The Acura division of American Honda Motor Co., Inc. made waves in the automotive world with the introduction of the 1992 Acura NSX sports car. This two-seater, all-aluminum marvel was designed to deliver the thrilling performance and striking aesthetics of a mid-engine exotic, all while upholding Acura’s renowned standards for reliability and exceptional quality.
Ed Taylor, then Vice President of the Acura Division, perfectly encapsulated the significance of this vehicle: “The NSX is a milestone automobile that offers uncompromised performance and redefines the pure sports car driving experience. The NSX embodies the comfort and reliability Acura is known for, bringing an unprecedented level of quality and drive ability to the mid-engine exotic class.” This statement highlighted Acura’s ambition to not just enter the exotic sports car market, but to revolutionize it.
The World’s First All-Aluminum Production Car: An Engineering Breakthrough
The Acura NSX holds the distinction of being the world’s first mass-produced car to utilize an all-aluminum body. Every significant component was meticulously crafted from aluminum, resulting in a remarkably lightweight structure. This innovative approach yielded an exceptional power-to-weight ratio, contributing significantly to the car’s agile handling and overall performance. The comprehensive use of aluminum in the body construction alone achieved a staggering 40% reduction in weight compared to a comparable steel body.
This commitment to aluminum extended beyond the body to the chassis and suspension. The NSX featured an all-aluminum suspension system, incorporating double-wishbone suspension both at the front and rear. Special gas-charged, Honda Progressive Valve (HPV)-equipped shock absorbers were integrated to further enhance handling dynamics. To optimize grip and responsiveness, the NSX was fitted with front tires mounted on 6.5 JJ x 15 aluminum alloy wheels, while the rear boasted substantially wider 8.0 JJ x 16 wheels, ensuring a balanced and controlled driving experience.
Power and Performance: The Heart of the Acura NSX
At the core of the Acura NSX lay a potent 3.0-liter, DOHC, 24-valve, V-6 engine, generating an impressive 270 horsepower. This engine was groundbreaking, featuring the pioneering Variable Valve Timing and Lift Electronic Control System (VTEC), a first for a production vehicle in the United States. The VTEC system ingeniously modulates the lift and duration of each cylinder’s four valves, optimizing both low-end torque for everyday drivability and high RPM performance for exhilarating acceleration.
Further pushing the boundaries of engine technology, the NSX incorporated forged titanium connecting rods – another first for a production car. These lightweight rods reduced reciprocating mass, allowing the engine to rev more freely and enhancing high RPM performance. The result was breathtaking performance figures: a track-tested top speed exceeding 165 mph, acceleration from 0 to 60 mph in a mere 5.03 seconds, and a quarter-mile sprint accomplished in under 14.0 seconds. Drivers could choose between a standard 5-speed manual transmission for a purist sports car experience or an optional 4-speed automatic transmission with electric power steering for enhanced convenience.
Advanced Technology for Superior Control
The Acura NSX was not just about raw power; it was a showcase of cutting-edge automotive technology designed to provide superior control and safety. One of its standout features was Traction Control, an advanced system that automatically reduced engine power to prevent wheel spin on slippery surfaces. Unlike some contemporary traction control systems limited to low-speed scenarios, Honda R&D developed this system to function effectively across a wide range of speeds and cornering situations, truly enhancing performance driving.
Complementing the traction control was a state-of-the-art 4-channel Anti-Lock Braking System (ABS), standard on every NSX. This system provided independent control of each wheel, ensuring optimal braking performance, especially in wet or low-grip conditions. Additional engineering refinements included a torque control differential and a twin-disc clutch, further contributing to the NSX’s exceptional handling and responsiveness.
Design Inspired by the Skies: Aerodynamics and Aesthetics
The exterior design of the Acura NSX drew inspiration from the F16 jet fighter, reflecting in its aerodynamic efficiency and futuristic appeal. This influence is particularly evident in the canopy-forward design, which offered unparalleled visibility compared to other exotic sports cars of its era.
The NSX’s aerodynamic profile was meticulously honed, achieving a drag coefficient of just 0.32. Furthermore, it boasted a low lift coefficient of 0.05 and minimized yaw moment, demonstrating a comprehensive approach to aerodynamic balance. The long tail design and integrated rear spoiler were crucial elements in achieving the car’s exceptional stability at high speeds.
Inside, the NSX offered a luxurious and driver-focused environment, featuring leather-trimmed power seats, automatic climate control, an Acura/Bose® music system, a theft deterrent system, and a driver’s side airbag (SRS).
Exclusivity and Craftsmanship: Built with Precision
The Acura NSX was produced in a dedicated, state-of-the-art plant in Tochigi, Japan, situated adjacent to Honda’s R&D facility. Reflecting its bespoke nature, production was limited to just 32 hand-built vehicles per working day on an innovative, low-volume production line, emphasizing meticulous craftsmanship and attention to detail.
For the 1992 model year, the NSX was available in Grand Prix White, adding to the original color palette of Formula Red, Berlina Black, and Sebring Silver. Grand Prix White and Sebring Silver models were offered with a Black interior, while other exterior colors provided a choice of Black or Ivory interiors, allowing for a degree of personalization. Acura stood behind the quality of the NSX with a 3-year, 36,000-mile limited warranty.
The 1992 Acura NSX was more than just a sports car; it was a statement of intent from Acura, showcasing their ability to blend exotic car performance with everyday usability and legendary reliability. It solidified Acura’s position in the luxury and performance automotive market, paving the way for future innovations and cementing the NSX as an icon in automotive history.
