1989 Corvette Specs

Total 1989 Corvettes Built- 26,412 – 9,749 Convertibles, 16,663 Coupes

Corvette Coupe: Sports car engineering has now been unequivocally elevated to a fine art. Corvette Coupe, the grand touring edition of America’s exotic car, offers a stunning combination of advanced design, luxurious comfort and stellar performance. Think of it as an object of art with a 5.4 second 0 to 60 MPH. The editors of leading automotive magazines agree: Corvette Coupe is one of the world’s great cars. By way of example, Car and Driver magazines has included Corvette in its “Ten Best” list for four years running. For those who prefer a closed sports car (and the majority of the world’s “supercars” take this configuration), this Corvette offers a unique advantage: a one-piece removable roof panel that combines Convertible flair with the security of a coupe. The Coupe is also the most aerodynamic Corvette, an important reason why this is the body style selected by professional racing teams. In fact, the current-generation Corvette Coupe, specially modified for racing, has won more SCCA-sanctioned competition events than any other car in its class. Yet the street version of Corvette is one of the world’s most refined grand touring automobiles, as composed on the interstate (or autobahn) as it is aggressive in wheel-to-wheel competition. Exterior Design: The 1989 Coupe is unmistakably Corvette, from the dramatic sweep of the hood to the wraparound rear glass. Highlights of the exterior design include: Lustrous base-coat/clear-coat paint, newly standard 17” x 9 ½” cast-aluminum wheels and P275/40ZR-17 unidirectional Eagle tires, retractable halogen headlamps, halogen fog lamps, and front and rear cornering lamps, frameless glass rear hatch with three remote releases, and of course, corrosion-proof fiberglass body panels. The Corvette Interior: Corvette offers superbly luxurious and ergonomically correct seating for two. This exciting sports car environment includes: Standard sport cloth bucket seats are new styled. New leather seats and a new leather sport seats with power adjustments are optional. Complete electronic instrumentation with analog and digital displays. Standard air-conditioning, AM/FM stereo with cassette player, power windows, power door locks, power mirrors, Tilt-Telescopic steering wheel and intermittent wipers.

Corvette Convertible: Simply put, its styling is like a breath of fresh air. Corvette Convertible provides a perfect balance of top-down exhilaration and performance technology unique to Corvette. And many drivers will have their Corvette no other way. The emotional appeal of the Convertible Corvette is undeniable – and enduring. Decades from now, this car will be remembered as a milestone achievement in automotive artistry. Convertible engineering: Significantly, this Corvette has been designed as a Convertible. To ensure the highest quality standards, the Convertible is custom-crafted on a special final assembly line within the Bowling Green, Kentucky Corvette Plant. Convertible specifics include: A manually operated, aerodynamically designed Convertible top with headliner and acrylic rear window. 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, fully independent suspension tuned specifically for the Convertible. Naturally the Convertible is equipped with a full roster of luxury features, including air conditioning, Delco AM/FM stereo with cassette tape player, power windows and door locks, and Tilt-Telescopic steering wheel. Optional equipment includes the acclaimed Delco/Bose stereo sound system, electronic control air conditioning and leather interior trim in a choice of five colors.

Performance: The king of the production sports car is obviously intent on retaining its crown. Corvette is a creature of raw power, sophisticated performance features and state-of-the-art sports car comfort. It continues to be truly phenomenal machine – one designed to have its way with any road. An automobile’s track record says a lot about stamina under pressure. And after winning the Sports Car Club of America’s Escort Endurance Championship three years running. Corvette has established that there is no real competition for America’s own production sports car. So, 1988 ushered in the SCCA Corvette Challenge 50 world-class drivers with identical Corvettes in a 10-race series. The series features identical stock Corvettes equipped with the Z51 Performance Handling Package and safety modifications necessary for racing. The reward for people who pilot Corvettes to racing victories is, in a great part, glory. The 1989 Corvette owner’s reward is an automobile improved in dozens of different ways as a direct result of racing experience. 5.7 Liter V8 With Tuned-Port Fuel Injection: At the heart of Corvette performance is the 5.7 Liter V8 with TPI. In addition to one of the world’s most advanced fuel management systems, this V8 features aluminum cylinder heads, high-left camshaft and a low-restriction dual exhaust system. The result is exotic-class power with dramatic low-end punch. New 6-Speed Manual Transmission: Corvette ups the performance ante with a 6-speed manual transmission. A unique feature of this fully synchronized transmission is computer-aided gear selection, helping to ensure proper gear selection during certain driving modes. The 6-speed is a no-cost option; a 4-speed automatic overdrive transmission is standard equipment. Bosch ABS II Anti-Lock Braking System: This advanced braking system helps the driver to retain maneuverability under full braking. When called upon to do some the computer-controlled anti-lock system can adjust brake pressure as many as 15 times per second, a rate even the most skillful driver cannot attain. Bosh ABS II is combined with a four-wheel disc system for state-of-the-art stopping power. 4-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. The specifications also include power rack-and-pinion steering, an aircraft-inspired “uniframe” and unidirectional Goodyear Eagle ZR40-series 17” tires. For 1989, Corvette performance is enhanced with standard Delco/Bilstein gas-charged shocks and fast-ration steering (13:1). Optional Z51 Package: The Z51 Performance Handling Package adds competition-born precision to Corvette ride and handling. The Package includes heavy-duty front and rear springs and stabilizer bars, heavy-duty brakes, heavy-duty radiator, radiator boost, cooling fan, 3.54:1 rear axle ratio, 8 ½ inch ring gear and power steering cooler. The Z51 Performance Handling Package is available on Corvette Coupe with 6-speed manual transmission only. Recommended for specialized uses. Selective Ride Control: Bilstein Selective Ride Control (RPO Fx3) is an innovative new suspension option available exclusively on the 1989 Corvette Coupe with the Z51 Performance Handling Package and 6-Speed manual transmission. Fx3 allows the driver to select one of the three system settings (touring, sport, or perf) by rotating a switch on the console panel. Each switch position provides six different shock absorbers damping levels – depending on vehicle speed. As speed increases, damping levels automatically increase. FX3 is an electro-mechanical system that uses electric motors to vary the proportioning valve orifice in each shock absorber to change the shock’s damping characteristics. With the help of a computer-control module, superior ride quality as well as a stunning handling can be achieved simply by flipping a switch.
