1990 Corvette Specs

Total 1990 Corvettes Built- 23,646 – 7,630 Convertibles, 16,016 Coupes

Even in the rarified atmosphere of 150-MPH sports cars, Corvette stands alone. Corvette for 1990 is the exotic American, with world-class technology, incomparable style and V8 performance that has humbled some of Europe’s finest. If the idea of a high-performance sports machine with the highly civilized nature of a luxury automobile intrigues you, compare this car, the 1990 Corvette by Chevrolet, with any other. We think you will be impressed.

5.7 Liter V8 With Tuned-Port Injection: At the heart of Corvette performance is the standard 5.7 Liter V8 with Tuned-Port Injection. Other features of this 245-HP V8 include aluminum cylinder heads, high-left camshaft and roller valve lifters.

Standard Luxury Features: Standard Equipment in every Corvette includes air conditioning, AM/FM stereo sound system with cassette tape player, leather-wrapped comfort-tilt steering wheel, Electronic Speed Control, power door locks, power windows and intermittent wipers.

PASS-KEY: Corvette’s standard PASS- (Personal Automotive Security System) Key electronic auto-theft system has proven itself the most effective theft deterrent Chevrolet ahs ever offered. PASS-Key is a special ignition system utilizing a module with a resister decoder and an ignition key with a pellet of specified resistance.

Anti-Lock Braking System: This is one of the most advanced braking systems available in a production automobile, and it is standard on every 1990 Corvette. Bosch ABS II (Anti-Lock Braking System) helps the driver to retain maneuverability under full braking. Bosch ABS II is combined with a four-wheel power disc system for up to 1.0g of stopping power.

Four-Wheel Independent Suspension: The precisely engineered Corvette suspension includes fiberglass-composite front and rear transverse springs with computer-selected spring rates, a rear independent design with 5-link connections and forged-aluminum components.

Selective Ride Control: Bilstein Selective Ride Control (FX3) is an innovative suspension option available exclusively on Corvette Coupe with the optional Z51 Performance Handling Package and 6-Speed manual transmission. FX3 allows the driver to select from one of three system settings (Touring, Sport or Performance).

Corvette Coupe: The coupe version of the 1990 Corvette combines awesome performance and aero style with unexpected luxury. There can be no mistaking the smooth lines of this car for any other. And those lines promise performance the Corvette Coupe delivers in generous measure. In fact, the Coupe’s aero profile and lighter weight (compared with Corvette Convertible) make it the body style most often selected by professional racing teams.

Yet the true beauty of this car is its refined character. Corvette is as composed on the interstate (or autobahn) as it is aggressive in wheel-to-wheel sanctioned racetrack competition. There is an alluring dual nature to Corvette Coupe that makes it a popular choice for so many sports car enthusiasts. During the week, it fits your fast-paced lifestyle with a high degree of performance, personal style, and a generous roster of luxury appointments. For those weekend escapes, the one-piece removable roof panel may be lifted off for breezy open-sky motoring. The dramatic appearance of Corvette Coupe is further enhanced with lustrous base-coat/clear-coat paint in a choice of seven colors, new lighter-weight 17” x 9 ½” cast-aluminum wheels and P275/40ZR-17 unidirectional Goodyear Eagle tires, retractable halogen headlamps and halogen fog lamps. Performance options available only on Corvette Coupe include: The Z51 Performance Handling Package featuring components proven in the Corvette Challenge racing series.  Selective Ride Control, a computerized system allowing the driver to select one of three suspension settings (Touring, Sport or Performance) via a console-mounted switch.

Corvette Convertible: Corvette is the car most Americans have fantasized about owning. And for those lucky enough to experience it, the Convertible adds open-sky motoring to the many pleasures of Corvette ownership. There is undoubtedly a certain magic about the Corvette Convertible. Vintage models routinely sell for many times their original price. The 1990 edition provides a perfect balance of top-down exhilaration and performance technology. Selecting the Convertible version of the 1990 Corvette will be a most rewarding decision. You ger the BOSCH ABS II anti-lock braking system, the mighty 5.7 Liter V8 with Tuned-Port Fuel Injection, the choice of 6-speed manual or 4-speed automatic transmission, the all-new interior and the PASS-Key security system. You get Corvette. And then some. Corvette specifics include: A manually operated convertible top with headliner and vinyl rear window with improved scratch and fade resistance. Choose from three top colors, depending on exterior color selected: Black, White or Saddle; A covered well into which the top completely disappears. There is no unsightly boot to mar the top-down appearance; an optional body-color convertible hardtop. This 64-lb. removable hardtop features a cloth headline and electric rear window defogger; An optional rear deck-lid carrier. This black-finished carrier adds both style and function to the Corvette Convertible.

Instrument Panel: An excellent instrument panel is one that communicates instantly and clearly to the driver and positions all operating controls within easy reach. The new Corvette instrument panel is a study in excellence. And it looks like something out of a jet fighter plane. Jet fighter pilots, and anyone else who appreciates excellence in design, will approve of the new 1990 Corvette instrument panel. The redesigned interior combines classic Corvette wraparound instrument panel/console flavor with state-of-the-art ergonomics and an advanced electronic information center. Features include a new steering wheel, new glove box and a larger center console with lock. Instrumentation includes electronic liquid-crystal displays, large-readout digital speedometer and analog tachometer, plus gages for oil pressure, oil temperature and volts. A supplemental inflatable restraint system (air bag) is a new safety feature standard on all 1990 Corvettes. The S.I.R. system is designed to provide added protection for the driver if your Corvette is involved in a moderate to severe frontal collision. For maximum protection in frontal and all other collisions, both driver and passenger should be properly restrained with safety belts. The Supplemental Inflatable Restraint system is in the hub of the steering wheel.

Interiors: The Corvette interior is designed to American tastes. With comfortable seating. Powerful air conditioning. Advanced sound systems. And power everything. It is fair to say the 1990 Corvette is an extremely well-equipped, driver-oriented automobile. In fact, few cars in the world can match Corvette on the single criterion of creature comfort. The following interior features are standard in every Corvette: superbly luxurious and ergonomically correct seating for two, with a choice of standard sport cloth or optional leather buckets; air conditioning, power windows, power door locks, leather-wrapped Comfort-tilt steering wheel and intermittent wipers; Delco AM/FM stereo radio with Seek and Scan, cassette tape player, digital clock and power antenna; Electronic Speed Control with Resume Speed feature; and dual electrically adjusted and heated mirrors.
