1992 Corvette Specs
Total 1992 Corvettes Built- 20,479 – 5,875 Convertibles, 14,604 Coupes
New 300-HP LT1 V8, 6-speed manual transmission, ABS, Traction Control. Consider the 1992 Corvette Coupe an art form that will really move you. The Corvette Convertible is the sports car most Americans have fantasized about owning. In 1992, a lucky few will realize the dream. Corvette ZR-1 is the most talked-about sports car in a generation. It is also the car that makes Porsche, Ferrari and Lamborghini don’t want to talk about.
“Place three 1992 Corvette pilot production models at the General Motors Proving Grounds near Milford, Michigan. Add the expertise of two congenial Corvette engineers. Gain carte-blanche permission to compare and contrast the dynamic personalities of this illustrious trio on a variety of test racks. Persuade my boss that this is not another car-nut picnic, this is work. A flaming-red 6-speed 1992 Coupe is the star of the Corvette set. Engineers Scott Allman and Jim Ingle explain that, while the design is basically unchanged, there’s plenty of new technology to sharpen the reflexes of this mainline model: a new, more powerful engine under the hood, new tires, revised shock absorbers with FX3 Selective Ride Control, and a traction-control system calls ASR, which Jim Ingle tells us stands for Acceleration Slip Regulation. Supporting members of the cast are an aqua convertible and a screaming-yellow ZR-1. The Corvette Convertible is the ultimate dual-purpose machine: there is no finer way to enjoy both driving and nature at once. The ZR-1, on the other hand, is the maximum Corvette for those who take their performance very seriously. We meet at the Seven Sisters, a tight road course that reminds me of a horizontal roller coaster. The radii of the seven close-knit curves range between fifty and seventy feet. Some are flat, a few are aggressively banked. We begin with the Coupe. It is clear that the new Goodyear GS-C tires, which have a tread pattern that’s both asymmetrical and directional, have remarkable grip and very predictable breakaway characteristics. This is an ideal location to study the new ASR traction-control system. This system uses wheel-speed sensors to warn that one or both rear wheels are beginning to lose traction due to overenthusiastic throttle applications. A computer automatically rectifies that situation by first retarding ignition timing, then, if necessary, closing the throttle and applying one or both rear brakes. There’s an ASR button just above the headlamp switch which is turned off for test purposes. As a strong believer in equality, the Corvette Coupe with even amounts of steering wheel and throttle. It waltzes though the Seven Sisters like a Dance Fever grand champion. Of course, there are times when it isn’t appropriate to flick the tail wide exiting every corner. To study this side of the Corvette’s personality, switch the ASR on. The Corvette now behaves itself like a well-disciplined child. All 1992 Corvettes are equipped with ASR, including the Convertible. This car seems to say, “Why hurry?” on the Seven Sisters. I let the four-speed automatic and the grippy Goodyear tires do the work and cruise through for the cameras. Fluffy louds and the bright Michigan sky smile down upon the Corvette. Corvette roadsters must be the ride of choice in heaven. Next, we visit Black Lake, formerly known as the Fenn Holden Vehicle Dynamics Test Facility. This 57-acre monument to asphalt engineering is one continuous expanse of pavement with no curbs or light poles to interrupt the handling and maneuverability tests. To further explore the new traction-control system. The ZR-1 was parked on a pair of six-foot-long polished steel pads which do an excellent job of simulating glare ice. First, we switched the ASR off, engage the clutch, and stand on the gas. The result is exactly as expected: runaway rear-wheel spin causing the Corvette to drift a few inches to the right as it slowly creeps forward off the pads. Then we repeated the exercise with ASR activates. The rear tires chirp softly but the car moves forward straight and true. ASR doesn’t eliminate wheel spin, but it does an excellent job of minimizing the ill effects such as diminished lateral stability. The major development under the hood is a new LT1 engine which powers all Corvettes except the mighty ZR-1. Ingle explains “This is a major overhaul of the classic small-block V8. The displacement is still 5.7 liters, but the package is physically smaller and more powerful. Both the water pump and the distributor are mounted to the front of the block and driven internally by the crankshaft. There’s a new low-profile intake manifold and an exhaust manifold and an exhaust system that’s quite similar to what we’re using with the LT5 engine.” With 300 horsepower at the redline, we transfer to Milford’s two-mile-long straightaway for a taste of pure speed. This may be the most charismatic Corvette in the lineup, but it doesn’t ignore its sporting credentials. When you floor the throttle, the new LT1 engine runs for the redline. The transmission clock off each upshift-firmly and punctually. I leave the pedal on the carpet and watch the speedometer digits count up to 130 MPH. Moments later, in the yellow ZR-1, the 375 HP, 32-valve LT5 engine performs its patented disappearing act: one second you are sitting at the start of the straightaway, the next instant your gone. There is so much thrust available between 4000 and 7000 RPM that we wouldn’t be surprised to find a “NASA” label positioned directly under the ZR-1 hood. To finish the day the red coupe got up ton an indicated 142 MPH. The Lt1’s energetic horsepower curve matched to the six-speed manual transmission is a marriage worth of The Love Boat. Chevy dans faithful to the small bock engine for more than three decades recap their reward in 1992. Especially those lucky enough to own a new Corvette. -Don Sherman, editor-at-large Motor Trend Magazine
This classically American sports car continues to win the hearts of enthusiasts and the respect of competitors. Although it hardly seems possible, there was a time (circa 1953-54) when Corvette was scoffed at by those who thought a proper sports car was something Europeans knew best. Today, the cognoscenti knows better. And they will love the 1992 Coupe, for this car surpasses the Corvettes of yore with a new 300-HP LT1 version of the 5.7 Liter V8, a smooth-shifting 6-speed manual transmission, a new high-performance traction-control system and new 17-inch Goodyear Eagle Gs-C tires tuned for excellent ride and response. Corvette style? Let’s just say the mystique is still there. The 1992 Coupe is also one of the world’s most completely equipped sports cars. Standard equipment includes air conditioning, power windows, power door locks, and a Delco AM/FM stereo with cassette tape player. A standard “delay” feature for accessories continues power to the entertainment system and power windows for up to 15 minutes after the ignition key is turned to “off” or until either door is opened. Other convenience features include halogen fog lamps, front and rear cornering lamps, and dual sport mirrors (electric remote and heated). The Coupe’s one-piece removable roof panel may be lifted off for breezy, open-sky motoring. A transparent roof panel (with blue or bronze tint) is an available option. The all-glass lift-up rear hatch with remote release allows easy access to 12.6 cu. ft. of luggage space. A security shade is provided by a lockable storage compartment behind the passenger seat. Corvette for 1992 retains the widely praised 1991 exterior (revised rear appearance with quad rectangular tail lamps, wraparound front cornering lamps, aggressive 17” aluminum wheels and restyle front fender louvers). Base-coat/clear-coat paint (on fiberglass body panels, of course) provides a “wet look” shine. What’s new is what’s under the hood… a powerful new version of the 350 cubic-inch (5.7 Liter V8. It’s the latest in a long, proud line of Corvette V8 engines.
The new-for-1992 LT1 is the latest version of the legendary Corvette small-block V8. Horsepower is 300 at 5000 RPM, toque is 330 lb.-ft at 4000 RPM. The LT1 cylinder head is aluminum, basic block is cast-iron. A new one-piece low-profile intake manifold provides increased engine volumetric efficiency, i.e. better “breathing.” Angle-based ignition system and recontoured fuel rain result in greater power delivery at high RPM. A low-friction accessory drive helps air conditioning and power steering operate more efficiently, drawing less power from the engine. New Multi-Port Fuel Injection system contributes to improved fuel flow, more precise mixture of fuel and air in the combustion chamber and excellent throttle response.
The new LT1 V8 for ’92… The goal is designing the 1992 LT1 engine was to keep Corvette clearly world-class, in terms of overall power, acceleration, smoothness of power delivery and reliability. The resulting engine surpassed even the engineers’ high expectations. In fact, after a quick ride in a prototype, a development engineer remarked, “it reminds me of the ’70 LT1” (a high performance small-block V8 engine available on Corvette from 1970 through 1972 in limited numbers). And that’s how the new 1992 engine received its classic designation: LT1. The basic configuration and block are the same as in 1991, and the same as the 1970 LT1: 350 cubic inches of displacement with a bore/stroke ratio of 4.00 x 3.48. From this highly satisfactory starting point (with a 1991 HP rating of 250 at 4400 RPM), the Corvette team went to work. They added a new one-piece low-profile intake manifold and new air cleaner cover for improved engine “breathing,” a new front cover and water pump for increased efficiency, angle-based ignition timing and recontoured fuel rail for greater horsepower at high RPM, and a new low-friction accessory drive. This serpentine-type accessory drive belt is designed to outlast conventional belts. Engine cooling system improvements include a new cylinder head gasket, thermostat and seal assembly. A new-for-1992 Multi-Port Fuel Injection system contributes to improved fuel flow and precise throttle response. The bottom line: 300 HP at 5000 RPM. Not only is that a 50 HP increase from 1991, it is also more HP than the 1970 LT1 delivered. The 1992 LT1 V8 is one of the most powerful small-block Corvette V8s ever created. That’s saying something, especially when you consider that this new engine runs more cleanly and on lower octane gasoline than the Corvette V8s of years ago. The LT1 V8 is available with your choice of a four-speed automatic overdrive transmission (standard) or a remarkable smooth-shifting 6-speed manual (a no-cost option).
Traction Control: Acceleration Slip Regulation, a computer-controlled traction-control system which provides optimized acceleration and vehicle directional stability, is standard in every 1992 Corvette. When wheel-slip is detected, the traction control system pulses the anti-lock brake and momentarily reduces engine output via engine spark retardation until wheel and ground speed are nearly matched to provide well-balanced performance and greater control on a variety of road surfaces. Traction Control, combined with a standard limited-slip rear axle and new, asymmetrical, unidirectional 17-inch Goodyear Eagle GS-C tires, maximizes the real-world potential of the LT1 V8.
Four Wheel Anti-Lock Brake System: Standard in every Corvette is the Bosch ABS IIS, one of the most advanced four-wheel anti-lock brake systems available in any production automobile. ABS reduce the chance of wheel lockup during braking and is designed to help you maintain steering control even in a panic stop in rain, on snow or on ice. When called upon to do so, the four-wheel anti-lock brake system can adjust brake pressure as rapidly as 15 times per second, a rate even the most skilled professional driver cannot attain. Bosch ABS IIS is combined with four-wheel power discs for up to 1.0g of stopping power.
Selective Ride Control: Corvette’s optimal Selective Ride Control, refined and recalibrated for 1992, is an innovative suspension system designed for everyday driving. This computerized system allows the driver to select from one of three shock absorber damping levels (Touring, Sport or Performance) via a console-mounted switch. It is programmed for six automatic gradations of firmness within each mode, with firmness increasing as vehicle speed increases.
Standard PASS-Key: All 1992 Corvettes feature a standard Personalized Automotive Security System uses a small resistor pellet embedded in the ignition key within a specific resistance value. If an attempt is made to the start of the car without the proper key, the starter motor and fuel flow are rendered inoperative, preventing the car from being started for up to four minutes each time a key with the wrong resistor is used. In addition to reducing vehicle thefts, the PASS-Key system may qualify you for comprehensive insurance premium discounts.
Standard Safety Features: Occupant safety is a top priority in the design of the Corvette Coupe. Advanced safety features include a rugged steel safety cage that surrounds the passenger compartment, a driver-side air bag, lap/shoulder safety belts for both driver and passenger and controlled-crush front and rear structures.
Corvette is the official vehicle of America, a designed-in-the-U.S.A. entry in the 1992 America’s Cup Yacht race. Consider the ’92 Corvette Convertible another all-American, wind-in-the-face challenge to conventional thinking. Corvette Convertible is a lot like riding a Yacht through whitecaps at full speed, guaranteed to get the adrenaline flowing. Picture yourself (and your favorite companion) in this car, with the open road ahead of you. Now, drop the top. Put your favorite tape (or compact disc) in the optional Delco/Bose player. Enjoy the mellow background music of the finely tuned LT1 V8 and feel the rush of the wind. If ever there was a year to realize the dream of owning the Corvette Convertible, it is 1992. The style of this Corvette is sensational. The romance of top-down motoring is timeless. But it is the performance that makes this roadster a sports machine to be savored. The new 5.7 Liter LT1 V8 with Multi-Port Fuel Injection develops 300 HP at 5000 RPM, and that makes this ’92 Corvette one of the most powerful production convertibles in the world. A 4-speed automatic overdrive transmission is standard equipment. A ZF 6-speed manual transmission is a no-cost option. Both transmissions receive calibration changes for compatibility with the new LT1 engine. A significant feature of the 6-speed manual is Computer-Aided Gear Selection (CAGS). The CAGS system is designed to improve fuel efficiency during normal driving situations by directing the driver from first gear to fourth gear when accelerating lightly from a dead stop. A rapid acceleration cancels the one-to-four shift automatically. The new-for-1992 traction control system helps get all this power to the parament and helps utilize all available traction in any weather condition. Four-wheel power disc brakes with a Bosch ABS IIS anti-lock brake system are standard in every Corvette. Optional Selective Ride Control is designed to enhance ride and control with a driver-adjustable, shock-absorber valving system. The system gives the driver a choice of suspension settings – “TOUR,” “SPORT” and “PERF,” or performance. PASS-Key, the most sophisticated theft-deterrent system in Corvette history, is standard equipment. Since making its debut on the 1986 model, the totally passive PASS-Key may qualify you for comprehensive insurance discounts. You will also appreciate the convenience and comfort built into this Convertible. Standard features include power windows, air conditioning, Tilt-Wheel Adjustable Steering Column and a superb Delco AM/FM stereo with cassette tape plater. Two Delco/Bose music systems are available. The first system adds six tuned Bose stereo speakers and 200-watt power to the features of the standard stereo. The top-of-the line Delco/Bose music system includes speed-activated volume control and a stereo digital compact disc player. A standard delay feature for accessories continues to supply power to the entertainment system and power windows for up to 15 minutes after the ignition key is tuned to the “OFF” position or until the driver’s door is opened – whichever occurs first. Beautifully tailored Sport Cloth bucket seats complete this picture of total luxury. Interior options include bucket seats with leather seating surfaces, sport bucket seats and electronic-digital-control air conditioning. A lockable storage compartment is located behind the passenger seat, with additional storage space for small items in the lockable center console and glove compartment. As in every Corvette, a quieter-for-1992 ride is achieved via refined sound-deadening material improved engine isolation, and new Goodyear GC-C high-performance tires. The optional low-tire-pressure warning system monitors air pressure in each tire continuously while the vehicle is being driven. Should tire pressure fall below a predetermined point, a warning lamp in the Driver Information Center is illuminated. The easy-folding manual convertible top features an integral headliner that is designed to reduce road and wind noise. The soft-top disappears below a fiberglass panel when lowered. Choose from four top colors, depend on exterior color selected: Black (canvas), White (vinyl), Light Beige (canvas) or Blue (canvas). A new Arctic White bucket-seat interior with leather seating surfaces is optional. This option, exclusive to convertibles, is available with seven out of nine Corvette exterior colors. Worthy of note: this is a factory-built convertible, manufactured to strict quality standards at the Corvette Plant in Bowling Green, Kentucky. A body-color removable hardtop is a popular option you may also wish to consider. The lightweight (62-lb.) fiberglass hardtop features a cloth headliner and electric rear window defogger. Another option available exclusively on the Convertible is the factory-installed rear deck-lid carrier. This black-finished carrier adds both style and cargo capacity. There have been many great performance moments in the evolution of the Corvette roadster… the ’57 “fuelie,” the ’62 “327,” the ’67 tripower “427,” and the ’70 LT1 are notable examples. Now the ’92 LT1 Convertible is here, and we invite you to own this moment in Corvette history.
The super car was once, by definition, a European specialty with an unproduceable name. Today, the balance of power belongs to America and the Corvette ZR-1. The Corvette Zr-1 was introduced just two brief years ago, and the pecking order in exotic cars hasn’t been the same since. Now, some stratospherically priced European machines are being regulated to also-ran status before this made-in-the-U.S.A. sports car. Perhaps permanently. Zr-1 has graced magazine covers like no Corvette before it, and the automotive press still can’t get enough. The reason for the excitement is clear – this street-legal Chevrolet consistently generates performance numbers on the test track that were once the province of all-out race cars. At the heart of the Corvette Zr-1: The already-legendary LT5 V8. This all-aluminum 5.7 Liter engine serves up specs that have enthusiasts (and competitors) paying careful attention. Each cylinder head has dual overhead camshafts with direct love-to-lifter contact, and four valves per cylinder. Fuel delivery is by micro-processor controlled Multi-Port Fuel Injection with a 16-runner inlet manifold and two Multec injectors per cylinder. There is no distributor; ignition is via a four coil “direct-fire” system. Compression ratio is 11.0:1. Horsepower is at 375 at 5800 RPM; torque is 370 lb.-ft. at 4800 RPM. The performance is, as you might expect, brisk. But the real beauty of the LT5 engine is its ability to combine this high-RPM ferocity with low-speed civility and quiet cruising-speed operation. A multiple-throttle induction system contains the secret of LT5 tractability, within each cylinder, the intake ports, valves and cam lobes are divided into two groups, the primary being the one toward the front and the secondary to the rear. Below half-throttle, or 3000 RPM, the engine breathes through the primary ports inly. So, operation, in effect, is on three valves per cylinder. The secondary intake valve is also moving but admits no fuel-air mixture. But when you put your foot down, there’s a complete change in the ZR-1 personality. The secondary port throttle valves open to permit fuel-air mixture to enter the secondary intake valves. At this point, the engine is running on all 16 injectors and all 32 valves. The secondary intake valves, which are now admitting fuel-air mixture to the cylinders, are actuated by cam lobes, which have more duration than the “primaries.” The effect is to provide true variable valve timing, optimizing flow and producing both tractable low-speed and impressive high-speed characteristics in a single engine. A unique Power Key, with the switch located on the center console, provides the ZR-1 owner with a choice of two engine settings. When “NORMAL” is locked in, the engine runs on the primary ports only. “FULL” mode allows secondary valve operation and full-out 32-valve performance. “NORMAL” mode limited the driver to about 210 HP. Traction Control: This advanced-technology feature is standard in every 1992 Corvette. Traction Control is a computer-driven system that maximizes wheel traction to provide excellent acceleration and control on a variety of road surfaces. 6-Speed Manual Transmission: A smooth-shifting, highly acclaimed ZF 6-speed manual transmission is designed to heighten the performance of the 375 HP LT5 engine. Computer-aided gear selection (guiding you from 1st to 4th during certain light-throttle driving modes) and ratios carefully chosen for both maximum performance and low-RPM highway cruising featured. ZR-1 Chassis Technology: ZR-1’s handling prowess is the result of a carefully tuned four-wheel independent suspension (with monoleaf front and rear transverse springs). Selective Ride Control, standard in ZR-1, improves on the razor-sharp reflexes of Corvette and offers sedan-like ride quality – when desired. New asymmetrical and unidirectional tires are an integral part of the ZR-1 chassis dynamics. Front tires are P275/40ZR-17 and rears are P315/35ZR-17. The ZR-1 features distinctive bodywork (flared from the doors back) to accommodate the extra-wide rear tires. At the rear, the Zr-1 is wider than a standard 1992 Corvette. An all-disc four-wheel anti-lock brake system (Bosch ABS IIS) provides stopping power to match the performance potential of ZR-1. ZR-1 Standard Features: the 1992 ZR-1 is the most completely equipped Corvette ever. Standard equipment includes six-way power sport seats, electronic-control air conditioning, PASS-Key theft-deterrent system, and a driver-side air bag. The only options are a transparent removable roof panel or dual panels (body color and transparent). A world-class sports car is serving of a world-class sound system, and ZR-1 gets it. The standard Delco/Bose AM/FM stereo Gold Series Sound System includes electronic tuning, automatic up/down seek, six tuned Bose stereo speakers and 200 watts of natural sound. Other advanced features of this Delco/Bose stereo include a cassette tape player with auto reverse, a digital compact disc player and speed-compensated volume adjustment. Dynamic Noise Reduction (DNR) and Dolby Sound Noise Reduction are designed to reduce high-frequency “hiss” on AM/FM and cassette tape player. After driving the ZR-1, one Corvette engineer nailed its definition: “ZR-1 is Corvette, only more so.” If you’re ready for this much Corvette, your Chevrolet dealer would be delighted t show you the 1992 edition of the American Champion.
A driving environment to delight enthusiasts and luxury lovers alike. Corvette luxury is much more than fine leathers and excellent stereo systems Corvette luxury is the art of making the driver feel as one with the machine. The reclining bucket seats are contoured for comfort and for control. The optional sport seats with leather seating surfaces (standard in ZR-1) include power height, tilt, fore-aft adjuster, and a power lumbar support feature. Three new interior colors are available: Arctic White (Convertible only), Light Beige and Light Gray. Black (cloth or leather) and Red (leather only) are continued. A Tilt-Wheel Adjustable Steering Column is standard, and the design of the instrumentation places a priority on visibility, legality and ease of reach. For 1992, a revised instrument cluster features bolder gauge graphics, with more precise graduations. Gauges include analog readouts for tachometer, water temperature, oil pressure, oil temperature and volts; and digital readouts for speed, volts, oil temperature, coolant temperature, instant average fuel economy and range. Another important driver-information system is an engine oil-life monitor. It alerts the driver with a “Change Oil” light when an oil/filter change is recommended. The low-oil sensor illuminates a “Low Oil” lamp in the Driver Information Center when the oil level is one quart low. Available sound systems: a standard Delco AM/FM stereo with seek-scan, cassette tape player, and one with cassette tape player and compact disc player (the latter features speed-activated volume control and is standard in ZR-1).
