed several options, but all options were "mandatory" and all 1954 Corvettes were equipped the same.
In the October 1954 issue of Popular Mechanics, there was an extensive survey of Corvette owners in America. The surprising finding was their opinions in comparison to foreign sports cars. It was found that 36% of those taking the survey had owned a foreign sports car, and of that, half of them rated the Corvette as better than their previous foreign sports car. Nineteen percent rated the Corvette as equal to their foreign sports car and 22% rated the Corvette as inferior. While many were well pleased with the Corvette, they did not consider it a true sports car. The principal complaint of the surveyed owners was the tendency of the body to leak extensively during rainstorms.
1955
Chevrolet debuted its 265 cu in (4.3 L) small-block, 195 hp (145 kW) V8 in 1955 and the engine was available for the Corvette. Early production 1955 V8 Corvettes continued with the mandatory-option Powerglide automatic transmission (as did the few 6-cylinder models built). A new three-speed manual transmission became available later in the year for V8 models, but was not popular with about 75 equipped with it. Exterior color choices were expanded to at least five, combined with at least four interior colors. Soft-tops came in white, dark green, or beige and different materials. A total of 700 1955 Corvettes were built, making it second only to 1953 in scarcity. The "V" in the Corvette emblem was enlarged and gold colored, signifying the V8 engine and 12-volt electrical systems, while 6-cylinder models retained the 6-volt systems used in 1953–54.
Although not a part of the original Corvette project, Zora Arkus-Duntov was responsible for the addition of the V8 engine and three-speed manual transmission. Duntov improved the car's marketing and image and helped the car compete with the new V8—engined Ford Thunderbird, Studebaker Speedster and the larger Chrysler C-300, and turned the Corvette from its lackluster performance into a credible performer. In 1956 he became the director of high-performance vehicle design and development for Chevrolet helping him earn the nickname "Father of the Corvette."
Although the C1 Corvette chassis and suspension design were derived from Chevrolet's full-size cars, the same basic design was continued through the 1962 model even after the full-size cars were completely redesigned for the 1955 model year. This was due to the combined factors of the relatively high reengineering and retooling costs for this low-volume production vehicle, the continued potential for cancellation of the car, and the increased size and weight of the all-new suspension design for the full-size cars, which made it unsuitable for use in the lighter weight Corvette.
1956–1957
1956
The 1956 Corvette featured a new body, with real glass roll-up windows and a more substantial convertible top. The straight-6 engine was discontinued, leaving only the 265 cu in (4.3 L) V8. Power ranged from 210 to 240 hp (157 to 179 kW). The standard transmission remained the 3-speed manual with an optional 2-speed Powerglide automatic. Other options included power assisted convertible top, a removable hardtop, power windows, and a "then-leading edge" signal-seeking partially transistorized Delco car radio. A high-performance camshaft was also available (as RPO 449) with the 240 hp (179 kW) engine. Sales volume was 3,467, a low number by any contemporary standard and less than 1954's 3,640, making it the third lowest in Corvette history.
1957
Visually the 1957 model was unchanged. The V8 was increased to 283 cu in (4.6 L), fuel-injection became a very expensive option, and a 4-speed manual transmission became available after April 9, 1957. GM's Rochester subsidiary used a constant flow system, producing a listed 290 hp (216 kW) at 6200 rpm and 290 lb⋅ft (393 N⋅m) of torque at 4400 rpm. Debate continues to swirl whether this was underrated by Chevrolet (to allow for lower insurance premiums, or give the car an advantage in certain forms of racing) rather than overrated, as was common practice at the time (to juice sales). Either way, it was advertised as producing "One HP per cubic inch", allowing it to claim it was one of the first mass-produced engines to do so.
Pushed toward high-performance and racing, principally by its designer, Zora Arkus-Duntov, who had raced in Europe, 1957 Corvettes could be ordered ready-to-race with special performance options, such as an engine fresh air/tach package, heavy-duty racing suspension, and 15 by 5.5 in (380 by 140 mm) wheels.
Also in 1957, Chevrolet developed a new racing variation of the Corvette with the aim to compete in the 24 Hours of Le Mans race. Originally known as Project XP-64, it would eventually become known as the Corvette SS. It featured a tuned version of the new 283 CID V8 and a specialized tubular space frame chassis. However, after a rear bushing failure retired the car during a 1957 Sebring race, the AMA announced a ban on motor racing in April 1957 for member companies like GM, leading to the cancellation of further developments of the Corvette SS platform.
Sales volume was 6,339, a jump of almost 83%. Fuel-injected models were in short supply and 1,040 were sold.
1958–1960
1958
In an era of chrome and four headlamps, the Corvette adapted to the look of the day. The 1958 model year and the four that followed all had the exposed four-headlamp treatment and prominent grilles, but a faux-louvered hood and chrome trunk spears were unique to this model year. The interior and instruments were updated, including placing a tachometer directly in front of the driver. For the 1958 model, an 8000 rpm tachometer was used with the 240 and 290 hp (179 and 216 kW) engines, rather than the 6000 rpm units used in the lower horsepower engines. Optional engine choices included two with twin carburetors (including a 270 hp (201 kW) version with Carter 2613S and 2614S WCFB four-barrels) and two with fuel injection. The power output for the highest-rated fuel-injected engine was 290 hp (216 kW). Displacement remained 283 cu in (4.6 L). For the first time, seat belts were factory-installed rather than dealer-installed as on previous models. Options that were not popular included RPO 684 heavy-duty brakes and suspension (144), RPO 579 250 hp (186 kW) engine (554), and RPO 276 15×5.5-inch steel road wheels (404).
1959
For the 1959 model, engines and horsepower ratings did not change. The interiors were revised slightly with different instrument graphics and the addition of a storage bin to the passenger side. A positive reverse lockout shifter with "T" handle was standard with 4-speed manual transmission. This was the only year a turquoise convertible top color could be ordered, and all 24-gallon fuel tank models through 1962 could not be ordered with convertible tops due to inadequate space for the folding top mechanism.[26] Rare options: RPO 684 heavy-duty brakes and suspension (142), RPO 686 metallic brakes (333), RPO 276 15"×5.5" wheels (214), RPO 426 power windows (547), RPO 473 power convertible top (661).
1960
The last features to appear in 1960 models included taillamps molded into the rear fenders and heavy grill teeth. New features include aluminum radiators, but only with 270 and 290 hp (201 and 216 kW) engines. Also for the first time, all fuel-injection engines required manual transmissions. The 1960s Cascade Green was metallic, unique to the year, and the most infrequent color at 140 made. Options that were not often ordered included RPO 579 250 hp (186 kW) engine (100), RPO 687 heavy-duty brakes and suspension (119), RPO 276 15×5.5-inch steel road wheels (246), RPO 473 power convertible top (512), and RPO 426 power windows (544).
1961–1962
1961
Twin taillights appeared on the 1961, a treatment that continues to this day. Engine displacement remained at 283 cubic inches, but power output increased for the two fuel-injected engines to 275 and 315 hp (205 and 235 kW). Output ratings for the dual-four barrel engines did not change (245 and 270 hp (183 and 201 kW)), but this was the last year of their availability. This was the last year for contrasting paint colors in cove areas, and the last two-tone Corvette of any type until 1978. Also debuting in 1961 was a new boat-tail that was carried through to the C2. Infrequently ordered options included RPO 353 275 hp (205 kW) engine (118), RPO 687 heavy-duty brakes and steering (233), RPO 276 15×5.5-inch steel road wheels (357), and RPO 473 power convertible top (442).
1962
With a new larger engine the 1962 model year Corvette was the quickest to date. Displacement of the small-block V8 increased from 283 cu in (4.6 L) to 327 cu in (5,360 cc), which was rated at 250 hp (186 kW) in its base single 4-barrel carburetor version. Hydraulic valve lifters were used in the standard and optional 300 hp (224 kW) engines, solid lifters in the optional carbureted 340 hp (254 kW) and fuel-injected 360 hp (268 kW) versions. Dual 4-barrel carburetor engines were no longer available.
1962 saw the last solid-rear-axle suspension, that had been used from the beginning. Rocker panel trim was seen for the first time, and exposed headlights for the last, until 2005. This was the last Corvette model to offer an optional power convertible top mechanism. Rare options: RPO 488 24-gallon fuel tank (65), RPO 687 heavy-duty brakes and steering (246), RPO 473 power convertible top (350), RPO 276 15"×5.5" wheels (561).
Scaglietti Corvette
In 1959, a Texan oil well drilling contractor named Gary Laughlin wondered if it would be possible to create a vehicle with Italian design characteristics using the chassis and engine components from an American car like the Corvette. To oversee this creation, he enlisted the help of car constructer Jim Hall and race car driver Carroll Shelby, whom he was good friends with, to assist with the engineering of the project and, after their efforts, each man was to receive their own Corvette custom made to their liking. Thus, the trio managed to get three rolling Corvette chassis off of the production line and arranged to have them shipped to Modena, Italy. There, with the help of Road & Track correspondent Pete Coltrin, they managed to get in touch with Italian coachbuilder Sergio Scaglietti, famous for his design work on Ferrari road cars at the time. Scaglietti agreed to create and fit a new lightweight aluminium body to each car in secret, as Enzo Ferrari reportedly threatened to cancel Scaglietti's partnership with him after learning of the project. The resulting Scaglietti Corvette ended up weighing roughly 400 lbs less than any other Corvette at the time.
Each of the three cars assembled were unique for each owner:
Car #1, originally for Laughlin, was finished in red. It used a slightly different body than cars #2 and #3 to accommodate an existing Corvette front grille. It originally came with a 283 cu in V8 with 315 hp and a four-barrel carburetor, mated to a 2-speed automatic transmission.
Car #2, originally for Hall, was finished in blue. This version had a body more closely resembling the Ferrari 250 GT Berlinetta LWB. It came with the same carbureted V8 and automatic transmission as Car #1.
Car #3, originally for Shelby, was finished in red. This model was somewhat unique as though it used a similarly designed body to Car #2, it was the only model fitted with fuel-injection and a Borg-Warner 4-speed manual transmission. Unlike the other two members of the project, Shelby never took delivery of his car, citing that it was too expensive for his purposes for it.
However, the Scaglietti Corvette was not without its issues. Though conceived in 1959, the final projects wouldn't be completed and shipped back to the US until 1961, by which time it became clear that the aluminum bodies, though much lighter, had caused dramatic effects to the Corvette's chassis, resulting in dangerous front end lift at high speeds. Coupled with legal pressure from General Motors and Enzo Ferrari to put an end to production, and the Scaglietti Corvette project would be forever cemented as only a concept. However, many ideas from the car would prove inspirational, leading Jim Hall to found his Chevrolet-powered Chaparral racing team and Carroll Shelby to revisit the idea of a European-American sports car with the AC Cobra.
(Wikipedia)
Die Chevrolet Corvette C1 ist die erste Generation der Corvette. Der Wagen wurde von 1953 bis 1962 gebaut und in dieser Zeit mehrfach optisch wie auch technisch überarbeitet. Seit ihrem Erscheinen wurden viele Merkmale bis zur 7. Generation, der Corvette C7 weitgehend beibehalten. Dazu gehören unter anderem der 1955 eingeführte „Small-Block“-V8-Motor, die Glasfaserkunststoff-Karosserie und die vier typischen runden Heckleuchten, die 1961 eingeführt wurden.
Geschichte
Die erste Corvette wurde auf der „Motorama“ im New Yorker Hotel Waldorf Astoria im Januar 1953 der Öffentlichkeit vorgestellt. Das Publikum reagierte positiv und ein halbes Jahr danach begann die Serienproduktion.
Als zweites Serienauto nach dem in kleiner Stückzahl gebauten Woodill Wildfire hatte die Corvette C1 eine Karosserie aus glasfaserverstärktem Kunststoff. Außer der Gewichtsersparnis sprachen die größere Gestaltungsfreiheit der Designer und die schneller zu fertigenden Produktionswerkzeuge für dieses Material – anders wäre der zügige Serienstart nicht zu realisieren gewesen. An der ersten Corvette wurde sichtbar, was man aus den Originalteilen anderer Chevrolet-Modelle alles machen konnte. So wollte man den Preis niedrig halten, da man das Auto nicht von Grund auf neu konstruieren musste. Ursprünglich wurden drei Karosserievarianten als Prototypen gebaut: Der Roadster wurde die Corvette, der Fastback ging nicht in Serie und aus dem Sportsback (Kombi) wurde der Chevrolet Nomad.
Bereits sechs Monate nach der ersten Präsentation lief am 30. Juni 1953 die Serienfertigung in Flint im US-Bundesstaat Michigan an. 1954 wurde die Produktion nach St. Louis (Missouri) verlegt. Die erste Corvette wurde ab 1953 in begrenzter Stückzahl gebaut, anfangs waren es nur etwa 300 Exemplare pro Jahr. Einige davon wurden von Projekt-Ingenieuren, General-Motors-Managern und einigen ausgewählten Schauspielern und anderen Prominenten übernommen.
Der Grund für die geringe Stückzahl von nur rund 300 Stück war unter anderem die problematische Fertigung der Kunststoffkarosserie. Der 110 kW (150 bhp) starke Sportwagen war nicht schneller und dennoch teurer als die prestigeträchtigeren Modelle von Jaguar und Cadillac. Auch der etwas später erschienene Kaiser Darrin war auf den Markt nicht erfolgreich. So konnte Chevrolet im ersten Jahr nicht einmal die Hälfte der Produktion verkaufen. Es fehlte ein hubraumstarker V8-Motor mit genügend Leistung.
Noch dramatischer wurde die Lage im folgenden Jahr 1954. Statt der geplanten 10.000 Einheiten rollten nur 3.640 Corvette vom Band, von denen 1.100 Einheiten keinen Käufer fanden. Das Aus für die Corvette drohte 1955: Knapp 700 Corvette verließen die neuen Produktionsanlagen in St. Louis und dies vielleicht auch nur noch, um Flagge zu zeigen, als Ford seinen zweisitzigen Sportwagen, den Thunderbird, erfolgreich auf den Markt brachte. Innerhalb von zehn Tagen konnte Ford 3.500 Einheiten absetzen, überwiegend mit dem 156 kW (212 bhp) starken V8-Motor.
Die Rettung für die Corvette brachte Chevrolets ab 1955 verfügbarer neuer „Small-Block“-Motor mit acht Zylindern. Der neue verantwortliche Ingenieur Zora Arkus-Duntov, auch Rennfahrer, passte die Corvette an diesen Motor an, nachdem er die GM-Verantwortlichen von seinem Konzept überzeugt hatte, und legte damit die Basis für einen erfolgreichen Neustart. Er sorgte für den Einbau von Scheibenbremsen, Einspritzung und konstruierte eine schärfere Nockenwelle, um die Motorleistung zu steigern. Die Premierenfeier der überarbeiteten Corvette wurde 1956 wieder im New Yorker Hotel Waldorf Astoria ausgerichtet. Im Jahr 1958 stiegen die Corvette-Verkaufszahlen auf über 9.000 Einheiten – genug, um erstmals schwarze Zahlen zu erwirtschaften.
Um zu beweisen, dass die Corvette auch auf der Rennstrecke ein konkurrenzfähiges Auto war, nahm Briggs Cunningham 1960 mit mehreren Modellen beim 24-Stunden-Rennen von Le Mans teil. Das beste Ergebnis war ein achter Platz.
Die Corvette C1 ist immer noch sehr beliebt.
Produktionszeit war von Juni 1953 bis August 1962. Dabei wurden insgesamt 69.015 Exemplare produziert. Da die C1 noch nicht als Coupé lieferbar war, wurden ausschließlich Roadster (offene Zweisitzer mit einfachem Verdeck) gefertigt. Danach wurde die Produktion eingestellt und 1963 wurde die Corvette C2 vorgestellt.
Karosserie
Die Corvette C1 hatte eine Karosserie aus glasfaserverstärktem Kunstharz, die bis heute bei der Corvette beibehalten wird. Dadurch sparte man Gewicht und die Herstellung ist heute relativ einfach. Allerdings war die Produktion der Kunststoffkarosserie zunächst aufwändig und langwierig. Motor, Getriebe und Fahrwerk stammten von anderen Chevrolet-Modellen.
Heckflossen-Erfinder Harley Earl hatte dem offenen Zweisitzer mit der Kunststoff-Karosserie seine Form gegeben – wie ein Raubtier zeigte diese Corvette die Chromzähne ihres Kühlergrills. Die geschwungenen Kotflügel spannten sich über die Radhäuser. Die Scheinwerfer lagen unter einem Steinschlagschutzgitter, am Heck gab es angedeutete Flossen. Die Panorama-Frontscheibe war an den Seiten herumgezogen. Der symmetrisch aufgebaute lackierte Armaturenträger hatte zwei halbkreisförmige Aussparungen, deren fahrerseitige einen Einsatz mit sechs Anzeigeinstrumenten enthielt. Bis zu diesem Zeitpunkt hatte die Corvette keine äußeren Türgriffe oder Seitenscheiben. Im Jahr 1954 waren ca. 80 % der verkauften Fahrzeuge „Polo Weiß“ lackiert, rund 16 % „Pennant Blau“ und die restlichen 4 % des Modelljahres „Sportsman Rot“ und „Schwarz“.
Die erste grundlegende äußere Überarbeitung der Corvette fand 1956 statt. Die Heckflossen verschwanden völlig, dafür hielten seitliche Einbuchtungen hinter den Vorderrädern und die erste Zweifarb-Lackierung in der Modellgeschichte Einzug. Äußere Türgriffe und Seitenscheiben mit Fensterkurbel waren eine weitere Neuerung dieses Jahrgangs. Das Hardtop wurde ab Werk mitgeliefert. Die bisher in die Karosserie integrierten Frontscheinwerfer lagen nun frei und standen etwas hervor, während die bei der ersten Corvette noch herausragenden Rücklichter nun in die hinteren Kotflügel integriert wurden. Es standen zusätzliche Lackierungen und Innenfarben zur Auswahl. Mit dem überarbeiteten Fahrwerk konnte die Corvette noch mehr Leistung auf die Straße bringen. Die Verkaufszahlen stiegen 1956 auf 3467 Fahrzeuge.
1958 wurde die Corvette ein weiteres Mal überarbeitet und mit Doppelscheinwerfern ausgerüstet, außerdem um 9,2 in (234 mm) verlängert und verbreitert. Aufhängung und Chassis waren im Grunde die gleichen geblieben, ebenso die einfache Starrachse. Die 1959er-Version sah im Wesentlichen genauso aus wie ihr Vorgänger, allerdings verzichtete man in diesem Jahr auf die Chromzierleisten am Heck und die großen Lüftungsschlitze auf der Motorhaube. Das Auto bot gute Fahrleistungen und war im Vergleich mit manchen Konkurrenten gut ausgestattet und konnte so 9168 mal verkauft werden. Für das Modelljahr 1959 änderte sich nicht viel. Es entfiel etwas Chromzierat und die Sitze sowie die Türpappen wurden überarbeitet. Eine neue Hinterachsfederung mit Stabilisator erhielt die Corvette 1960.
Die Verkaufszahlen stiegen weiter an. So wurden 9.670 Fahrzeuge im Jahr 1959 verkauft, 1960 fanden sich 10.261 Käufer und 1961 dann etwas mehr, nämlich 10.939. Im letzten Jahr 1962 der ersten Generation verkaufte sich die Corvette mit 14.531 am besten in den neun Produktionsjahren.
1961 wurde die C1 ein letztes Mal außen überarbeitet. Dabei wurde die Front von den Vorgängermodellen übernommen. Das Heck wurde hingegen geändert und war nun ein Bootsheck, das sowohl bei der Baureihe der C2 beibehalten wurde, als auch noch in den folgenden Modellen C3, C4 und C5 erkennbar ist. Die seit 1955 bestellbaren seitlichen akzentuierten Flächen entfielen im Jahr 1962, die Corvette gab es nur noch einfarbig.
Die vier runden Rückleuchten führte der damals neue GM-Chefdesigner Bill Mitchell ebenfalls 1961 ein. Diesem typischen Stilelement blieb GM bis heute treu, obwohl die Leuchten ab Generation C7 zwar noch paarweise angeordnet, jedoch nicht mehr rund sind.
Motor/Fahrleistungen
Der Motor war anfangs ein nur leicht veränderter „Blue Flame“-Sechszylinder-Reihenmotor aus einem Lastwagen mit einem Hubraum von 3,8 Litern (235 in3) mit einer Kompression von 8 : 1. Höhere Verdichtung und drei Carter-Einfach-Vergaser vom Type YH steigerten die Leistung auf erst 110 imp. kW (150 bhp) und ab 1954, durch eine geänderte Nockenwelle, auf 114 imp. kW (155 bhp) bei 4200 min–1 und stellten ein maximales Drehmoment von 302 Nm bei 4500 min–1 zur Verfügung.[2] Die Corvette C1 beschleunigte damit je nach Quelle in 8 bis 11 Sekunden von 0–100 km/h. Die Höchstgeschwindigkeit wurde mit 172 bis 180 km/h angegeben. Diese Fahrleistungen entsprachen jedoch sogar für damalige Verhältnisse nicht denen eines Sportwagens.
Darum verordneten Ed Cole und Zora Arkus-Duntov der Corvette C1 eine Kraftkur: Statt des bisherigen Sechszylinders entschieden sie sich für einen „Small-Block“-V8 mit zunächst 4,3 Litern (265 in3) Hubraum und 143 kW (195 bhp) bei 5000 min–1. Der erste Chevrolet-„Small-Block“-V8-Motor und somit erste Corvette-V8-Motor kam 1955 auf den Markt. Dass ein Fahrzeug damit motorisiert war, wurde mit einem großen „V“ im Namen „CheVrolet“ an den Seiten der vorderen Kotflügel gezeigt. Mit dieser Veränderung entwickelte sich die Corvette zu einem echten Sportwagen mit sehr guten Fahrleistungen. Die Beschleunigung von 0 auf ca. 100 km/h absolvierte die Corvette mit dem V8-Motor in 8,7 Sekunden. Duntov beschleunigte die Corvette in Daytona auf eine Höchstgeschwindigkeit von 150 mph (241 km/h), was zur damaligen Zeit einen respektablen Wert darstellte. 1956 wurde ebenfalls der Motor überarbeitet. Er leistete nun in der Serienstufe 210 bhp bei 5200 min–1 mit einer Verdichtung von 9,25 : 1 und war mit einem Carter Doppel-Register-Vergaser bestückt. Als Extra konnte eine Version mit 225 bhp oder 240 bhp bestellt werden. Diese beiden Motoren waren mit einer anderen Nockenwelle und zwei Doppel-Register-Vergasern ausgerüstet. Die 225 bhp-Variante beschleunigte von 0 auf rund 100 km/h in 7,3 Sekunden.
Im Jahre 1957 kam erneut ein neuer Motor in die C1. Das auf 4,6 Liter (283 in3) vergrößerte V8-Triebwerk leistete mit der neuen Einspritzung bereits 208 kW (283 bhp) und wurde 1040 mal (etwa 11 %) verkauft. Mit exakt einem PS pro cubic inch (Kubikzoll) Hubraum (umgerechnet 16,4 cm3) war damit ein sehr hoher Wert erreicht. Von 0 auf 100 km/h beschleunigte der Zweisitzer mit der leistungsstärksten Maschine in 5,7 Sekunden; er erreichte eine Höchstgeschwindigkeit von 132 mph (212 km/h). Noch schneller war die Corvette des letzten Jahrgangs dieser ersten Modellgeneration.
Die Motorenpalette reichte dann schließlich 1958 von einem V8 mit 169 kW (230 bhp) bis zum stärksten Motor mit 213 kW (290 bhp) und Einspritzung. Ersterer beschleunigte in 9,2 Sekunden auf rund 100 km/h, letzterer benötigte für den Sprint nur 6,9 Sekunden. Am beliebtesten war aber die Grundversion mit 4,6-Liter-Motor, deren Fahrleistungen als ausreichend empfunden wurden. Ab 1960 wurden beim V8-Motor Zylinderköpfe aus Aluminium verwendet.
Die letzte 1962er-Version der Corvette C1 war mit dem 5,3-Liter-V8 (327 in3) ausgestattet. Dieser war der stärkste je lieferbare Motor für die C1. Er leistete, ebenfalls mit Einspritzung ausgestattet, 360 brutto SAE-PS und beschleunigte die Corvette auf bis zu 241 km/h. Leistungsvarianten waren ebenfalls eine 300 bhp- sowie 340 bhp-Variante.
Getriebe
Anfangs hatte das Auto die Zweigang-Powerglide-Automatik, es stand auch ein Handschaltgetriebe zur Wahl. Die Verkaufszahlen stiegen jedoch erst, als der damals neue Corvette-Chefingenieur Zora Arkus-Duntov die V8-Version mit einem Dreigang-Schaltgetriebe kombinierte.
1957 konnten Autokäufer erstmals bei der Corvette auf Wunsch ein Handschaltgetriebe mit einer Kraftstoffeinspritzung kombinieren. Das neue Automatikgetriebe besaß nun vier statt drei Stufen. Im Modelljahr 1960 wurden mehr als die Hälfte der Fahrzeuge mit dem manuellen 4-Gang-Getriebe ausgeliefert, im Jahr 1961 waren es sogar 64 %. Ab 1962 hatte das Automatikgetriebe der Corvette ein Aluminiumgehäuse.
Hybrid als Hommage
Eine Zusammenarbeit der American Made Corporation und Beijing Locomotive Co., Ltd. bietet seit 2020 unter der chinesischen Marke Songsan Motors ein, von der C1 des Baujahres 1958, inspiriertes Fahrzeug unter dem Namen SS Dolphin an. Der als PlugIn-Hybrid konstruierte Wagen beschleunigt in 4,9 Sekunden auf 100 km/h und kostet ¥ 590.000 (ca. 74.000 Euro, Stand September 2020). Der Antrieb besteht aus einem turboaufgeladenen 1,5-Liter-Ottomotor sowie einem Elektromotor, welcher von einem 16 kWh-leistenden Akku versorgt wird. Damit hat der SS Dolphin eine 90 bis 100 km rein elektrische Reichweite. Die Systemleistung beträgt 230 kW bei 535 Nm und wirkt auf ein manuelles Sechsgang-Schaltgetriebe mit Vorderradantrieb. Das Fahrzeug hat eine Länge von 4800 mm, eine Breite von 1850 mm und eine Höhe von 1390 mm.
