The C2 Corvette, also known as the original Sting Ray, is one of the most beloved and iconic American sports cars. Its combination of sleek design and powerful performance made it a standout when it launched, and it continues to captivate car enthusiasts today. While the C1 Corvette laid the groundwork, the C2 took things to a whole new level, cementing the Corvette’s place in automotive history. Here are 10 lesser-known facts about the C2 Corvette that you may not have heard before.
1. 1963 Pilot Line Cars
The birth of the C2 Corvette began with a set of “Pilot Line” or prototype cars, of which only 23 were produced. Almost all of these were convertibles, assembled alongside the 1962 Corvette models and sharing some components with them. These early cars were unique, with handmade fiberglass body panels built using mahogany wood molds. Interestingly, they even came equipped with a 1962 Chevy Nova handbrake.
2. Stingray or Sting Ray?
When the C2 Corvette first hit the scene, it wasn’t called the “Stingray” like we know it today. From 1963 to 1967, the name was actually two words—“Sting Ray.” It wasn’t until 1969, during the second year of the C3 generation, that the spelling was changed to the now-familiar “Stingray.”
3. Vinyl Roof Options
If you wanted a vinyl roof on your C2 Corvette, you had to wait until 1967. Prior to that year, convertible Corvette buyers had to stick with body-colored tops if they wanted a removable roof for cold weather. The introduction of a black vinyl top in 1967 gave customers more flexibility in their styling choices.
4. The Split Window Controversy
The 1963 Corvette coupe is one of the most coveted collector cars today, largely thanks to its distinctive split rear window. However, this feature was discontinued after just one year due to complaints from drivers who said it hindered visibility. In response, GM replaced it with a single pane of glass for the 1964 model and beyond. The rarity of the split-window coupes makes the 1963 model particularly valuable today.
5. Increased Torsional Rigidity
Beyond the switch from the split window, the 1964 Corvette also received some structural improvements. GM added more steel framework to both the coupe and convertible models, significantly increasing torsional rigidity. This steel reinforcement surrounds the passenger compartment, while the coupe benefits from additional steel overhead in the roof. The result? Sharper handling and improved cornering.
6. Off-Road Exhaust
One curious option on the C2 Corvette’s list is the “off-road service exhaust system.” Despite what the name might suggest, this wasn’t meant for off-roading. Instead, this exhaust system had fewer baffles, allowing for less restriction and a more aggressive sound. Corvette enthusiasts who wanted their car to sound meaner could opt for this system, although many drivers opted for the visually striking side-mounted exhaust instead.
7. An American First in Weight Distribution
The 1963 Corvette Sting Ray was the first American front-engine car to have over half its weight on the rear axle, making it a true innovator. This weight distribution improved the car’s balance and handling, especially when navigating tight turns. As a result, the C2 Corvette became a formidable competitor on the racetrack, holding its own against European sports cars.
8. A Functional Stinger Hood
The iconic stinger hood found on many C2 Corvettes is beloved for its bold, muscular look, but in most cases, the scoop wasn’t functional. However, there was one notable exception—the 1967 Corvette L88 427. This engine option introduced a functional hood scoop that fed fresh air into the engine, helping to boost performance. Only 20 L88 Corvettes were produced, making them incredibly rare and valuable.
9. Thermal Efficiency Boost
The 1966 Corvette introduced two powerful 427 V8 engines, and part of what made them so effective was their improved thermal efficiency. These engines featured wedge-type cylinders designed to reduce the ratio of chamber surface to chamber volume. This allowed more of the engine’s heat to be used for power instead of being lost to the cylinder walls, resulting in more horsepower and torque.
10. The Introduction of Rally Wheels
Although the C3 generation is closely associated with the iconic Rally Wheels, they actually made their debut with the C2. Starting in 1967, Rally Wheels became standard equipment on the Corvette, offering a stylish and functional option for drivers. Aluminum wheels were also available as an option for those looking for something a little different.
