By the late 1950’s, the infrastructure of the automotive industry had begun a transformation from the monopolistic business of a few, large, corporate giants to a much more competitive and highly segmented marketplace.  A few small, relatively unknown companies from Europe were emerging, presenting competitively priced alternatives to the current American offerings, catching companies like Ford and General Motors completely by surprise.  Volkswagon had introduced the Beetle and confounded the competition by selling 200,000 or more units per year.   The introduction of this, and other “cheap” cars into the automotive market would forever change the direction of automotive marketing and would directly impact the future of the Corvette.

Despite the fact that the Corvette had yet to be profitable, General Motors management was certain that the design changes that Harley Earl had implemented in his 1956 redesign would continue to be the basis of design for future model years.  Certainly, the 1957 Corvette had shown considerable improvement in it’s numbers over the 1956 model year and, if things continued to move in that same direction, the Corvette would certainly meet financial success in the coming year.  In addition, Corvette had managed to completely dominate on the racetrack and, despite the fact that General Motors would join others in observing the racing ban that had been put in place by the Automobile Manufacturer’s Association (AMA), it had proven nearly unbeatable in it’s class.  It is commonly believed that the Corvette had performed so well in open competition throughout 1957 that it had forced Ford to “throw in the towel” on it’s two-seater Thunderbird, forcing them to instead transform it into a four door sedan.

As early as 1958, Chevrolet began developing the XP-700 Corvette as a prototype for the second generation 'Vette.

This concept model Corvette featured many styling elements that GM's new design Chief, Bill Mitchell, believed would represent the future of the Corvette.

Still, GM engineers were entertaining thoughts of unit-body construction, while the styling staff was drawing inspiration from the design styling of the immensely popular Mercedes-Benz 300SL gullwing coupe.  Drawing on inspiration from both Earl’s ‘56 Corvette and the Mercedes-Benz, a new concept car emerged that was featured at the 1956 Motorama that nearly became the basis for an all-new Corvette.  This car would go on to become known as the “Oldsmobile Golden Rocket”.

This “Golden Rocket” was a unit-body, two seat coupe that sported futuristic styling that included a slim vertical grille and a protruding snout with quad headlamps - a style that was immensely popular amongst designers in Detroit.  The Oldsmobile’s front fenders swept back the length of the body to a torpedo like rear end that was topped by small fins.   Gullwing-like sections were cut into the roof assembly to allow greater ease when entering/exiting the car.   Much like the rest of the car, the roofline also tapered back in a “boattail” fashion, with a large rear window that wrapped down and around the roof.  In all, the “Oldsmobile Golden Rocket” would become commonly recognized as the inspiration for Bill Mitchell’s Corvette Stingray seven years later.
As early as 1946, General Motors executives had come to a consensus that unit-body construction would be the path forward for cheaper unit cost and higher volume, both of which were items that Corvette needed to begin turning a profit.  Using the Oldsmobile concept car as a model, engineers began laying out a new Corvette based on the Golden Rocket’s styling.  Early models made of clay and fiberglass showed how unit body construction might help pave the way for a whole new era of Corvettes. Smaller and lighter than the current C1, it also compensated for many of the current design constratnts that current Corvette engineers were forced to deal with.  However, this first pass at a new Corvette design never completely got off the ground.  The project, whch carried the name Q-Corvette, ended up getting shelved as members of the Concept Corvette development team were pulled away to other projects that demanded the attention of those who could best help in the ever increasing sales race against Ford.  As far as the 1958 Corvette was concerned, the car would have to settle for a facelift.
From the standpoint of appearance, the 1958 Corvette was far more excessive than any of it’s predecessors.  While the car still reflected the design changes implemented in the 1956 and 1957 models, the ‘58 Corvette now sported simulated louvers on it‘s bonnet(hood), nonfunctional air intake scoops on either side of the grille and phony vents in the bodyside “coves”.   It also featured twin, chrome “suspenders” that ran from the base of the rear window down the trunklid, before ending abruptly at the rear fender.  Another notable departure from the earlier models was the addition of quad headlamps wrapped in a thick chrome bezel.  Much like the chrome “suspenders” featured on the trunk lid, chrome strip
strips ran along the tops of the fenders, accentuating the appearance of the headlamps and giving an overall “swept back “ appearance.  Lastly, the chrome “teeth” in the front grille itself were reduced from thirteen (as had been the standard in all Corvettes prior to 1958) to only nine.

The 1958 Corvette not only looked heavier with it’s many new additions and design changes, but it had actually gotten heavier.  For the first time in Corvette history, the car exceeded 3,000 pounds, which was an increase of 200 pounds over the 1957 model.However, the increase in weight was not merely due to the excesses that were included in the car’s makeover, but was the result of the increased size of the car.  The 1958 Corvette had 9.2 inches of added length and 2.3 inches of added width, bringing the car’s overall dimensions to 177.2 by 72.8 inches.  Because of the increase in weight and size, the Corvette would require the addition of radius rods to the rear suspension, which would help offset some of the behavioral issues the car experienced under hard acceleration conditions.
While the exterior revisions to the 1958 Corvette exuded excess from almost every angle, the interior revisions to the car were no less substantial, although they were better received.   A significant redesign of the instrument cluster at the request/direction of Zora Arkus-Duntov resulted in all of the gauges (save for the clock) to be placed directly in front of the driver in a binnacle.  After the repeat criticisms of instrument placement in earlier models, this change seemed only natural to the Corvette’s design team.   The new cluster consisted of a 160-mph speedometer which dominated most of the dashboard, while a smaller 6000 rpm tachometer was placed ahead of it on the steering column.  Flanking the tachometer on each side was a pair of standard instrument gauges that monitored fuel levels, oil pressure, engine temperature and battery charge. 

Emerging from the dashboard and mating with the center console was a narrower, vertical console which housed the heater controls, the clock and an optional “Wonder Bar” signal-seeking radio.  While relatively unique for it’s time, this arrangement of controls was virtually identical to the standard layout in automobiles today.  The passenger side of the dashboard featured a grabbar mounted in front of a semicircular dashboard that was cut away from the bar itself, allowing passengers to “hold on” in the event of a sharp turn or during sudden acceleration.  A locking glove compartment was fitted between the seats just below the release button for the convertible top.

Other changes were made to the interior as well.  The interior door panels were remodeled to include reflectors that had been added at arm level for nighttime safety.  Upholstery now featured a new “pebble grain” fabric.  Even seatbelts, which had been practically unheard of before that model, were standard issue - factory installed in the 1958 Corvette.
Regardless of personal opinion surrounding the 1958 Corvette’s appearance, there were no questions what the performance factor would be.  Nearly unchanged from the 1957 Corvette, the ‘58 continued to utilize the 283 engine.  Now officially rated at 290 horsepower (at 6,200 rpm’s), the fuel injected, Duntov-cam 283 continued to flourish beneath the hood of the 1958 Corvette as the top level engine for that year’s model run.  Similarly, a twin carburetor version of the engine continued to be offered as an option, offering drivers an uncompromising 270 horsepower engine.  Despite this fact, few buyers opted for the carbureted version of this engine.  Surprisingly, it was the base level 230 horsepower V-8 engine that buyers sought out.    This base model engine was installed in nearly half of the 1958 models.  Only 1,500 Corvettes were actually fitted with the fuel injection option, and of those only 1,000 featured the 290 horsepower setup, the other 500 belonging to the 250 horsepower version of the Corvette.

For those enthusiasts that had continued to demand uncompromising speed and performance  after the introduction of the 1958 model, Chevrolet continued to offer a near race-ready version of the Corvette, which they made available at local dealerships across the country - and at prices that made buying even the highest end Corvette affordable.  With upgrades ranging from a high performance, 290 horsepower, fuel injected engine, Positraction, heavy-duty metallic brake and suspension and a four speed manual transmission, the total difference in cost between the base priced Corvette and it’s racing counterpart was about $1500.00.  Considering that these upgrades allowed the ‘58 Corvette to rival such competitors as Jaguar, Ferrari and Porsche, there was no question that Corvette was the best performance for the price.  It is reported that Corvette’s which were built to include the aforementioned upgrades came with a warning label on their windshields that stated “This car is not intended for street use.”
While General Motors continued to shy away from advertising the race-performance capability of the Corvette, due mostly to the “anti-racing” edict that had been passed the previous year, it did focus it’s advertising dollars on promoting the most positive aspects of this new car, running campaigns that included such statements as “(a) silken cyclone of a V-8”.  Chevrolet knew that the Corvette was a showcase of performance and horsepower that would attract buyers en masse. 

And it did.

Despite some of the extreme changes to it’s body styling, the 1958 Corvette was the first vintage of Corvette to turn a profit for General Motors.  In all, Chevrolet sold 9,168 Corvettes in the 1958 model year, which was doubly impressive when considering that the Corvette sales were up (47% over the 1957 Corvette and a staggering 150% over the 1956 Corvette) despite a year in which a financial recession had wrought havoc on the competition, leaving few manufacturers to actually turn a profit that year.  In fact, save for Ford’s new four-seat 1958 Thunderbird (and very few others), Corvette alone proved successful in the domestic automotive market

By 1958, Corvette had become recognized as a world contender and performer both in the retail automotive market as well as in the domestc and international racing circuits.

Consumers and speed fanatics, enthralled with ever increasing horsepower and performance, began to recognize the Corvette as a rival of the Porsche, despite the fact that the Corvette (with upgrades for racing) sold for a mere $4,100 compared to Porsche's (and other European manufacturers) $10,000 and greater price tags for a similarly built European racer.
