The second generation (C2) Corvette, which introduced Sting Ray to the model, continued with fiberglass body panels, and overall, was smaller than the first generation. The C2 was later referred to as mid-years. The car was designed by Larry Shinoda with major inspiration from a previous concept design called the "Q Corvette," which was created by Peter Brock and Chuck Pohlmann under the styling direction of Bill Mitchell. Earlier, Mitchell had sponsored a car known as the "Mitchell Sting Ray" in 1959 because Chevrolet no longer participated in factory racing. This vehicle had the largest impact on the styling of this generation, although it had no top and did not give away what the final version of the C2 would look like. The third inspiration was a Mako Shark Mitchell had caught while deep-sea fishing.
For 1964 Chevrolet made only evolutionary changes to the Corvette. Besides the coupe's backbone window, the two simulated air intakes were eliminated from the hood, though their indentations remained. Also, the decorative air-exhaust vent on the coupe's rear pillar was made functional, but only on the left side. The car's rocker-panel trim lost some of its ribs and gained black paint between those ribs that remained; wheel covers were simplified; and the fuel filler/deck emblem gained concentric circles around its crossed-flags insignia. Inside, the original color-keyed steering wheel rim was now done in simulated walnut.
A few suspension refinements were made for 1964. The front coil springs were changed from constant-rate to progressive or variable-rate and were more tightly wound at the top, while leaf thickness of the rear transverse spring was also altered thus providing a more comfortable ride with no sacrifice in handling. Shock absorbers were reworked toward the same end. The 1964 Corvette arrived with a new standard shock containing within its fluid reservoir a small bag of Freon gas that absorbed heat. Chevy added more sound insulation and revised body and transmission mounts for the 1964 Corvette. It also fitted additional bushings to quiet the shift linkage and placed a new boot around the lever. The result was a more livable car for everyday transportation.
Drivetrain choices remained basically as before but the high-performance pair received several noteworthy improvements. The solid-lifter unit was massaged with a high-lift, long-duration camshaft to produce 365 bhp and breathed through a big four-barrel Holley carburetor instead of the base engine's Carter unit. The fuel injected engine also gained 15 horsepower, bringing its total to 375, but at a then-hefty $538.00. Although transmission options remained ostensibly the same for 1964, the two Borg-Warner T-10 four-speeds gave way to a similar pair of gearboxes built at GM's Muncie, Indiana, transmission facility. Originally a Chevy design, it had an aluminum case like the Borg-Warner box but came with stronger synchronizers and wider ratios for better durability and drivability.
For its third season, the 1965 Corvette Stingray further cleaned up style-wise and was muscled up with the addition of an all-new braking system and larger powerplants. 1965 styling alterations were subtle, confined to a smoothed-out hood now devoid of scoop indentations, a trio of working vertical exhaust vents in the front fenders that replaced the previous nonfunctional horizontal "speedlines," restyled wheel covers and rocker-panel moldings, and minor interior trim revisions. The 1965 Corvette Stingray became ferocious with the mid-year debut of a big-block V-8, the 425 hp (317 kW) 396 in³ (6.5 L) ("big block") V8. Ultimately, this spelled the end for the Rochester fuel injection system, as the carbureted 396/425 hp option cost $292.70 to the fuel injected 327/375 hp's $538.00. Few buyers could justify $245 more for 50 hp (37 kW) less, even if the FI cars offered optional bigger brakes not available on carburated models. After only 771 fuel injected cars were built in 1965, Chevrolet discontinued the option. It would be 18 years until it returned.
Four-wheel disc brakes were also introduced in 1965. The brakes had a four-piston design with two-piece calipers and cooling fins for the rotors. Pads were in constant contact with the rotors, but the resulting drag was negligible and didn't affect fuel economy. Further, the light touching kept the rotors clean and didn't diminish pad life, which was, in fact, quite high: a projected 57,000 miles for the front brakes and about twice that distance for the rear binders. Total swept area for the new system was 461 square inches, a notable advance on the 328 square inches of the previous all-drum system. Per pending federal regulation, there was also a dual master cylinder with separate fluid reservoirs for the front and rear lines. Road testers rightly applauded the all-disc brakes. A side exhaust system appeared as an option as did a telescopic steering wheel. Also available were alloy spinner rims, at US$322 a set.
